Description

Technical Field

[0001] This invention relates to the field of equipment for processing irregularly shaped parts, and in particular to a jig for processing truck parts. Background Technology

[0002] Some truck parts, due to their relatively complex structures, often require casting first, followed by machining to create features such as holes and cylindrical structures. For example... Figure 1 The truck components shown include a center plate and connecting blocks located on both sides of the center plate, with holes drilled in the connecting blocks. The parts to be processed are as follows: Figure 2 As shown, the device includes an intermediate plate 1, a first connecting block 2 located on the top surface 10 of the intermediate plate, and a second connecting block 2 located on the bottom surface 11 of the intermediate plate. The top surface 10 and the bottom surface 11 are opposite to each other. The intermediate plate 1, the first connecting block 2, and the second connecting block 3 are integrally formed, and connecting holes need to be machined on the first connecting block and the second connecting block. However, due to the relative complexity of this irregularly shaped part, how to achieve fast and accurate clamping and positioning to simplify the processing steps and increase processing efficiency is a problem that technicians are currently concerned about. Summary of the Invention

[0003] To address the technical problems existing in the background art, the present invention proposes a truck parts processing fixture.

[0004] The present invention proposes a truck parts processing fixture. The truck parts include an intermediate plate, a first connecting block located on the top surface of the intermediate plate, and a second connecting block located on the bottom surface of the intermediate plate, with the top and bottom surfaces facing each other. The fixture is used to process connecting holes on the first connecting block. Unlike the prior art, the fixture includes a base, on which a support block for supporting the intermediate plate is provided.

[0005] A first abutting block is slidably provided on the base, the bottom of the intermediate plate has a protrusion, the support block is located between the protrusion and the second connecting block, a first limiting groove is formed between the protrusion and the intermediate plate, and the first abutting block is slid to the first limiting groove or moved out of the first limiting groove.

[0006] A second abutment block is slidably provided on the base. The second abutment block and the first abutment block are arranged opposite to each other. Sliding the first abutment block or the second abutment block can adjust the distance between the first abutment block and the second abutment block. A second limiting groove is formed between the second connecting block and the intermediate plate. Sliding the second abutment block can move the second abutment block to or out of the second limiting groove.

[0007] During the processing, the bottom surface of the intermediate plate of the workpiece to be processed is first placed on the support block, and then the first and second clamping blocks are moved towards the intermediate plate. During this process, the first clamping block moves into the first limiting groove and the second clamping block moves into the second limiting groove, thereby achieving the clamping and positioning of the intermediate plate. This fixture combines the structural features of the irregular part itself, achieving more efficient clamping of the workpiece to be processed, and increasing the processing efficiency to a certain extent.

[0008] As a further optimization of the present invention, the first abutting block and the second abutting block move simultaneously toward the direction of the intermediate plate.

[0009] As a further optimization of the present invention, the lower surface of the first limiting groove is a first inclined surface that gradually slopes from the end near the first abutting block to the end away from the first abutting block and towards the middle plate, and the first abutting block has a pressing surface that matches the first inclined surface.

[0010] As a further optimization of the present invention, the first abutting block has a first upper support surface that supports the intermediate plate.

[0011] As a further optimization of the present invention, the support block has an auxiliary support portion for supporting the protrusion.

[0012] As a further optimization of the present invention, the second abutting block has a first extension on the side opposite to the second connecting block that abuts against the first side of the second connecting block, and the second abutting block has a second extension on the side opposite to the second connecting block that abuts against the second side of the second connecting block, the first side and the second side being opposite to each other and perpendicular to the bottom surface.

[0013] As a further optimization of the present invention, the first end extending away from the second abutment block is a first guide surface, and the second end extending away from the second abutment block is a second guide surface. The first guide surface and the second guide surface are inclined surfaces that gradually slope from the side away from the second abutment block toward the side closer to the second abutment block toward the direction closer to the second connecting block.

