Description

Technical Field

[0001] This application relates to the field of tooling, and in particular to an auxiliary tooling for painting pins. Background Technology

[0002] In the field of mechanical manufacturing, pins are common connecting parts, and surface anti-corrosion treatment, such as painting, is a key process to ensure their service life.

[0003] Currently, the painting process mainly consists of manual and automatic spraying. Manual spraying involves workers holding spray guns and applying paint, while automatic spraying uses a robotic arm to control the movement of the air jet. To improve stability during spraying, auxiliary fixtures are typically used to clamp the pin. These fixtures mainly consist of a support frame and several clamping plates, each rotatably connected to the support frame, and each clamping plate has a torsion spring on its rotating shaft. The spring force of the torsion springs presses the clamping plates firmly against the pin, allowing the worker to apply paint to it.

[0004] In practical use, because different pins have different painting positions, after a portion of the pin is painted, it needs to be flipped over. Currently, flipping the pin requires workers to remove it and reposition it, which increases their workload and can easily damage some of the paint, thus affecting the final painting effect. Utility Model Content

[0005] To address the aforementioned issues, this application provides an auxiliary tooling for painting pins.

[0006] This application provides an auxiliary tooling for painting pins, which adopts the following technical solution:

[0007] An auxiliary tooling for spray painting pins includes a frame and a support frame. The support frame is rotatably connected to the frame. The support frame is provided with a plurality of support plates and a plurality of sets of storage holes. Each set of storage holes corresponds to a support plate. The storage hole set includes a first support hole and a second support hole. One side of the support plate corresponds to a first support hole and the other side corresponds to a second support hole. The support plate is provided with a clamping assembly that cooperates with the first support hole and the second support hole.

[0008] By adopting the above technical solution, workers place the pins to be painted into the respective first and second support holes, and then use a clamping assembly to limit the pins. At this point, workers can begin painting the pins. After painting a portion of the pin, workers can directly rotate the support frame to paint different parts of the pin, reducing the need to remove and reposition the pin, thus providing convenience for workers painting the pins.

[0009] Preferably, the clamping assembly includes a first quick positioning clamp and a second quick positioning clamp, which are arranged symmetrically on the support plate. The first quick positioning clamp is positioned opposite to a first support hole at a corresponding position, and the second quick positioning clamp is positioned opposite to a second support hole at a corresponding position.

[0010] By adopting the above technical solution, after the pin is placed in the first support hole and the second support hole, the worker uses the first quick-positioning fixture to limit the pin in the first support hole, and then uses the second quick-positioning fixture to limit the pin in the second support hole, thus completing the pin's positioning. At this time, under the action of the first and second quick-positioning fixtures, the worker can easily and quickly fix the pin.

[0011] Preferably, both the first and second quick positioning fixtures are provided with shims.

[0012] By adopting the above technical solution, the shim block can easily compensate for the distance between the first and second quick positioning fixtures and the corresponding pins, so that the first and second quick positioning fixtures can fix the pins more stably.

[0013] Preferably, the frame is provided with a control component, which includes a gearbox and a control panel. The gearbox is mounted on the frame, the output end of the gearbox is connected to the rotating shaft of the support frame, and the input end of the gearbox is connected to the control panel.

[0014] By adopting the above technical solution, when it is necessary to adjust the position of the pin, the worker rotates the control panel, which controls the rotation of the gear inside the gearbox. The output end of the gearbox then controls the rotation of the support frame, thereby realizing the function of adjusting the position of the pin.

[0015] Preferably, the frame has a through hole, the support frame has a limit hole, a locking rod is provided in the through hole, and the end of the locking rod away from the frame passes through the limit hole.

[0016] By adopting the above technical solution, after the position of the support bracket is adjusted, the worker passes the locking rod through the through hole and the limiting hole in sequence to limit the support bracket. At this time, under the limiting action of the locking rod, the pin is not easily separated from the support bracket during the painting process.

[0017] Preferably, the support frame is provided with a plurality of positioning components, each group of positioning components corresponding to a support plate. The positioning component includes a support, a first positioning seat and a second positioning seat. The support is disposed on the support frame. The first positioning seat and the second positioning seat are slidably connected to the support. The first positioning seat extends into a first support hole and the second positioning seat extends into a second support hole. The support is provided with an assisting component that provides assistance to the first positioning seat and the second positioning seat.

