Description

Technical Field

[0002] WC-Co carbide impact pins are core components of dispensing robots, characterized by low surface roughness, small size, and high requirements for positional and shape tolerances. To improve the wear resistance and service life of the impact pins, they are typically subjected to surface modification by irradiation with a high-current pulsed electron beam device before use.

[0003] In the prior art, due to the simple structure of the firing pin clamp, a single firing pin clamp can only hold a single firing pin for irradiation treatment. During irradiation treatment, the firing pin is first clamped and moved to the irradiation position, and then fixed for irradiation. After the firing pin is irradiated, another firing pin is replaced and the above steps are repeated. Although this type of clamp can complete the clamping, moving and fixing of the firing pin, the processing efficiency is low and the process is complicated because only a single firing pin can be irradiated at a time.

[0016] According to the technical solution provided in the embodiments of this application, there is a first space between the clamping top plate and the clamping bottom plate, and the positioning mechanism is provided on the connecting part within the first space.

[0032] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] As mentioned in the background section, to address the problems in the prior art, this application proposes a clamping device for a firing pin. This device clamps the firing pin 3 and mounts it integrally on a worktable, which irradiates the firing pin 3 with a high-current pulsed electron beam at an irradiation position. Please refer to... Figure 1 As shown, the device includes:

[0035] The clamping mechanism 2 has a clamping part. The firing pin 3 includes at least a clamping part and a treatment part to be irradiated. The clamping part is used to clamp the clamping parts of several firing pins 3, and the treatment part is exposed outside the clamping mechanism 2 on the side near the irradiation device. Specifically, the firing pin 3 can be a WC-Co cemented carbide firing pin 3, the treatment part is the part of the tip of the WC-Co cemented carbide firing pin that needs to be irradiated, and the clamping part is the part of the clamping mechanism 2 that contacts the firing pin 3.

[0036] Positioning mechanism 1 is mounted on the workbench and connected to clamping mechanism 2. Positioning mechanism 1 drives clamping mechanism 2 to move in a first plane so that the part to be treated of the impact pin 3 reaches the height of the irradiation position. The first plane is perpendicular to the extension direction of the impact pin 3.

[0037] The impact pins 3 possess strong cobalt magnetism and coercive magnetism, which can affect the trajectory of the high-current pulsed electron beam. The simultaneous presence of multiple impact pins 3 reduces the stability and uniformity of the irradiation treatment of the target area. This is why, in existing technologies, the impact pin 3 clamp only holds one impact pin 3 at a time for irradiation treatment. In this solution, the clamping mechanism 2 is designed with a placement spacing for the clamped impact pins 3. This placement spacing was obtained through multiple experiments. Based on the influence of the impact pin 3's own magnetism on the trajectory of the high-current pulsed electron beam, and considering both the acceptable degree of influence and the maximum processing capacity per batch, the spacing and arrangement of the impact pins 3 were determined. This can be understood as follows: when the impact pins 3 are arranged according to the placement spacing, the impact on the trajectory of the high-current pulsed electron beam is relatively small, maintaining good irradiation treatment stability and uniformity. For details, please refer to... Figure 6 As shown, the placement spacing is such that the center distance between any two adjacent firing pins 3 is 6.5 mm. Moreover, in order to clamp as many firing pins 3 as possible within the limited area of ​​the clamping mechanism 2, the overall shape of the area where the firing pins 3 are placed is designed with the center distance between any two firing pins 3 being fixed. After all the firing pins 3 are clamped, the outer contour area (i.e., the overall area) formed is shaped like a regular hexagon.

[0038] Therefore, this application reduces the influence of the magnetic field generated by the impactor pins 3 on adjacent impactor pins 3 by designing the arrangement and spacing of the impactor pins 3, thereby reducing the influence of the magnetism of the impactor pins 3 on the trajectory of the electron beam during irradiation. Through this design, the clamping mechanism 2 can be used to clamp multiple impactor pins 3 to be treated for irradiation. The first plane is the plane on which the clamping mechanism 2 is located. Firstly, the positioning mechanism 1 can be manually driven to move within the first plane, thereby moving the clamping mechanism 2 to bring the impactor pins 3 on the clamping mechanism 2 to the height of the irradiation position. Once this height is reached, the power output is stopped, and the clamping device is fixed to the worktable. The worktable rotates to send the entire clamping device holding the impactor pins 3 into the irradiation position, irradiating all the parts of the impactor pins 3 to be treated.

