Description

Technical Field

[0001] The invention belongs to the technical field of machining, and in particular relates to a clamping device for machining automobile plate parts and a use method thereof. Background Art

[0002] There are many kinds of automobile parts, including shaft parts, plate parts, etc. Among them, when processing plate parts during mechanical processing, the common method is to use auxiliary tooling such as pressing plates to press flat parts or to use ejector blocks to tighten plate parts to achieve the positioning of plate parts.

[0003] (1) A method of positioning flat plate parts by using a pressure plate, such as a thin plate part processing clamping device disclosed in the patent with authorization announcement number CN 212020031U, including a clamping base, a lower pressure plate, an upper pressure plate, and a clamping mechanism; when in use, first pass the lower pressure plate through the positioning pin for positioning, place the thin plate part on the lower pressure plate, pass the upper pressure plate through the positioning pin for positioning, rotate the pressure rod to clamp the upper pressure plate, and the thin plate part is clamped and positioned. However, there are still the following problems: because the pressure plate is pressed on the end face of the flat plate part, when the entire end face of the flat plate part needs to be processed, it is necessary to loosen the pressure plate, change the position of the pressure plate on the end face of the flat plate part, and then re-tighten the pressure plate to continue processing, which requires multiple clamping and alignment, which is easy to affect the precision of the flatness and roughness of the processed end face, and reduce work efficiency.

[0004] (2) If the auxiliary tooling such as a pressure plate that contacts the end face of the flat plate part and presses the flat plate part downward is not used, and the tooling such as a clamping block that contacts the side face of the flat plate part and presses the flat plate part from the side is used instead, because the flat plate part only has a force to press from the side and lacks a downward force, it is easy for the flat plate part to tilt on one side due to the cutting force of the tool during the end face processing, resulting in the inability to position the flat plate part, which easily affects the processing accuracy. Moreover, the current method of clamping with a clamping block mostly adopts the method of setting bolts. For example, the patent CN 203792045U discloses a quick clamping mechanism for large-sized thin plate parts, which is provided with an adjusting bolt. By adjusting the adjusting bolt, the extension and contraction of the force adjustment slider in the groove is controlled, thereby driving the movable stopper to move and adjusting the clamping force of the workpiece. It only sets bolts on one side for support, and the clamping force is not stable enough; if bolts are set on multiple sides for support, each bolt needs to be screwed separately, which is not very convenient in operation.

[0005] Based on this, how to effectively combine and improve the two methods, and how to facilitate the operation of the staff while forming a stable clamp, is what the personnel in this field need to further consider. Summary of the invention

[0011] Preferably, the driving mechanism comprises a side plate fixedly connected to the top of the base, an adjusting bolt is threadedly connected to the side plate, and the adjusting bolt is rotatably connected to the end of the first sliding rod.

[0012] Preferably, the driving mechanism includes a side plate fixedly connected to the top of the base, a first support rod is hinged on one side of the side plate, a second support rod is hinged on the first sliding rod, a left end of the second support rod is hinged to the right end of the first support rod and a connecting rod is hinged at the hinge point at the same time; a compensation seat is slidably connected to the base, a handle is hinged on the top of the compensation seat, the handle is provided with a strip hole, a shaft rod is movably inserted in the strip hole, and the other end of the connecting rod is hinged to the shaft rod; a stop block for limiting the driving mechanism is also connected to the base.

[0013] Preferably, the surfaces of the left top pressure head, the front top pressure head and the upper top pressure head are all provided with flexible pads.

[0014] The present invention provides a method for using a clamping device for processing automobile plate parts, comprising the following steps:

[0015] Step 1: placing the plate-like parts to be processed on the base so that the two sides of the plate-like parts are respectively positioned on the rear stopper and the right stopper;

[0016] The second step is to operate the driving mechanism to drive the first sliding bar to move right, thereby realizing the right movement of the left top pressure head; when the first sliding bar moves to the right, the first rack on the first sliding bar also moves to the right with the first sliding bar, and the right movement of the first rack will drive the first gear to rotate, and the rotation of the first gear will drive the Y-axis rotating shaft to rotate, and when the Y-axis rotating shaft rotates, it will drive the active bevel gear to rotate, and then drive the driven bevel gear to rotate, and the rotation of the driven bevel gear will then drive the X-axis rotating shaft to rotate; when the X-axis rotating shaft rotates, it will drive the second gear to rotate, and the rotation of the second gear will then drive the second rack to move, and then drive and move with the second sliding bar, thereby realizing the backward movement of the front top pressure head; as the driving mechanism continues to be operated, the left top pressure head links the front top pressure head to press to the left side and front side of the plate-like parts respectively, and cooperates with the rear stopper and the right stopper to limit the rear side and right side of the plate-like parts, so that the four sides of the plate-like parts are tightly pressed, and the clamping and fixing of the plate-like parts are completed.

