Description

Technical Field

[0001] The present invention relates to the technical field of tooling transportation, and in particular to a tooling vehicle and a tooling vehicle positioning component. Background Art

[0002] Material transport vehicles are widely used in the automated production of electrical appliances such as air conditioners, i.e., in the transportation of parts, because they can effectively improve production efficiency, reduce the need for manual handling, and reduce labor costs. When using a vehicle to transfer parts to the next station, automated equipment such as manipulators and robotic arms are usually used to transfer the parts on the vehicle; and at this time, the parts on the vehicle need to be precisely in place so that the automated equipment can smoothly grab and transfer the parts. Currently, parts transported by vehicle are prone to deviation, resulting in insufficient accuracy of the parts after transportation. The transfer equipment at the next station needs to reposition the parts before the transfer operation can be carried out, affecting production efficiency. Summary of the invention

[0005] In a first aspect, the present invention provides a tooling vehicle for transporting parts, the tooling vehicle comprising:

[0006] A loading platform, used for carrying the parts;

[0007] A plurality of installation positions are distributed at intervals on the loading platform;

[0008] A plurality of first limiting structures are respectively arranged at the installation positions, and at least one placement area is formed between the plurality of first limiting structures;

[0009] The part can be placed in the placement area, and the peripheral side of the part abuts against the first limiting structure, so that the plurality of first limiting structures limit the part.

[0010] Beneficial effect: The present invention provides a tooling vehicle, which installs multiple first limiting structures in different installation positions to form a placement area where parts can be placed; when the parts are placed in the placement area, multiple positions on the circumference of the parts can abut against the multiple first limiting structures, thereby limiting the parts and avoiding displacement of the parts on the loading platform during transportation, ensuring that the positions of the parts on the tooling vehicle are fixed, thereby ensuring the accuracy of the parts after being transported by the tooling vehicle when they arrive at the next workstation.

[0011] In an optional embodiment, the first limiting structure is configured as a columnar structure and is extended in a direction away from the loading platform, and a plurality of the parts can be stacked in the placement area.

[0012] Beneficial effect: The first limiting structure is configured as a columnar structure extending away from the loading platform, so that the placement area formed between multiple first limiting structures has sufficient vertical space to facilitate stacking of multiple parts in the placement area, ensuring that the positions of the parts on the tooling vehicle are fixed while improving the efficiency of the tooling vehicle in transporting parts.

[0013] In an optional embodiment, the loading platform comprises:

[0014] A support frame is provided with a plurality of beams arranged in a staggered manner;

[0021] In a second aspect, the present invention further provides a tool vehicle positioning assembly, comprising:

[0022] A positioning device, which can be fixedly arranged relative to the transfer device, the positioning device includes a first guide frame and a second guide frame arranged relatively to each other, and a connecting frame connected between the first guide frame and the second guide frame, wherein the first guide frame, the second guide frame and the connecting frame together form a positioning space;

[0023] The tooling vehicle described in the above embodiment, wherein at least one side of the loading platform of the tooling vehicle along the first direction is provided with a second limiting structure, and the second limiting structure is provided with an abutment portion capable of approaching or moving away from the loading platform;

[0024] When the tooling vehicle enters the positioning space, the abutting portion is used to abut against the first guide frame and / or the second guide frame to limit the tooling vehicle in the first direction.

[0025] Beneficial effect: The present invention also provides a tool vehicle positioning assembly, and a positioning device fixedly arranged relative to the transfer equipment provides a positioning space for parking the tool vehicle. The abutment portion on the second limiting structure that can be telescopically adjusted relative to the loading platform abuts against the first guide frame and the second guide frame to limit the tool vehicle in the left and right directions, thereby preventing the tool vehicle from shifting left and right when it arrives at the transfer equipment and is ready to unload and transfer parts, thereby ensuring that the position of the tool vehicle itself and the positions of the parts on it are fixed, thereby ensuring the accuracy of the parts transported by the tool vehicle when they arrive at the next workstation.

