Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, and in particular relates to an improvement of a fork arm clamp. Background Art

[0002] The fork arm is part of the vehicle's suspension system, connecting the wheels to the body. It works alongside elastic and shock-absorbing components to provide support for the entire vehicle. It impacts the vehicle's stability and reliability during movement, and ultimately, the safety of the occupants.

[0003] Therefore, it is very important to detect and measure the dimensional parameters of the processed rear fork arm.

[0075] In some embodiments of the present application, a fork arm 100 clamp is provided, and the fork arm 100 clamp cooperates with an adaptive positioning structure provided on the fork arm 100 to ensure accurate and firm clamping and positioning of the fork arm 100.

[0076] The fork arm 100 includes a columnar body 110 having a positioning end surface 111 and a side positioning platform 112 .

[0077] The positioning end surface 111 facilitates abutment and positioning.

[0078] The side positioning platform 112 is convenient for the positioning piece to rest against it for positioning, which can ensure that no sliding occurs during the positioning process and ensure the firmness of the positioning in cooperation with the positioning piece.

[0079] The fork arm 100 has two legs, a first leg 120 and a second leg 130 , which are connected in parallel to the columnar body 110 . The two legs have different heights, and the first leg 120 is higher than the second leg 130 .

[0080] The first leg 120 is provided with a first supporting boss 121 near the bottom end of the columnar body 110. The first supporting boss 121 facilitates supporting the first leg 120 so that the part supporting the first leg 120 is not a smooth curved surface when in contact with the first support, thereby ensuring that it can be stably supported.

[0081] The end of the first leg 120 is connected to a first column 122 . The first column 122 has a second supporting boss 123 at its bottom, a first positioning boss 124 at its end, and a first positioning surface 125 on its side.

[0082] The second supporting leg boss on the first column 122 facilitates supporting the first supporting leg 120 , and the first positioning boss 124 and the first positioning surface 125 facilitate positioning the first supporting leg 120 .

[0083] The second leg 130 has a second positioning surface 131 on its side, and a third supporting boss 132 is provided near the bottom end of the columnar body 110 .

[0084] The third supporting boss 132 facilitates supporting one end of the second supporting leg 130 to prevent the second supporting leg 130 from sliding.

[0085] The end of the second leg 130 is connected to a second column 133 . The second column 133 has a fourth supporting boss 134 at its bottom and a second positioning platform 135 at its end.

[0086] The fourth supporting boss 134 facilitates supporting the other end of the second supporting leg 130 , and the second positioning platform 135 at the end thereof facilitates positioning the second supporting leg 130 .

[0087] The fork arm 100 fixture is a fixture adapted to the fork arm 100 component. It is provided with a corresponding positioning structure according to the structural matching of the fork arm 100 component to ensure accurate positioning of the fork arm 100 component.

[0088] In some embodiments of the present application, the fork arm 100 clamp includes:

[0089] There are two groups of support assemblies, each group includes two support components 210 , and the two groups of support assemblies are symmetrically arranged with a distance therebetween, and are used to support the fork arm 100 through the support assemblies.

[0090] One group of two supporting components 210 is respectively arranged below the first supporting boss 121 and the second supporting boss 123 of the first leg 120 for supporting the first leg 120 .

[0091] The two supporting components 210 are located below the first supporting boss 121 and the second supporting boss 123 , and can provide bearing support for both ends of the first leg 120 .

[0092] The other two supporting components 210 are respectively arranged below the third supporting boss 132 and the fourth supporting boss 134 of the second leg 130 to support the second leg 130 .

[0093] The two supporting components 210 are located below the third supporting boss 132 and the fourth supporting boss 134 , and can provide load-bearing support for both ends of the second leg 130 .

[0094] By providing the four supporting components 210 , uniform support is achieved for the four positions of the fork arm 100 , ensuring the supporting effect for the entire fork arm 100 .

[0095] The fixture for the fork arm 100 further includes: a positioning component, which is used to position the fork arm 100 to ensure that the fork arm 100 does not shake during the measurement process, thereby ensuring the accuracy of the measurement.

[0096] The positioning component includes:

[0097] a first positioning member 220;

[0098] The second positioning member 230 is disposed opposite to the first positioning member 220 . A clamping space is formed between the second positioning member 230 and the first positioning member 220 , and the fork arm 100 is disposed in the clamping space.