[0039] Using this clamping device, the clamping, moving, and fixing of the firing pins 3 can be completed in batches. Therefore, the firing pins 3 can be irradiated in batches with the help of this device, which can improve processing efficiency and simplify the processing process. At the same time, the irradiation of a large number of firing pins 3 in a single batch can also reduce production costs.

[0040] In a preferred embodiment, the clamping mechanism 2 includes at least two parallel clamping top plates 21 and clamping bottom plates 22. The clamping portion of the firing pin 3 passes through and is clamped in the clamping top plate 21. The end of the clamping portion away from the part to be processed abuts against the clamping bottom plate 22. The part to be processed is exposed on the side of the clamping top plate 21 away from the clamping bottom plate 22.

[0041] In a preferred embodiment, the clamping portion includes at least a clamping end near the processing portion, the clamping end being away from the processing side, and the outer diameter of the firing pin 3 gradually increases; the clamping portion includes:

[0042] The first clamping area 211 is provided on the clamping top plate 21. The first clamping area 211 has a plurality of clamping through holes 2111. The inner diameter of the clamping through holes 2111 is equal to the outer diameter of the clamping end of the firing pin 3.

[0043] The second clamping area is provided on the clamping base plate 22 in a region corresponding to the first clamping area 211, and the end of the part to be clamped that is away from the clamping end rests in the second clamping area.

[0044] For details, please refer to Figure 2 As shown, the clamping top plate 21 and the clamping bottom plate 22 have the same shape. The first clamping area 211 and the second clamping area are both raised frustum regions in the middle of the plate. The clamping top plate 21 has multiple clamping through holes 2111 in the first clamping area 211 according to the designed placement spacing. The clamping through holes 2111 are circular, and the center distance between any two adjacent clamping through holes 2111 is 6.5 mm. The inner diameter (diameter) of the clamping through holes 2111 is 3 mm. The second clamping area also has a raised frustum region, which is exactly the same as that of the first clamping area 211. Since the effective spot diameter of the electron beam emitted by the high-current pulsed electron beam device is 60 mm, the diameter of the frustum region of the clamping top plate 21 and the clamping bottom plate 22 is also set to 60 mm. This setting can ensure that all the impact pins 3 in the area are within the effective spot of the electron beam, and the irradiation of the electron beam can cover all the impact pins 3 in the area, realizing batch irradiation processing.

[0045] In a preferred embodiment, the clamping top plate 21 and the clamping bottom plate 22 are quadrilaterals, and each of the four corners of the clamping top plate 21 and the clamping bottom plate 22 is provided with a protrusion 23; the positioning mechanism 1 includes a connecting component 24, the connecting component 24 includes a detachably connected connecting part 241 and a locking part 242, the connecting part 241 passes through the protrusions 23 of the clamping top plate 21 and the clamping bottom plate 22, when the part to be treated of the firing pin 3 reaches the irradiation position, the locking part 242 cooperates with the connecting part 241 to clamp the clamping top plate 21 and the clamping bottom plate 22.

[0046] Please refer to Figure 2 and Figure 3As shown, the clamping top plate 21 and the clamping bottom plate 22 are shaped like an I-beam, with a rectangular protrusion 23 at each corner. Each protrusion 23 has a circular mounting hole. The connecting component 24 can be a matching machine screw and nut. The machine screw is the connecting part 241, and the nut is the locking part 242. The machine screw passes through the circular mounting holes of the clamping top plate 21 and the clamping bottom plate 22, and the large head of the machine screw is locked on the side of the clamping top plate 21 near the irradiation device. After the position is set (the impact pin 3 reaches the irradiation position, which is the position on the worktable where the irradiation device irradiates the impact pin 3), the nut is gradually locked from the side of the clamping bottom plate 22 away from the clamping top plate 21, so that the clamping top plate 21 and the clamping bottom plate 22 press and fix the impact pin 3.

[0047] In a preferred embodiment, the second clamping area is provided with a plurality of limiting portions, which are used to restrict the end of the part to be clamped that is away from the clamping end from sliding within the second clamping area.