[0026] In an optional implementation, the second limiting structure includes:

[0027] A fixed block, fixedly connected to the lower part of the loading platform of the tooling vehicle and located on at least one side of the loading platform along the first direction;

[0030] Beneficial effects: Mechanical adjustment of the abutment portion set as the guide wheel to move closer to or away from the loading platform is achieved through the cooperation of the adjusting screw, the fixing block and the adjusting block; setting the abutment portion as the guide wheel improves the running smoothness of the tooling vehicle entering the positioning device.

[0031] In an optional embodiment, the tooling vehicle positioning assembly further includes:

[0032] A third limiting structure is located at a side of the first guide frame and / or the second guide frame away from the connecting frame;

[0079] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0080] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0081] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0082] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0083] At present, parts transported by tooling vehicles are prone to deviation, which is mainly manifested in the following two aspects:

[0084] First, the parts on the tooling vehicle are prone to shaking and displacement during transportation, causing the parts to shift in position on the tooling vehicle.

[0085] Secondly, when the tooling vehicle is transported to the next workstation to prepare for the use of automated equipment to grab, transfer and unload the parts, the tooling vehicle itself is not in place, causing the parts on it to shift in position.

[0086] The above two situations will lead to insufficient precision of the parts after transportation, which will cause the transfer equipment of the next station to reposition the parts before the transfer operation can be carried out, affecting production efficiency. To this end, the present invention provides a tooling vehicle and a tooling vehicle positioning assembly to solve the problem of insufficient precision of the parts after transportation by the tooling vehicle.

[0087] Combine the following Figure 1-Figure 8 , describing an embodiment of the present invention.

[0088] According to an embodiment of the present invention, on the one hand, a tooling vehicle is provided for transporting a part 400, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes: a loading platform 110 , a plurality of installation positions 130 and a plurality of first limiting structures 140 .

[0089] The loading platform 110 is used to carry the part 400, and a plurality of mounting positions 130 are spaced apart and distributed on the loading platform 110; a plurality of first limiting structures 140 are respectively detachably installed on at least some of the mounting positions 130, and at least one placement area 150 is formed between the plurality of first limiting structures 140; the part 400 can be placed in the placement area 150, and the peripheral side of the part 400 abuts against the first limiting structure 140, so that the plurality of first limiting structures 140 limit the part 400.

[0090] In the above embodiment, multiple first limiting structures 140 are installed in different installation positions 130 to form a placement area 150 where the part 400 can be placed; when the part 400 is placed in the placement area 150, multiple positions on the circumference of the part 400 can abut against the multiple first limiting structures 140, thereby limiting the part 400 and preventing the part 400 from shifting on the loading platform 110 during transportation, ensuring that the position of the part 400 on the tooling vehicle is fixed, thereby ensuring the accuracy of the part after being transported by the tooling vehicle when it arrives at the next workstation.

[0091] Specifically, a roller 120 is provided at the lower part of the loading platform 110, and the roller 120 is rotatably arranged to drive the loading platform 110 to move when driven; a handle frame 180 is provided on one side of the loading platform 110, wherein two groups of rollers 120 close to the handle frame 180 are configured as universal wheels for steering, and the operator pushes or pulls the handle frame 180 to drive the roller 120 to rotate, thereby driving the loading platform 110 and the parts 400 thereon to move; the mounting position 130 is specifically configured as a mounting hole position, and the bottom of the first limiting structure 140 can be inserted into the mounting hole position. The first limiting structure 140 is detachably connected to the mounting position 130 so as to facilitate replacement or adjustment of the position of the first limiting structure 140 to accommodate parts 400 of different specifications and sizes; the portions of the multiple first limiting structures 140 exposed from the loading platform 110 define different placement areas 150 for placing parts 400 of different shapes, so that when the parts 400 are placed in the placement areas 150, the multiple first limiting structures 140 are used to limit the circumference of the parts 400, that is, to limit the parts 400 in the horizontal direction, that is, Figure 2 , Figure 3 shown.