[0017] Preferably, the above step 2 also includes pressing the plate-like parts upward, and the specific method is as follows:

[0018] When the X-axis rotates, the active bevel gear sleeved on the X-axis rotates also rotates, and then drives the driven bevel gear to rotate. The rotation of the driven bevel gear drives the worm to rotate, and the rotation of the worm drives the worm wheel to rotate. Since the inside of the worm wheel is threadedly connected with the threaded rod, when the worm wheel rotates, it drives the threaded rod to move downward under the guidance of the guide block, so that the upper pressure head is pressed on the upper surface of the plate part, and the pressing and fixing in the Z-axis direction is achieved.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The present invention adopts a four-side pressing method, wherein the rear side and right side of the plate-like parts are limited by a "fixed" rear stopper and a right stopper, and the front side and left side of the plate-like parts are limited by a "movable" side pressing assembly, and the left pressing head and the front pressing head in the side pressing assembly can also be linked through a transmission mechanism, so that the staff can operate more conveniently. Only the driving mechanism on the left side needs to be controlled to achieve the clamping and fixing of the plate-like parts on the left and the front side at the same time. The structure is simple, the operation is convenient, and the efficiency is improved.

[0021] 2. The present invention also provides an upper pressing assembly, which mainly adopts a worm gear mechanism linked with a transmission mechanism, and the worm wheel has threads inside, which can be threadedly connected with the threaded rod. When the worm wheel rotates, it can drive the threaded rod to move up and down, thereby facilitating the pressing and fixing of the upper surface of the plate parts. The upper pressing assembly and the side pressing assembly are driven in linkage with each other by the same driving mechanism. The staff only needs to operate the driving mechanism to achieve the perfect linkage between the side pressing assembly and the upper pressing assembly. It is very convenient to use. Without increasing the extra workload, the two methods of side pressure and top pressure can be effectively combined, thereby greatly improving the work efficiency.

[0022] 3. The driving mechanism of the present invention adopts two methods. One is the method of adopting an adjusting bolt, and the movement of the first sliding rod is achieved by screwing the adjusting bolt, thereby linking other subsequent structures; the second is the method of adopting a hand-pull handle. In this method, the driving mechanism adopts a Y-shaped structure formed by a first support rod, a second support rod and a connecting rod. By pulling the handle, the angle of the Y-shaped structure is changed to achieve the pushing of the first sliding rod. The hand-pull structure has the advantages of fast clamping and convenient operation. In addition, a stop block is also provided in this method. When the handle is pulled, the angle of the Y-shaped structure will become larger, and the angle between the first support rod and the second support rod is greater than 180 degrees. Due to the limiting effect of the stop block, the first sliding block cannot move to the left after being pressed, so the driving mechanism cooperates with the stop block to form self-locking, prevent retreat, and maintain stable clamping. Using this driving method, you only need to push the handle to lock the plate parts from three directions at the same time, reducing the cumbersome steps of adjusting bolts in different directions, reducing the clamping process, and improving the clamping efficiency.

DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] like Figure 1-7 As shown, this embodiment proposes a clamping device for processing automobile plate parts, including a rectangular base 1, the base 1 is used as a processing platform, and two adjacent sides of the base 1 are respectively connected with a rear stopper 4 and a right stopper 5 for limiting the two sides of the plate parts. The rear stopper 4 and the right stopper 5 are used as fixed limit stops, which can be directly fixedly connected to the base 1 by welding.

[0035] The base 1 is also provided with a side pressing assembly for limiting the remaining two side edges of the plate-like parts; the side pressing assembly includes a left fixed block 9 and a front fixed block 10 respectively connected to the base 1; the left fixed block 9 is slidably connected with a first slide bar 7, and the first slide bar 7 can slide left and right along the left fixed block 9; one side of the first slide bar 7 is connected to a driving mechanism for driving the first slide bar 7 to slide, and the sliding of the first slide bar 7 can be achieved by operating the driving mechanism; the other end of the first slide bar 7 is connected to a left pressing head 71, which is used to support the left end of the plate-like parts to be processed to achieve tight fixing on the left side.