[0099] The columnar body 110 of the fork arm 100 in the clamping space faces the first positioning member 220 , and the first and second columns 122 and 133 at the ends of the first and second legs 120 and 130 face the second positioning member 230 .

[0100] The positioning drive member 240 is connected to the first positioning member 220 and the second positioning member 230 respectively, driving the first positioning member 220 and the second positioning member 230 to move toward each other so that the first positioning member 220 is pressed against the positioning end face 111, and the second positioning member 230 is pressed against the first positioning platform and the second positioning platform 135 to clamp and fix the fork arm 100 in the first direction.

[0101] When the fork arm 100 is placed on the support assembly, the positioning drive member 240 can be activated to drive the first positioning member 220 and the second positioning member 230 to move toward each other, so as to press the fork arm 100 against the positioning end surface 111 and the first positioning platform and the second positioning platform 135 in the first direction respectively.

[0102] The positioning assembly further includes a third positioning member 250 and a fourth positioning member 260 , through which the third positioning member 250 , the fourth positioning member 260 and the side extension 211 on the support member 210 on the same side as the fourth positioning member 260 can achieve positioning of the fork arm 100 in the second direction.

[0103] Specifically, the third positioning member 250 is arranged on the side of the second leg 130 and is used to press on the second positioning surface 131 of the second leg 130. It is movable along the second direction. The third positioning member 250 can adjust the clamping degree of the fork arm 100 by moving along the second direction, wherein the second direction is perpendicular to the first direction.

[0104] The fourth positioning member 260 is arranged on the side of the first leg 120 and is opposite to the third positioning member 250 .

[0105] The fourth positioning member 260 is connected to the support component 210 supporting the first leg 120 and close to the columnar body 110 , and is used to abut against the side positioning platform 112 . The distance between the fourth positioning member 260 and the side support platform is adjustable.

[0106] The fourth positioning member 260 can abut against the side positioning platform 112 of the columnar body 110 to limit the position of the columnar body 110;

[0107] A side extension portion 211 is formed on the side of the support component 210 below the first column 122 and extends upward. The side extension portion 211 abuts against the first positioning surface 125 . The side extension portion 211 and the fourth positioning member 260 are arranged on the same side of the first leg 120 .

[0108] The side extension portion 211 formed on the support component 210 can abut against the first positioning surface 125 of the first column 122 on the opposite side of the third positioning member 250, and it and the fourth positioning member 260 respectively abut against the two end positions of the fork arm 100 on the side of the first leg 120, and cooperate with the third positioning member 250 to apply a force in the opposite direction to the fork arm 100, so as to position and fix the fork arm 100 in the second direction.

[0109] When positioning the fork arm 100, first place the fork arm 100 on the support assembly, then drive the first positioning member 220 and the second positioning member 230 to move through the positioning drive member 240 to position the fork arm 100 in the first direction, move the third positioning member 250, and cooperate with the fourth positioning member 260 and the side extension portion 211 to clamp and position the fork arm 100 in the second direction. The positioning of the fork arm 100 by the entire clamp is achieved through the automatic action of the first positioning member 220, the second positioning member 230 and the third positioning member 250, thereby realizing automatic clamping or loosening of the fork arm 100.

[0110] In this embodiment, the fork arm 100 fixture is provided with a support assembly that matches the first support boss 121 , the second support boss 123 , the third support boss 132 , and the fourth support boss 134 arranged correspondingly on the fork arm 100 to support the fork arm 100 ;

[0111] The first positioning member 220 and the second positioning member 230 are configured to move and cooperate with the positioning end surface 111 of the fork arm 100 and the first positioning boss 124 and the second positioning boss to press and position the fork arm 100 in the first direction;

[0112] The third positioning member 250, the fourth positioning member 260 and the side extension 211 cooperate with the second positioning surface 131, the first positioning surface 125 and the side positioning platform 112 on the fork arm 100 to position the fork arm 100 in the second direction.

[0113] The support components and positioning components are matched with the corresponding positioning bosses or support bosses on the fork arm 100 to position the fork arm 100, thereby achieving precise matching and positioning of the fork arm 100, with high positioning accuracy and good positioning effect.