[0092] Furthermore, by defining different placement areas 150 through a plurality of first limiting structures 140, parts 400 of different shapes can be limited. It should be noted that the shape of the placement area 150 formed by the plurality of first limiting structures 140 in this embodiment is not necessarily the shape of the outer peripheral contour of the part 400. For example, if the part 400 is set as a trapezoidal structure part, then only three first limiting structures 140 need to be respectively set corresponding to the two waists and the bottom edge of the trapezoidal structure part to form a triangular placement area 150, so that the trapezoidal structure part can be stably limited. It can be understood that when three first limiting structures 140 are set, a triangular distribution structure is formed by using the three first limiting structures 140, and the stability of the triangular structure can be used to limit the peripheral side of the part 400 in a relatively stable manner.

[0093] Furthermore, in this embodiment, four placement areas 150 are formed between the plurality of first limiting structures 140 .

[0094] Furthermore, this embodiment does not limit the specific arrangement of the multiple installation positions 130 distributed at intervals on the loading platform 110. As an implementation method, the multiple installation positions 130 are evenly distributed on the loading platform 110 in a matrix form, and the distance between two installation positions 130 is reasonably designed to be as small as possible, so that the placement area 150 formed by the multiple first limiting structures 140 can form more shapes, thereby improving the versatility of the tooling vehicle; as another implementation method, several common parts 400 that need to be transported are determined, and the distribution method of the multiple installation positions 130 is specifically designed corresponding to the peripheral contour shape of each part 400, so that the placement area 150 formed by the multiple first limiting structures 140 can form a shape corresponding to the peripheral contour of the part 400, thereby reducing the modification cost or production cost of the tooling vehicle.

[0095] Furthermore, if Figure 2 , Figure 3 As shown, in this embodiment, the first limiting structure 140 is detachably connected to the mounting position 130 set as the mounting hole position, so as to adjust the position of the first limiting structure 140 to adapt to parts 400 of different specifications and sizes, and there is no restriction on the detachable connection method of the first limiting structure 140 and the mounting position 130 set as the mounting hole position. As an implementation method, a snap-fit ​​structure of a boss and a groove is designed between the first limiting structure 140 and the mounting position 130, and the first limiting structure 140 is inserted into the mounting position 130; as another implementation method, the mounting hole position of the mounting position 130 is set as an internal threaded hole, and the first limiting structure 140 is screwed to the internal threaded hole and the mounting position 130 for threaded connection.

[0096] In some embodiments, Figure 1 , Figure 2 , Figure 3 As shown, the first limiting structure 140 is configured as a columnar structure and is extended in a direction away from the loading platform 110 , so that a plurality of parts 400 can be stacked in the placement area 150 .

[0097] In the above embodiment, the first limiting structure 140 is configured as a columnar structure extending in a direction away from the loading platform 110, so that the placement area 150 formed between the multiple first limiting structures 140 has sufficient vertical space to facilitate stacking of multiple parts 400 in the placement area 150, thereby ensuring that the position of the parts 400 on the tooling vehicle is fixed while improving the efficiency of the tooling vehicle in transporting the parts 400.

[0098] Specifically, the first limiting structure 140 is set as a columnar structure, the mounting position 130 is set as a mounting hole position corresponding to the shape of the columnar structure, the inner wall of the mounting position 130 is provided with a boss, and the bottom of the first limiting structure 140 is provided with a groove corresponding to the boss. The first limiting structure 140 is inserted into the mounting position 130 so that the boss and the groove form a snap-fit ​​fit, thereby realizing a detachable connection between the first limiting structure 140 and the mounting position 130.

[0099] Furthermore, in this embodiment, each vertical placement space of each placement area 150 formed between the multiple first limiting structures 140 can stack seven to ten parts 400, and the four placement areas 150 can place a total of thirty to forty parts 400.

[0100] In some embodiments, Figure 1 , Figure 4 As shown, the loading platform 110 includes a support frame 111 , a beam body 112 and a plurality of mounting blocks 113 .

[0101] The support frame 111 is provided with a plurality of beams 112 arranged in a staggered manner; a plurality of mounting blocks 113 are connected to the beams 112 , and each mounting block 113 is provided with at least one mounting position 130 .