[0036] A second slide bar 18 is slidably connected to the front fixed block 10, and the second slide bar 18 can slide back and forth along the front fixed block 10. One end of the second slide bar 18 is connected to a front pressing head 181, which is used to support the front end of the plate part to achieve tightening and fixing; the first slide bar 7 is connected to the second slide bar 18 through a transmission mechanism, which is used to drive the second slide bar 18 to slide in a linked manner.

[0037] It can be seen that the technical solution adopts a four-side pressing method, in which the rear side and right side of the plate parts are limited by a "fixed" rear stopper 4 and a right stopper 5, and the front side and left side of the plate parts are limited by a "movable" side pressing assembly, and the left pressing head 71 and the front pressing head 181 in the side pressing assembly can also be linked through a transmission mechanism, making it more convenient for the staff to operate. Only the driving mechanism on the left side needs to be controlled to achieve the clamping and fixing of the plate parts on the left and the front side at the same time. The structure is simple, the operation is convenient, and the efficiency is improved.

[0038] The transmission mechanism described above is described in detail below:

[0039] The transmission mechanism includes a first rack 6, which is fixedly connected to the first slide bar 7 and can move with the first slide bar 7; the top of the base 1 is rotatably connected to a Y-axis shaft 23, and the Y-axis shaft 23 can rotate freely relative to the base 1; one end of the Y-axis shaft 23 is sleeved and connected to a first gear 8, and the first gear 8 is meshed with the first rack 6. When the first rack 6 moves, it drives the first gear 8 to rotate, thereby driving the Y-axis shaft 23 to rotate; the other end of the Y-axis shaft 23 is connected to an active bevel gear 13; the base 1 is also rotatably connected to an X-axis shaft 12, The X-axis rotating shaft 12 can also rotate freely relative to the base 1; one end of the X-axis rotating shaft 12 is connected to the driven bevel gear 11 meshing with the active bevel gear 13; the second slide bar 18 is connected to the second rack 19, and the second rack 19 is meshed with the second gear 26, and the second gear 26 is sleeved and connected to the other end of the X-axis rotating shaft 12. When the X-axis rotating shaft 12 rotates, it will drive the second gear 26 to rotate. The rotation of the second gear 26 can drive the second rack 19 to move, and then drive the second slide bar 18 to move, so that the front pressing head 181 presses on the front side of the plate part.

[0040] As a feasible solution, there are many options for the selection of the driving mechanism, for example, an electric push rod structure can be used, the piston rod of the electric push rod is connected to the first slide rod 7, and the first slide rod 7 can be driven to move left and right by the extension of the electric push rod; of course, a manual drive method can also be used, for example, an adjusting bolt structure is used, which includes a side plate 102 fixedly connected to the top of the base 1, and an adjusting bolt is threadedly connected to the side plate 102. The adjusting bolt is rotatably connected to the end of the first slide rod 7. When the adjusting bolt is rotated, the first slide rod 7 can be driven to move. Of course, a hand lever drive method can also be used, and its specific structure can be as follows:

[0041] The driving mechanism includes a side plate 102 fixedly connected to the top of the base 1, a first support rod 2 is hinged on one side of the side plate 102, a second support rod 3 is hinged on the first sliding rod 7, the left end of the second support rod 3 is hinged to the right end of the first support rod 2 and the hinge point is also hinged to the connecting rod 21; a compensation seat 202 is slidably connected to the base 1, the compensation seat 202 can move along the base 1, and a dovetail groove and a dovetail cam can be used between the compensation seat 202 and the base 1; a handle 20 is hinged on the top of the compensation seat 202, and the handle 20 is provided with a strip hole 201, and a shaft rod is movably inserted in the strip hole 201, and the shaft rod can move along the strip hole 201; the other end of the connecting rod 21 is hinged to the shaft rod; a stop block 22 for limiting the driving mechanism is also connected to the base 1.

[0042] It should be noted that the driving mechanism in the above method adopts a Y-shaped structure formed by the first support rod 2, the second support rod 3 and the connecting rod 21. By turning the handle 20, the angle of the Y-shaped structure is changed to realize the pushing of the first sliding rod 7. The hand-pull structure has the advantages of quick clamping and convenient operation. In addition, this method also has a stop block 22. When the handle 20 is turned, the angle of the Y-shaped structure will become larger, and the angle between the first support rod 2 and the second support rod 3 is greater than 180 degrees. Due to the limiting effect of the stop block 22, the first sliding block cannot move to the left after being pressed. Therefore, the driving mechanism cooperates with the stop block 22 to form self-locking, prevent retreat, and maintain stable clamping. Using this driving method, you only need to push the handle to lock the plate parts from three directions at the same time, which reduces the cumbersome steps of adjusting bolts in different directions, reduces the clamping process, and improves the clamping efficiency.