[0114] In the fork arm 100 fixture of this embodiment, after positioning is completed, the first positioning member 220 and the second positioning member 230 are arranged at the two ends of the fork arm 100, the third positioning member 250 and the fourth positioning member 260 are located on both sides of the fork arm 100, and the support assembly is at the bottom of the fork arm 100. Both the support assembly and the positioning assembly are arranged around the fork arm 100, and neither of them blocks the top contour of the fork arm 100. The corresponding contour dimensions of the fork arm 100 and the dimensional parameters of the first column 122 or the first supporting leg, as well as parameters such as flatness or roughness, can be conveniently measured, thereby ensuring accurate measurement of the fork arm 100.

[0115] In the fork arm 100 clamp of this embodiment, the first positioning member 220 and the second positioning member 230 can be driven to move by the positioning driving member 240 to realize automatic opening and closing, and the third positioning member 250 is also movable. When the robot grasps the fork arm 100, the first positioning member 220, the second positioning member 230 and the third positioning member 250 can be automatically moved and opened to conveniently pick up the fork arm 100, which facilitates the robot to perform the picking operation.

[0116] In some embodiments of the present application, the fork arm 100 clamp further includes:

[0117] A detection component, the detection component includes: a photoelectric reflector 270, the height of the photoelectric reflector 270 is similar to that of the first leg 120;

[0118] And a photoelectric switch 280 is arranged opposite to the photoelectric reflector 270. The photoelectric switch 280 has a transmitting end and a receiving end. The transmitting end is used to transmit light to the photoelectric reflector 270, and the receiving end is used to receive the light reflected by the photoelectric reflector 270. A detection space is formed between the photoelectric switch 280 and the photoelectric reflector 270.

[0119] When the first leg 120 is placed in the detection space, the first leg 120 blocks the photoelectric reflector 270, and the photoelectric switch 280 cannot receive the reflected light from the photoelectric reflector 270;

[0120] When the leg at the detection space is the second leg 130 or there is no leg, the photoelectric switch 280 receives the light emitted by the photoelectric reflector 270 .

[0121] The detection component can be used to detect whether there is a fork arm 100 part in the detection space.

[0122] When there is a fork arm 100 part in the detection space and the part is positioned correctly, the light emitted by the transmitting end of the photoelectric switch 280 will be blocked by the first leg 120 of the fork arm 100. At this time, it cannot receive the reflected light from the photoelectric reflector 270.

[0123] When there is no part in the detection space, the light emitted by the transmitting end of the photoelectric switch 280 will not be blocked. At this time, it receives the reflected light from the photoelectric reflector 270, which means that the part is placed incorrectly.

[0124] The detection component can also be used to detect whether the fork arm 100 is anti-reverse. In the normal placement state, the first leg 120 is in the detection space between the photoelectric reflector 270 and the photoelectric switch 280. At this time, since the photoelectric reflector 270 and the first leg 120 are at similar heights, the first leg 120 will block the photoelectric reflector 270 after being placed in place. At this time, the photoelectric switch 280 cannot receive any signal, and it is determined that the fork arm 100 is not reversed.

[0125] On the contrary, if the fork arm 100 is placed upside down, the second leg 130 will be in the detection space. Since the second leg 130 is lower than the first leg 120, it will not block the photoelectric reflector 270, so that the photoelectric switch 280 can receive the light from the photoelectric reflector 270.

[0126] In some embodiments of the present application, the positioning drive member 240 is a bidirectional clamping cylinder including a first moving claw, to which the first positioning member 220 is connected, and a first positioning stop portion is formed on the first positioning member 220.

[0127] The first positioning and retaining portion is a first positioning and retaining protrusion formed on the first positioning member 220 or a first positioning block fixed at the end of the first positioning member 220 . The first positioning block is arranged perpendicular to the first positioning member 220 .

[0128] The first positioning retaining portion is used to retain on the positioning end surface 111 .

[0129] And a second moving claw is arranged opposite to the first moving claw, a second positioning member 230 is connected to the second moving claw, and a second positioning resisting portion is formed on the second positioning member 230.