[0102] In the above embodiment, the support frame 111 and the multiple beams 112 thereon form the structural basis of the loading platform 110, and a plurality of mounting blocks 113 connected to the beams 112 provide opening positions for the mounting positions 130, thereby simplifying the structural form of the loading platform 110 and achieving lightweight construction of the tooling vehicle.

[0103] Specifically, a roller 120 is provided at the lower part of the support frame 111; four beams 112 are staggered and vertically arranged in pairs on the inner side of the support frame 111, and a mounting block 113 is welded to the beam 112, and a mounting hole is opened on the mounting block 113 to form a mounting position 130. The loading platform 110 is configured as a frame structure rather than a solid plate, which ensures that the mounting position 130 is smoothly opened while reducing the weight of the tooling vehicle.

[0104] Furthermore, in this embodiment, the mounting block 113 has three shapes, namely rectangular, right-angled and "T"-shaped; among them, the rectangular mounting block 113 has four mounting positions 130, the right-angled mounting block 113 has two mounting positions 130, and the "T"-shaped mounting block 113 has three mounting positions 130.

[0105] In some embodiments, Figure 1 , Figure 4 As shown, the loading platform 110 further includes a bottom plate 114 .

[0106] The bottom plate 114 is disposed on the upper part of the support frame 111 and the mounting block 113 , and the bottom plate 114 is used to carry the part 400 ; the bottom plate 114 is provided with a plurality of through holes, and the through holes are arranged one-to-one corresponding to the mounting positions 130 , and the first limiting structure 140 is installed in the mounting position 130 through the through holes.

[0107] In the above embodiment, a bottom plate 114 is provided on the upper part of the support frame 111 and the mounting block 113 for carrying the part 400 to improve the stability of the part 400 during transportation.

[0108] Specifically, the base plate 114 is configured as a thin plate structure, the mounting block 113 is welded to the beam body 112 and is simultaneously welded to the base plate 114; the through holes on the base plate 114 are arranged one-to-one with the mounting positions 130, so that the first limiting structure 140 can pass through the through holes and be smoothly plugged and assembled with the mounting position 130.

[0109] In some embodiments, Figure 1 , Figure 2 , Figure 3 As shown, the part 400 is configured as a disc-shaped structure, and the placement area 150 formed between the plurality of first limiting structures 140 is circular.

[0110] Specifically, the tooling vehicle can transport air conditioning pipe boxes, air conditioning pipe sheets and blank discs of two different outer diameters. Figure 2 The figure shows that the tooling vehicle transports air conditioning pipe boxes and air conditioning pipe plates with outer diameters ranging from 308mm to 312mm; Figure 3 The figure shows that the tooling vehicle transports a blank disc with an outer diameter of 242 mm. The installation position 130 of the transport air conditioning pipe box and air conditioning pipe plate corresponding to the first limiting structure 140 is located outside the installation position 130 of the transport blank disc corresponding to the first limiting structure 140.

[0111] According to an embodiment of the present invention, on the other hand, a tooling vehicle positioning assembly is also provided, such as Figure 1 , Figure 6 , Figure 7 As shown, it includes: a positioning device 200 and the tooling vehicle 100 of the above embodiment.

[0112] The positioning device 200 can be fixedly arranged relative to the transfer device 500. The positioning device 200 includes a first guiding frame 210 and a second guiding frame 220 which are oppositely arranged, and a connecting frame 230 connected between the first guiding frame 210 and the second guiding frame 220. The first guiding frame 210, the second guiding frame 220 and the connecting frame 230 enclose a positioning space 240. At least one side of the load platform 110 of the tooling cart 100 in the first direction is provided with a second limiting structure 160, and the second limiting structure 160 is provided with an abutting portion that can approach or move away from the load platform 110. When the tooling cart 100 enters the positioning space 240, the abutting portion is used to abut against the first guiding frame 210 and / or the second guiding frame 220 to limit the tooling cart 100 in the first direction.