[0043] As a preferred solution, on the basis of the side pressing assembly, the whole device also includes an upper pressing assembly, which includes a vertically arranged sliding cavity 101, which is opened at corresponding positions of the front fixing block 10 and the base 1; wherein the sliding cavity 101 runs through the entire front fixing seat; a threaded rod 17 that can be lifted up and down is slidably connected in the sliding cavity 101; the threaded rod 17 can move up and down in the sliding cavity 101; a worm gear 15 that is connected to the front fixing block 10 for relative rotation is also provided in the sliding cavity 101, the worm gear 15 is connected to the front fixing block 10 for rotation through a bearing, a threaded hole is opened in the center of the worm gear 15, and the threaded rod 17 is threadedly connected to the threaded hole; the sliding cavity 1 01 is also provided with a guide block 16, and a guide groove 1701 is opened vertically on the threaded rod 17. One end of the guide block 16 is connected to the front fixed block 10, and the other end is inserted into the guide groove 1701, which plays a role of anti-rotation and guiding; the front fixed block 10 is also rotatably connected with a worm 14, and the worm 14 can rotate freely; the worm 14 is matched and connected with the worm wheel 15; a driven bevel gear 24 is sleeved and connected on the worm 14; an active bevel gear 25 is also connected to the X-axis rotating shaft 12, and the active bevel gear 25 is meshed with the driven bevel gear 24; a support arm 171 is fixedly connected to the top of the threaded rod 17, and the other end of the support arm 171 is connected to an upper pressure head 1711.

[0044] The upper pressing assembly mentioned above mainly adopts a worm gear 15 and a worm 14 mechanism linked with a transmission mechanism, and the worm gear 15 has a thread inside, which can be threadedly connected with a threaded rod 17. When the worm gear 15 rotates, it can drive the threaded rod 17 to move up and down, thereby facilitating the pressing and fixing of the upper surface of the plate parts. The upper pressing assembly and the side pressing assembly are driven in linkage with each other by the same driving mechanism. The staff only needs to operate the driving mechanism to achieve the perfect linkage between the side pressing assembly and the upper pressing assembly. It is very convenient to use. Without increasing the extra workload, the two methods of side pressure and top pressure can be effectively combined, which greatly improves the work efficiency.

[0045] As a preferred technical solution, the surfaces of the left top pressure head 71, the front top pressure head 181 and the upper top pressure head 1711 are all provided with flexible pads (not shown in the figure), and the rear block 4 and the right block 5 also have flexible pads to provide protection and displacement compensation.

[0046] The present invention provides a method for using a clamping device for processing automobile plate parts, comprising the following steps:

[0047] Step 1: Place the plate-like part to be processed on the base 1 so that the two sides of the plate-like part are respectively positioned on the rear stopper 4 and the right stopper 5;

[0048] Step 2: Operate the driving mechanism to drive the first slide bar 7 to move right, thereby realizing the right movement of the left top pressure head 71; when the first slide bar 7 moves right, the first rack 6 on the first slide bar 7 also moves right with the first slide bar 7, and the right movement of the first rack 6 drives the first gear 8 to rotate, and the rotation of the first gear 8 drives the Y-axis rotating shaft 23 to rotate, and the rotation of the Y-axis rotating shaft 23 drives the active bevel gear 13 to rotate, and then drives the driven bevel gear 11 to rotate, and the rotation of the driven bevel gear 11 drives the X-axis rotating shaft 12 to rotate; the X-axis rotating shaft When the shaft 12 rotates, it will drive the second gear 26 to rotate. The rotation of the second gear 26 will in turn drive the second rack 19 to move, and then drive the second slide bar 18 to move, so that the front top pressure head 181 moves backward; as the driving mechanism continues to be manipulated, the left top pressure head 71 links the front top pressure head 181 to press to the left side and front side of the plate-like parts respectively, and cooperate with the rear stop block 4 and the right stop block 5 to limit the rear side and right side of the plate-like parts, so that the four sides of the plate-like parts are tightly pressed, completing the clamping and fixation of the plate-like parts.