[0018] By adopting the above technical solution, when the pin needs to be initially positioned, the worker inserts the pin into the first or second support hole. At this time, under the action of the assisting component, the first positioning seat abuts against the pin located in the first support hole, and the second positioning seat abuts against the pin located in the second support hole, thereby initially positioning the pin. At this time, under the action of the positioning component and the assisting component, the pin is stably abutted against the first or second support hole.

[0019] Preferably, the assist component includes a connecting rod and a spring. A connecting groove is provided on the support. The connecting rod is slidably connected to the inner wall of the connecting groove. The side of the first positioning seat near the support and the side of the second positioning seat near the support are both connected to the connecting rod at the corresponding positions. The spring is disposed in the connecting groove, with one end connected to the connecting rod and the other end connected to the bottom of the connecting groove.

[0020] By adopting the above technical solution, when the pin needs to be placed, the worker pushes the first or second positioning seat, which in turn moves the connecting rod at the corresponding position, causing the spring to be compressed. The worker then places the pin in the first or second support hole, and under the action of the spring's rebound force, the first and second positioning seats can initially position the pin.

[0021] Preferably, a corrugated tube is fitted onto the connecting rod, with one end of the corrugated tube connected to the support and the other end connected to the first positioning seat or the second positioning seat at the corresponding position.

[0022] By adopting the above technical solution, the corrugated pipe makes the connecting rod less susceptible to the effects of paint spraying during the pin painting process, thus facilitating the subsequent movement of the connecting rod.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a support bracket that is rotatably connected to the frame, the position of the pin can be easily changed, reducing the number of steps for workers to reposition the pin and lowering the possibility of reduced painting effect during the repositioning process, thus providing convenience for the painting of the pin.

[0025] 2. By setting up shims, the distance between the first and second quick positioning fixtures and the corresponding pins is compensated, so that the first and second quick positioning fixtures can more stably limit the pins;

[0026] 3. By setting up positioning components and assist components, the pin is initially positioned, making it less likely for the pin to separate from the support during the painting process. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] Example 1:

[0033] Embodiment 1 of this application discloses an auxiliary tooling for painting pins. (Refer to...) Figure 1An auxiliary tooling for painting pins includes a frame 1 and a support frame 2, which is rotatably connected to the frame 1. The support frame 2 has several support plates 21 and several sets of storage holes 3 for storing pins, each corresponding to a support plate 21. Each storage hole set 3 consists of a first support hole 31 and a second support hole 32. One side of each support plate 21 corresponds to a first support hole 31, and the other side corresponds to a second support hole 32. Each support plate 21 is equipped with a clamping assembly 4. The clamping assembly 4 limits the position of the pins in the first and second support holes 31 and 32, allowing the worker to paint the pins. After painting a portion of the pin, the worker can rotate the support frame 2 to paint different positions of the pin, reducing the need for repositioning the pin and thus providing convenience for the worker's pin painting process.

[0034] Reference Figure 1 The clamping assembly 4 includes a first quick-positioning clamp 41 and a second quick-positioning clamp 42, which are arranged symmetrically on the support plate 21. The first quick-positioning clamp 41 is opposite to the first support hole 31, and the second quick-positioning clamp 42 is opposite to the second support hole 32.

[0035] In order to improve the stability of the pin during painting, both the first quick positioning fixture 41 and the second quick positioning fixture 42 are equipped with shims 43.

[0036] The worker places the pin in the first support hole 31 and the second support hole 32, and then places the shim 43 on the pin. The worker then uses the first quick positioning jig 41 and the second quick positioning jig 42 to limit the pin. At this time, under the action of the shim 43, the distance between the first quick positioning jig 41 and the second quick positioning jig 42 and the corresponding position of the pin is compensated, so that the first quick positioning jig 41 and the second quick positioning jig 42 can hold the pin more stably.

[0037] Reference Figure 1 To adjust the position of the support frame 2, a control component 5 is provided on the frame 1. The control component 5 includes a gearbox 51 and a control panel 52. The gearbox 51 is fixed on the frame 1, the output end of the gearbox 51 is connected to the support frame 2, and the input end of the gearbox 51 is connected to the control panel 52.