[0113] In the above embodiment, the positioning device 200 fixedly arranged relative to the transfer device 500 provides a positioning space 240 for the parking of the tooling cart 100. By using the abutting action between the abutting portion on the second limiting structure 160 that can be telescopically adjusted relative to the load platform 110 and the first guiding frame 210 and the second guiding frame 220, the tooling cart 100 is limited in the left and right directions, avoiding the left and right displacement of the tooling cart 100 when it is about to unload and transfer parts after reaching the transfer device 500, ensuring the fixed position of the tooling cart 100 itself and the parts 400 thereon, and thus guaranteeing the positioning accuracy of the parts after being transported by the tooling cart when they reach the next station.

[0114] Specifically, the positioning device 200 is fixedly arranged on the ground near the transfer device 500 by screws. The transfer device 500 includes a main structure 510, a robotic arm 520 and a ground rail 530. The robotic arm 520 is arranged on the main structure 510, and the main structure 510 is slidably arranged on the ground rail 530. After the robotic arm 520 picks up the parts 400 on the tooling cart 100, the main structure 510 slides along the ground rail 530 to transfer the parts 400 to the next station. The side of the tooling cart 100 with the handle frame 180 is defined as the rear side of the tooling cart 100, and the first direction of the tooling cart 100 is the left and right direction of the tooling cart 100. The positioning device 200 is formed by the first guiding frame 210, the second guiding frame 220 and the connecting frame 230 enclosing a "冂"-shaped overall structure, and its interior is the positioning space 240. The abutting portion of the second limiting structure 160 is a partial structure with the movable end of the second limiting structure 160 arranged outward, that is, the partial structure where the movable end of the second limiting structure 160 approaches the first guiding frame 210 and the second guiding frame 220 when the tooling cart 100 enters the positioning device 200. The abutting portion of the second limiting structure 160 can be specifically set as an arc-shaped slider for sliding cooperation with the first guiding frame 210 and the second guiding frame 220, or set as a roller member for rolling cooperation with the first guiding frame 210 and the second guiding frame 220.

[0115] Furthermore, this embodiment does not limit the specific driving mode of the abutment portion in the second limiting structure 160 to move closer to or away from the loading platform 110. As one embodiment, the abutment portion is connected to an electric drive transmission member, and the abutment portion is driven to move closer to or away from the loading platform 110 by an automated electric drive mode; as another embodiment, the abutment portion is connected to a mechanical transmission member, and the abutment portion is driven to move closer to or away from the loading platform 110 by a manual adjustment mode.

[0116] Further, the loading platform 110 of the tooling vehicle 100 is provided with a second limiting structure 160 on one side along the first direction or on both sides. When the second limiting structure 160 is provided only on one side of the loading platform 110 along the first direction, the abutting portion is used to abut against one of the first guide frame 210 and the second guide frame 220; when the second limiting structure 160 is provided on both sides of the loading platform 110 along the first direction, the two abutting portions are used to abut against the first guide frame 210 and the second guide frame 220 respectively.

[0117] Furthermore, a side of the first guide frame 210 away from the connecting frame 230 is set as a first guide end 211, and a side of the second guide frame 220 away from the connecting frame 230 is set as a second guide end 221. The first guide end 211 and the second guide end 221 form an outward expansion structure, thereby expanding the width of the entrance position of the positioning space 240 in the positioning device 200 to facilitate the tooling vehicle 100 to enter the positioning space 240; the lower parts of the first guide frame 210, the second guide frame 220 and the connecting frame 230 are connected to a bottom connecting plate 250 that is close to the ground. After the tooling vehicle 100 enters the positioning device 200, it is located on the bottom connecting plate 250, so as to avoid poor ground flatness causing positioning accuracy errors to the tooling vehicle 100 and the parts 400 thereon.

[0118] Furthermore, a ball structure may be provided on the inner side of the first guide frame 210 and the second guide frame 220 to improve the running smoothness of the tooling vehicle 100 entering the positioning device 200 .

[0119] Furthermore, the main body of the tooling vehicle 100 adopts an aluminum profile structure to achieve the purpose of lightweight.

[0120] In some embodiments, Figure 1 , Figure 4 , Figure 5 As shown, the second limiting structure 160 includes: a fixing block 161 , an adjusting block 162 and an adjusting screw 164 .