[0049] Step 2 also includes pressing the plate parts upward, and the specific method is as follows:

[0050] When the X-axis rotating shaft 12 rotates, the active bevel gear 25 sleeved on the X-axis rotating shaft 12 will also rotate, thereby driving the driven bevel gear 24 to rotate. The rotation of the driven bevel gear 24 will drive the worm 14 to rotate, and the rotation of the worm 14 will drive the worm wheel 15 to rotate. Since the inside of the worm wheel 15 is threadedly connected with the threaded rod 17, the worm wheel 15 will drive the threaded rod 17 to move downward under the guidance of the guide block 16 when rotating, so that the upper pressure head 1711 is pressed against the upper surface of the plate part, and the pressing and fixing in the Z-axis direction is achieved.

[0051] It should be noted that when the driving mechanism in step 2 adopts the structure of the handle 20, the specific method is as follows:

[0052] In the initial state, the Y-shaped structure formed by the first support rod 2, the second support rod 3 and the connecting rod 21, the angle formed between the first support rod 2 and the second support rod 3 is recorded as α, and α is an acute angle; when in use, by pulling the handle 20, the handle 20 drives the connecting rod 21 to move, and the movement of the connecting rod 21 will change the angle of the Y-shaped structure, and the angle α will change to realize the pushing of the first slide bar 7. When α becomes a flat angle, a straight line is formed between the first support rod 2 and the second support rod 3, and the displacement of the first slide bar 7 is the largest. Continue to pull the handle 20, and the angle α changes from a flat angle to an excellent angle until it is supported on the stop block 22; in the process of α changing from a flat angle to an excellent angle, the distance of the vector line formed between the two end points of the first support rod 2 and the second support rod 3 becomes shorter, and the first slide bar 7 retreats slightly. This part of the retreat displacement is compensated by the flexible pads on each top pressure block to ensure that the stop block 22 can form a self-locking.

[0053] The present method adopts a hand-pull structure, which has the advantages of quick clamping and convenient operation. In addition, the present method also has a stop block 22. When the handle 20 is pulled, the angle of the Y-shaped structure will become larger, and the angle between the first support rod 2 and the second support rod 3 will be greater than 180 degrees. Due to the limiting effect of the stop block 22, the first slider cannot move to the left after being pressed. Therefore, the drive mechanism cooperates with the stop block 22 to form a self-locking function to prevent retreat and maintain stable clamping.

[0054] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.

A method for using a clamping device for processing automobile plate parts, characterized in that: The clamping device for processing automobile plate parts according to any one of claims 2 to 5 comprises the following steps: Step 1: placing the plate-like parts to be processed on the base so that the two sides of the plate-like parts are respectively positioned on the rear stopper and the right stopper; The second step is to operate the driving mechanism to drive the first sliding bar to move right, thereby realizing the right movement of the left top pressure head; when the first sliding bar moves to the right, the first rack on the first sliding bar also moves to the right with the first sliding bar, and the right movement of the first rack will drive the first gear to rotate, and the rotation of the first gear will drive the Y-axis rotating shaft to rotate, and when the Y-axis rotating shaft rotates, it will drive the active bevel gear to rotate, and then drive the driven bevel gear to rotate, and the rotation of the driven bevel gear will then drive the X-axis rotating shaft to rotate; when the X-axis rotating shaft rotates, it will drive the second gear to rotate, and the rotation of the second gear will then drive the second rack to move, and then drive and move with the second sliding bar, thereby realizing the backward movement of the front top pressure head; as the driving mechanism continues to be operated, the left top pressure head links the front top pressure head to press to the left side and front side of the plate-like parts respectively, and cooperates with the rear stopper and the right stopper to limit the rear side and right side of the plate-like parts, so that the four sides of the plate-like parts are tightly pressed, and the clamping and fixing of the plate-like parts are completed.

7. The method for using the clamping device for processing automobile plate parts according to claim 6, characterized in that: The above step 2 also includes pressing the plate parts upward, and the specific method is as follows: When the X-axis rotates, the active bevel gear sleeved on the X-axis rotates also rotates, and then drives the driven bevel gear to rotate. The rotation of the driven bevel gear drives the worm to rotate, and the rotation of the worm drives the worm wheel to rotate. Since the inside of the worm wheel is threadedly connected with the threaded rod, when the worm wheel rotates, it drives the threaded rod to move downward under the guidance of the guide block, so that the upper pressure head is pressed on the upper surface of the plate part, and the pressing and fixing in the Z-axis direction is achieved.