[0130] The second positioning and retaining portion is a second positioning and retaining protrusion formed on the second positioning member 230 or a second positioning block fixed at the end of the second positioning member 230 , and the second positioning block is arranged perpendicular to the second positioning member 230 .

[0131] In some embodiments of the present application, the support component 210 includes:

[0132] A support body 212 having a mounting portion 2121 formed on the top of the support body 212;

[0133] The rigid support member 213 is detachably assembled on the top mounting portion 2121 .

[0134] The support body 212 is a support block, and the mounting portion 2121 is a mounting notch formed on the top of the support body 212 . The shape of the mounting notch matches that of the rigid support member 213 .

[0135] The rigid support member 213 can be fixed to the support body 212 by means of countersunk screws. The rigid support member 213 is located at the top of the support body 212 and is used to directly contact the fork arm 100 to support it.

[0136] The rigid support member 213 is made of carbon steel, which has high strength and good wear resistance, and can ensure that it is not easily damaged even after long-term use.

[0137] When the rigid support member 213 is worn and damaged, it can be removed and replaced separately without replacing the entire support component 210, thereby reducing production costs.

[0138] In some embodiments of the present application, the third positioning member 250 includes a third driving cylinder 251 and a third connecting block 252 connected to the third driving cylinder 251, and a third clamping block 253 is connected to the third connecting block 252, and the third clamping block 253 has a clamping plane 254.

[0139] The third clamping block 253 is locked and fixed on the third connecting block 252. When the third driving cylinder 251 is actuated, the third clamping block 253 can be driven to actuate. The third clamping block 253 presses the second positioning surface 131 of the second leg 130 through the clamping plane 254 above it.

[0140] In order to prevent the third pressing block 253 from damaging the fork arm 100 due to hard contact with the second leg 130, nylon is selected as its material, which ensures that it has sufficient strength to achieve a good pressing effect and can ensure that the fork arm 100 will not be damaged.

[0141] In some embodiments of the present application, the fourth positioning member 260 includes: a fourth connecting block 261 connected to the supporting member 210 near the columnar body 110 and arranged opposite to the third positioning member 250;

[0142] The fourth abutting member 262 is screwed into the fourth connecting block 261 and is disposed perpendicular to the side surface of the columnar body 110 . A side abutting platform is formed at the end thereof to abut against the side positioning platform 112 .

[0143] The fourth abutting member 262 is a fourth abutting bolt, which can abut against the side support platform to position the fork arm 100 .

[0144] When the position of the fourth positioning member 260 needs to be adjusted, the fourth clamping member 262 can be screwed relative to the fourth connecting block 261 so that the fourth clamping member 262 moves along the side direction of the vertical columnar body 110 to change its position, thereby changing the degree of compression on the columnar body 110 and ensuring that the columnar body 110 is appropriately compressed.

[0145] In some embodiments of the present application, the fork arm 100 fixture further includes a first base 300;

[0146] The second base 400 is arranged parallel to the first base 300 , and the supporting assembly, positioning assembly and detection assembly are all assembled on the second base 400 .

[0147] The lifting assembly is assembled on the first base 300 and connected to the second base 400 to drive the second base 400 to move up and down.

[0148] The first base 300 is a first substrate, and the second base 400 is a second substrate, which are arranged parallel to the first substrate.

[0149] The lifting assembly can drive the fork arm 100 clamp mounted thereon to move up and down by driving the second substrate to move up and down relative to the first substrate, thereby making the fork arm 100 clamp height adjustable to adapt to clamping occasions of different heights.

[0150] In some embodiments of the present application, the lifting assembly 510 includes:

[0151] The main lifting cylinder 517 has a main cylinder rod, and the end of the main cylinder rod is connected to the cylinder frame.

[0152] The movement of the main cylinder rod can drive the cylinder frame connected to it to move in extension and contraction.

[0153] In some embodiments of the present application, the lifting assembly includes a lifting link, and the lifting link includes:

[0154] There are two first connecting rods 511 , which are symmetrically arranged.

[0155] There are two second connecting rods 512 , which are symmetrically arranged.

[0156] The first hinge shaft 513 is hinged to one end of the two first connecting rods 511 and the second base 400 .