[0121] The fixed block 161 is fixedly connected to the lower part of the loading platform 110 of the tooling vehicle 100 and is located on at least one side of the loading platform 110 along the first direction; the adjusting block 162 is movably connected to the fixed block 161, and a guide wheel 163 is provided on the side of the adjusting block 162 away from the loading platform 110, and the guide wheel 163 is set as an abutment portion; the adjusting screw 164 is passed through the fixed block 161 and is transmission-connected to the adjusting block 162, and the adjusting screw 164 is used to be driven to drive the adjusting block 162 closer to or away from the loading platform 110.

[0122] In the above embodiment, mechanical adjustment of the abutment portion set as the guide wheel 163 to move closer to or away from the loading platform 110 is achieved by adjusting the screw 164 in cooperation with the fixed block 161 and the adjustment block 162; setting the abutment portion as the guide wheel 163 improves the smoothness of the operation of the tooling vehicle 100 entering the positioning device 200.

[0123] Specifically, during actual operation, the staff can change the width of the left and right sides of the tooling vehicle 100 by screwing the adjustment screw 164 to move the guide wheel 163 closer to or away from the loading platform 110, so that the width of the left and right sides of the tooling vehicle 100 matches the spacing between the first guide frame 210 and the second guide frame 220 in the positioning device 200.

[0124] In some embodiments, Figure 1 , Figure 4 , Figure 6 , Figure 8 As shown, the tooling vehicle positioning assembly further includes: a third limiting structure 300 .

[0125] The third limiting structure 300 is located on the side of the first guide frame 210 and / or the second guide frame 220 away from the connecting frame 230; after the tooling vehicle 100 enters the positioning space 240, the third limiting structure 300 can cooperate with the connecting frame 230 to limit the tooling vehicle 100 in the second direction, and the second direction is perpendicular to the first direction.

[0126] In the above embodiment, the third limiting structure 300 is used in conjunction with the connecting frame 230 to limit the tooling vehicle 100 in the front and rear directions, so as to avoid the tooling vehicle 100 from being displaced forward and backward when it arrives at the transfer equipment 500 and prepares to unload and transfer parts, thereby ensuring that the position of the tooling vehicle 100 itself and the positions of the parts 400 thereon are fixed, thereby ensuring the accuracy of the parts transported by the tooling vehicle when they arrive at the next workstation.

[0127] Specifically, the side of the tooling vehicle 100 having the handle frame 180 is defined as the rear side of the tooling vehicle 100, and the second direction of the tooling vehicle 100 is the front and rear direction of the tooling vehicle 100. After the tooling vehicle 100 enters the positioning device 200, the third limiting structure 300 limits the tooling vehicle 100 from the rear side.

[0128] Furthermore, the third limiting structure 300 is provided as one and is located on the side of the first guide frame 210 away from the connecting frame 230 or on the side of the second guide frame 220 away from the connecting frame 230; or, if the tooling vehicle 100 and the parts 400 thereon are too heavy, the third limiting structure 300 is provided as two and is located respectively on the side of the first guide frame 210 away from the connecting frame 230 and on the side of the second guide frame 220 away from the connecting frame 230, thereby applying greater force to the tooling vehicle 100 to improve the stability of the limitation.

[0129] In some embodiments, Figure 6 , Figure 8 As shown, the third limiting structure 300 includes: a driving member 310 , a rotating arm 320 and a solenoid valve 320 .

[0130] The driving member 310 has a driving end, which is communicatively connected to the solenoid valve 330 and can receive a control signal from the solenoid valve 330 to control the movement of the driving end; the rotating arm 320 is connected to the driving end, and the rotating arm 320 can be driven by the driving end to abut against at least one side of the loading platform 110 along the second direction.

[0131] In the above embodiment, the driven rotating arm 320 capable of abutting the front or rear side of the loading platform 110 cooperates with the connecting frame 230 to limit the front and rear directions of the tooling vehicle 100, thereby preventing the tooling vehicle 100 from being displaced forward and backward when it arrives at the transfer equipment 500 and prepares to unload and transfer parts.