[0038] The frame 1 has a through hole 11 and the support frame 2 has a limit hole 22. A locking rod 111 is provided in the through hole 11, and the end of the locking rod 111 away from the frame 1 passes through the limit hole 22.

[0039] After painting a portion of the pin, the worker rotates the control panel 52. The control panel 52 activates the input end of the gearbox 51, which in turn drives the support bracket 2 to rotate, adjusting the position of the pin. At this point, the worker can paint different positions on the pin. When the through hole 11 is aligned with the limiting hole 22, the worker passes the locking rod 111 through the through hole 11 and the limiting hole 22 in sequence to limit the support bracket 2, making it less likely to move during the pin painting process, thus improving the stability of the pin painting.

[0040] Reference Figure 1 The frame 1 is equipped with casters 12 on the side away from the support frame 2, which facilitates the movement of the frame 1 by workers.

[0041] The implementation principle of Embodiment 1 of this application is as follows: The worker places the pin in the first support hole 31 and the second support hole 32, and then uses the clamping assembly 4 to limit the pin, allowing the worker to spray paint the pin. After painting a portion of the pin, the worker rotates the support frame 2 to adjust the position of the pin, at which point the worker can paint different positions of the pin. In this way, the support frame 2 reduces the step of repositioning the pin, lowers the possibility of reduced painting effect due to repositioning, and thus provides convenience for the worker to paint the pin.

[0042] Example 2:

[0043] Reference Figure 2 and Figure 3 The difference from Embodiment 1 of this application is that the support frame 2 is provided with several sets of positioning components 6, each positioning component 6 corresponding to a support plate 21. Each positioning component 6 includes a support 61, a first positioning seat 62, and a second positioning seat 63. The support 61 is fixed to the support frame 2, and both the first positioning seat 62 and the second positioning seat 63 are slidably connected to the support 61. The first positioning seat 62 extends into the first support hole 31, and the second positioning seat 63 extends into the second support hole 32. Furthermore, the support 61 is provided with an assist component 7 that provides assistance to the first positioning seat 62 and the second positioning seat 63.

[0044] The assist component 7 includes a connecting rod 71 and a spring 72. A connecting groove 611 is provided on the support 61, and the connecting rod 71 is slidably connected to the inner wall of the connecting groove 611. The spring 72 is disposed in the connecting groove 611, with one end connected to the connecting rod 71 and the other end connected to the bottom of the connecting groove 611. The side of the first positioning seat 62 near the support 61 and the side of the second positioning seat 63 near the support 61 are both connected to the connecting rod 71 at corresponding positions.

[0045] When the worker places the pin in the first support hole 31 and the second support hole 32, the worker pushes the first positioning seat 62 and the second positioning seat 63, causing the connecting rod 71 to move and the spring 72 to be in a compressed state. The worker then places the pin in the first support hole 31 and the second support hole 32. At this time, under the action of the spring 72's rebound force, the first positioning seat 62 initially positions the pin in the first support hole 31, and the second positioning seat 63 initially positions the pin in the second support hole 32.

[0046] Reference Figure 3 The first positioning seat 62 and the second positioning seat 63 are both provided with positioning arc surfaces 64, which abut against the pins at the corresponding positions, making it less likely for the first positioning seat 62 and the second positioning seat 63 to damage the pins.

[0047] Reference Figure 3 A bellows 8 is fitted onto the connecting rod 71. One end of the bellows 8 is connected to the support 61, and the other end is connected to the first positioning seat 62 or the second positioning seat 63 at the corresponding position. The bellows 8 prevents paint from adhering to the connecting rod 71 during the pin painting process, reducing the possibility of damage to the connecting rod 71.

[0048] The implementation principle of Embodiment 2 of this application is as follows: During the process of placing the pin, the worker first uses the positioning component 6 to initially position the pin to determine the position of the pin and the support bracket 2. The worker then uses the clamping component 4 to perform a second positioning of the pin, making it less likely for the pin to separate from the support bracket 2 during the painting process, thereby facilitating the worker's painting of the pin.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