[0014] As a further optimization of the present invention, when the first clamping block and the second clamping block clamp the intermediate plate, the second connecting block abuts against the support block.

[0015] As a further optimization of the present invention, it also includes a first rotating abutment plate, one end of which is rotatably mounted on the base. Rotating the first rotating abutment plate causes it to abut against the first pressing block, thereby moving the first pressing block toward the middle plate.

[0016] As a further optimization of the present invention, a second rotating abutment plate is also included. One end of the second rotating abutment plate is rotatably mounted on the base. Rotating the second rotating abutment plate causes it to abut against the second pressing block, which in turn moves the second pressing block toward the middle plate.

[0017] The truck parts processing fixture proposed in this invention has a simple structure and combines the structural features of the irregular part itself, achieving more efficient clamping of the workpiece to be processed and increasing processing efficiency to a certain extent.

[0018] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figures 3-5 The truck parts processing fixture shown includes a middle plate 1, a first connecting block 2 located on the top surface 10 of the middle plate 1, and a second connecting block 3 located on the bottom surface 11 of the middle plate 1. The top surface 10 and the bottom surface 11 are opposite to each other. The fixture is used to process connecting holes on the first connecting block 2. Unlike the prior art, the fixture includes a base 4, on which a support block 9 is provided for supporting the middle plate 1.

[0027] A first abutting block 5 is slidably provided on the base 4. Specifically, a first mounting block 6 is detachably installed on the base 4. The first abutting block 5 is slidably installed on the first mounting block 6. The bottom of the intermediate plate 1 has a protrusion 12. The support block 9 is located between the protrusion 12 and the second connecting block 3. A first limiting groove 13 is formed between the protrusion 12 and the intermediate plate 1. The first abutting block is slid to the first limiting groove 13 or moved out of the first limiting groove 13.

[0028] A second abutment block 7 is slidably mounted on the base 4. Specifically, a second mounting block 8 is detachably mounted on the base 4. The second abutment block 7 is slidably mounted on the second mounting block 8. The second abutment block 7 and the first abutment block 5 are arranged opposite to each other. Sliding the first abutment block 5 or the second abutment block 7 can adjust the distance between the first abutment block 5 and the second abutment block 7. A second limiting groove 14 is formed between the second connecting block 3 and the intermediate plate 1. Sliding the second abutment block 7 can move the second abutment block 7 to or out of the second limiting groove 14.

[0029] During the processing, the bottom surface 11 of the intermediate plate 1 of the workpiece to be processed is first placed on the support block 9. Then, the first clamping block 5 and the second clamping block 7 are moved towards the intermediate plate 1 at the same time. During this process, the first clamping block 5 moves into the first limiting groove 13 and the second clamping block 7 moves into the second limiting groove 14, thereby realizing the clamping and positioning of the intermediate plate 1. This fixture combines the structural features of the irregular part itself, realizes more efficient clamping of the workpiece to be processed, and increases the processing efficiency to a certain extent.

[0030] Preferably, the second abutting block 7 has a first extension 70 on the side opposite to the second connecting block 3 that abuts against the first side of the second connecting block 3, and the second abutting block 7 has a second extension 71 on the side opposite to the second connecting block 3 that abuts against the second side of the second connecting block 3. The first side and the second side are opposite to each other and perpendicular to the bottom surface 11, further realizing the limiting and fixing of the parts to be processed.

[0031] Preferably, the end of the first extension 70 away from the second abutment block 7 is the first guide surface 700, and the end of the second extension 71 away from the second abutment block 7 is the second guide surface 710. The first guide surface 700 and the second guide surface 710 are inclined surfaces that gradually slope from the side away from the second abutment block 7 toward the side closer to the second abutment block 7 toward the second connecting block 3. During the process of the first abutment block 5 and the second abutment block 7 moving toward the intermediate plate 1, not only is the intermediate plate 1 clamped, but the position of the intermediate plate 1 is also adjusted, further increasing the processing accuracy.