[0132] Specifically, the solenoid valve 320 is connected to the driving member 310 for driving and controlling the driving member 310; the driving member 310 is configured as a driving cylinder, the rotating arm 320 has two ends and the middle position thereof can be rotatably arranged, one end of the rotating arm 320 is hinged to the movable rod of the driving cylinder, and the other end is provided with a contact plate; after the tooling vehicle 100 enters the positioning device 200, the movable rod of the driving cylinder extends to drive the rotating arm 320 to rotate, so that the contact plate contacts the front side or the rear side of the loading platform 110 on the tooling vehicle 100. More specifically, if the tooling vehicle 100 is pulled so that its front side preferentially enters the positioning space 240 of the positioning device 200, the rotating arm 320 is driven to rotate so that the contact plate contacts the rear side of the loading platform 110; if the tooling vehicle 100 is pushed so that its rear side preferentially enters the positioning space 240 of the positioning device 200, the rotating arm 320 is driven to rotate so that the contact plate contacts the front side of the loading platform 110. In addition, when the operator pushes and pulls the tooling vehicle 100 into the positioning space 240 of the positioning device 200 and the tooling vehicle 100 is not fully in place, the solenoid valve 320 controls the driving member 310 to promptly drive the rotating arm 320 to rotate, so that the abutting plate acts on the loading platform 110 of the tooling vehicle 100, thereby causing the tooling vehicle 100 to move in the second direction and completely enter the positioning space 240, completely restricting the position of the tooling vehicle 100 when the automated equipment, i.e., the transfer equipment 500, grabs the parts for unloading and transfer, and keeps the tooling vehicle 100 and the parts 400 thereon stationary.

[0133] Furthermore, when the solenoid valve 320 controls the drive member 310 to retract, the drive member 310 drives the rotating arm 320 to open. At this time, the abutment plate of the rotating arm 320 does not apply force to the loading platform 110 of the tooling vehicle 100, and the operator can push or pull the tooling vehicle 100 out of the positioning device 200; when the rotating arm 320 is opened, it rotates to the outer side of the first guide frame 210 or the second guide frame 220 to avoid interference with the rotating arm 320 when the tooling vehicle 100 drives out.

[0134] Furthermore, this embodiment does not limit the arrangement of the third position-limiting structure 300. As an implementation mode, the third position-limiting structure 300 is entirely arranged on the ground near the positioning device 200; as another implementation mode, the third position-limiting structure 300 is entirely arranged on the first guide frame 210 or the second guide frame 220. This embodiment adopts the second arrangement mode, in which a mounting plate 280 is arranged on the first guide frame 210, the driving member 310 is arranged as a driving cylinder, the cylinder body of the driving cylinder is hinged to the mounting plate 280, and the middle position of the rotating arm 320 is hinged to the mounting plate 280.

[0135] In some embodiments, Figure 1 , Figure 4 , Figure 6 , Figure 8As shown, the positioning device 200 is provided with a position sensor 260 , and the tooling vehicle 100 is provided with a sensing element 170 corresponding to the sensor. The sensing element 170 and the position sensor 260 are aligned and sensed to determine the position of the tooling vehicle 100 .

[0136] In the above embodiment, the position sensor 260 and the sensing element 170 are used to determine whether the tooling vehicle 100 is in place. When the tooling vehicle 100 is not in place, the position sensor 260 sends an alarm to remind the operator to stop the machine for inspection.

[0137] Specifically, the position sensor 260 is set as a travel switch located on the connecting frame 230 of the positioning device 200, and the sensing component 170 is set as a sensor contacting sheet metal located on the front side of the loading platform 110 of the tooling vehicle 100; after the rotating arm 320 rotates into place, the alignment sensing between the sensing component 170 and the position sensor 260 is the contact sensing between the sensor contacting sheet metal and the travel switch. If the sensor contacting sheet metal does not contact the travel switch, it is determined that the tooling vehicle 100 is not in place, and an alarm is issued through the position sensor 260.

[0138] Furthermore, a buffer pad 270 is provided on the connecting frame 230 of the positioning device 200 , which is used to contact the front side of the loading platform 110 of the tooling vehicle 100 and decelerate and buffer the tooling vehicle 100 .

[0139] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present application.