[0157] Specifically, one end of the first hinge shaft 513 passes through one end of one of the first connecting rods 511 and is connected to the first connecting rod 511 through a bearing. The section extending out of the first connecting rod 511 is connected to the second base 400 through a bearing assembly.

[0158] The other end of the first hinge shaft 513 passes through one end of the other first connecting rod 511 and is rotatably connected to the other first connecting rod 511 through a bearing. The section extending out of the other first connecting rod 511 is connected to the second base 400 through a bearing assembly.

[0159] The bearing assembly includes a bearing and a bearing seat. The bearing is connected to the first hinge shaft 513 , and the bearing seat is connected to the second base 400 to achieve hinge connection between the first hinge shaft 513 and the second base 400 .

[0160] The second hinge shaft 514 is hinged to one end of the two second connecting rods 512 and the first base 300 .

[0161] The second hinge shaft 514 is hinged to one end of the two second connecting rods 512 and the first base 300 .

[0162] Specifically, two second hinge shafts 514 are provided, which are respectively hinged to the two second connecting rods 512 and the first base 300. When connected, the second hinge shafts 514 are respectively inserted into the second connecting rods 512 and the first base 300 and hinged to the second connecting rods 512 through bearings, and hinged to the first base 300 through the bearing assembly.

[0163] The bearing assembly includes a bearing and a bearing seat. The bearing is connected to the second hinge shaft 514 , and the bearing seat is connected to the first base 300 to achieve hinge connection between the second hinge shaft 514 and the first base 300 .

[0164] The third hinge shaft 515 is hinged to the other ends of the two first connecting rods 511 and the cylinder frame;

[0165] The third hinge shaft 515 is arranged between the two first connecting rods 511 , with both ends thereof extending from the other ends of the two first connecting rods 511 . The third hinge shaft 515 is rotatably connected to the two first connecting rods 511 via bearings.

[0166] The cylinder frame is arranged between the two first connecting rods 511 and includes a first connecting plate, which is connected and fixed to the main cylinder rod;

[0167] and second connecting plates extending from both ends of the first connecting plate.

[0168] Both ends of the third hinge shaft 515 pass through the two second connecting plates respectively and are then inserted into the first connecting rod 511 .

[0169] The fourth hinge shaft 516 is hinged to the middle position of the two first connecting rods 511 and the other ends of the two second connecting rods 512 .

[0170] The fourth hinge shaft 516 is arranged in the middle of the two first connecting rods, and both ends thereof pass through the first connecting rod 511 and the second connecting rod 512 in sequence. The fourth hinge shaft 516 is connected to the first connecting rod 511 and the second connecting rod 512 via bearings.

[0171] During movement, the main cylinder rod of the main lifting cylinder 517 is actuated, exerting force on the fourth hinge shaft 516 connected thereto, causing the fourth hinge shaft 516 to perform horizontal telescopic movement. When the fourth hinge shaft 516 moves, it drives the first connecting rod 511 hinged thereto and the second connecting rod 512 hinged thereto to move, and finally drives the first hinge shaft 513 to move in the vertical direction.

[0172] Specifically, when the fourth hinge shaft 516 is extended by the main cylinder rod, the first hinge shaft 513 moves downward, and the entire lifting assembly is in the lowered position. At this time, the second base 400 connected to the first hinge shaft 513 is in the lowest position.

[0173] When the fourth hinge shaft 516 contracts under the drive of the main cylinder rod, the first hinge shaft 513 moves upward, and the entire lifting assembly is in the ascending position. At this time, the second base 400 connected to the first hinge shaft 513 is in the highest position.

[0174] The second base 400 can be quickly lifted and lowered by the main driving cylinder and the lifting connecting rod. The entire lifting structure is simple and the lifting action is fast, which can enable the second base 400 to drive the fork arm 100 clamp to quickly switch between the rising position and the lowering position.

[0175] The drive adopts the structure of the main lifting cylinder 517, which has a self-locking function and can be automatically locked when it rises to the rising position, so that the second base 400 and the fork arm 100 clamp above it remain in the rising position.

[0176] In some embodiments of the present application, the length of the second connecting rod 512 is 1 / 2 of the length of the first connecting rod 511. Setting the length of the second connecting rod 512 to half the length of the first connecting rod 511 can ensure that it does not interfere with the first connecting rod 511 when it moves.