[0032] Preferably, the second abutting block 7 has a second support surface 72 that supports the intermediate plate 1, further increasing the constraint on the intermediate plate 1.

[0033] Preferably, the lower surface of the first limiting groove 13 is a first inclined surface that gradually slopes from the end near the first abutting block 5 to the end away from the first abutting block 5 and towards the middle plate 1. The first abutting block 5 has a pressing surface that matches the first inclined surface. The matching of the first inclined surface and the first abutting block 5 enables the middle plate 1 to be positioned vertically, preventing the middle plate 1 from moving upward during the processing, and further increasing the processing accuracy.

[0034] Preferably, the first abutting block 5 has a first upper support surface 50 that supports the intermediate plate 1, further increasing the support and limiting of the intermediate plate 1.

[0035] Preferably, the support block 9 has an auxiliary support portion 90 for supporting the protrusion 12, which further increases the support limit for the intermediate plate 1.

[0036] Preferably, when the first clamping block 5 and the second clamping block 7 clamp the intermediate plate 1, the second connecting block 3 abuts against the support block 9.

[0037] Preferably, it also includes a first rotating abutment plate 15, one end of which is rotatably mounted on the base 4. Rotating the first rotating abutment plate 15 causes it to abut against the first pressing block 5, which in turn moves the first pressing block 5 toward the middle plate 1. Preferably, the first rotating abutment plate 15 has a first abutment portion, the outer side of which is an arc surface. Below the first abutment portion is a first mounting portion, which is rotatably connected to the base 4 via a rotating shaft 18. The first mounting portion and the first abutment portion are inclined surfaces that gradually slope away from the middle plate 1 from top to bottom to avoid motion interference.

[0038] Preferably, a first driving assembly for driving the first rotating contact plate 15 to rotate is also provided. The first driving assembly includes a lifting member 16, which can be a component such as an electric cylinder or a pneumatic cylinder in the prior art. In this embodiment, the lifting member 16 is a pneumatic cylinder. A fixing block 17 is fixed to the lifting end of the lifting member 16. A rotating shaft 18 is rotatably mounted on the fixing block 17. The axis of the rotating shaft 18 is parallel to the axis of rotation of the first rotating contact plate 15 relative to the base 4. The end of the first rotating contact plate 15 away from the first contact portion has an opening. The first rotating slide 150, the rotating shaft 18 is rotatably installed in the first rotating slide 150 and can slide in the first rotating slide 150. When the lifting component 16 drives the fixed block 17 to the highest position, the first rotating abutment plate 15 drives the first pressing block 5 to clamp the middle plate 1. When the lifting component 16 drives the fixed plate to the lowest position, the first rotating abutment plate 15 drives the first pressing block 5 to remove the pressing force on the middle plate 1. The middle plate 1 can be moved out from the first pressing block 5 and the second pressing block 7 by the robot arm.

[0039] In order to facilitate the return of the first clamping block 5 to its original position, an elastic element such as a spring can be provided between the first clamping block 5 and the base 4. When the first clamping block 5 clamps the intermediate plate 1, the spring is in a compressed state. When the clamping force on the first clamping block 5 is removed, the spring's restoring force drives the first clamping block 5 to slide out of the first limiting groove 13.

[0040] Specifically, the first abutting block 5 has a first abutting post, the first mounting block 6 has a sliding hole, a spring is installed in the sliding hole, and the first abutting post slides in the sliding hole and abuts against the spring.

[0041] Preferably, it also includes a second rotating abutment plate 19, one end of which is rotatably mounted on the base 4. Rotating the second rotating abutment plate 19 causes it to abut against the second pressing block 7, which in turn moves the second pressing block 7 toward the middle plate 1.

[0042] The structure of the second rotating contact plate 19 is the same as that of the first rotating contact plate 15, and will not be described in detail here. The base 4 is also provided with a second driving component that drives the second rotating contact plate 19 to rotate. The structure of the second driving component is the same as that of the first driving component, and will not be described in detail here.