[0048] After the clamping top plate 21 and the clamping bottom plate 22 press and fix the firing pin 3, since the bottom end of the firing pin 3 is against the second clamping area of ​​the clamping top plate 21, there may be a situation where the bottom slides and shifts. This will make it impossible to ensure that the firing pins 3, which should be placed parallel to each other, are parallel. This will have an adverse effect on the previously designed placement spacing and placement shape, and thus hinder our original intention of ensuring irradiation stability and uniformity. Therefore, this embodiment proposes to provide a number of limiting parts in the second clamping area. Each limiting part is correspondingly set with the clamping through hole 2111. Each set of corresponding limiting parts and clamping through hole 2111 cooperates to clamp one firing pin 3, and the extension direction of the firing pin 3 is kept perpendicular to the first plane.

[0049] In a preferred embodiment, the end of the part to be clamped away from the clamping end has a first boss; the limiting part includes a limiting groove 2211 corresponding to the clamping through hole 2111, and the shape and size of the limiting groove 2211 are adapted to the first boss.

[0050] For details, please refer to Figure 4As shown, this embodiment proposes an implementation method for the limiting part. The limiting part can optionally be provided with a limiting groove 2211, which can be a circular countersunk hole. In the frustum region of the second clamping area, a plurality of circular countersunk holes are provided. Each circular countersunk hole is coaxially arranged with the clamping through hole 2111. The bottom wall of the circular countersunk hole is flush with the bottom surface of the clamping base plate 22. Since the end of the part to be clamped of the impact pin 3 away from the part to be processed has a circular first protrusion, the inner diameter of the circular countersunk hole is slightly larger than the first protrusion, so that the first protrusion falls exactly into the circular countersunk hole and has no room to move. When the first protrusion is embedded in the limiting groove 2211, the clamping through hole 2111 is stuck at the clamping end and can no longer move downward. At this time, after the locking part 242 is locked, the impact pin 3 can be fixed.

[0051] To further improve the installation stability of the firing pin 3, the clamping through hole 2111 can also be provided with a certain extension. The extension is located on the side of the clamping top plate 21 away from the clamping bottom plate 22, and extends from the edge of the clamping through hole 2111 away from the clamping bottom plate 22. The extension can cover the part between the part to be processed and the part to be clamped of the firing pin 3, further improving the positional stability of the firing pin 3.

[0052] In a preferred embodiment, a first space is provided between the clamping top plate 21 and the clamping bottom plate 22, and the positioning mechanism 1 is provided on the connecting portion 241 within the first space.

[0053] Please refer to Figure 5 As shown, specifically, the positioning mechanism 1 is located between the clamping top plate 21 and the clamping bottom plate 22, which can effectively avoid the impact on the irradiation treatment when the positioning mechanism 1 is exposed to the outside.

[0054] In a preferred embodiment, the positioning mechanism 1 further includes:

[0055] Two first positioning rods 11, one end of which is hinged to two connecting parts 241 on the same side;

[0056] Two second positioning rods 12 are provided, with one end of each second positioning rod 12 hinged to the two connecting parts 241 on the other side. The ends of the second positioning rods 12 and the first positioning rods 11 away from the connecting parts 241 overlap, and a positioning post 14 is provided through the overlap. The positioning post 14 can move along the first positioning rod 11 and the second positioning rods 12.

[0057] Please refer to Figure 1As shown in the figure, the first positioning rod 11 and the second positioning rod 12 on the left side of the clamping mechanism 2 are connected to each other at the ends away from the connecting part 241, and the first positioning rod 11 and the second positioning rod 12 on the right side are connected to each other at the ends away from the connecting part 241, forming a triangular shape with the clamping mechanism 2, so that the entire clamping device is fixed and secure. The two sides of the clamping mechanism 2 are symmetrical. One end of the first positioning rod 11 and the second positioning rod 12 has a circular connecting through hole, which passes through the connecting part 241 of the connecting assembly 24. The other ends of the first positioning rod 11 and the second positioning rod 12 overlap and are connected by the positioning post 14. When the first positioning rod 11 and the second positioning rod 12 rotate along the hinge axis of the connecting part 241, the positioning post 14 can slide along the first positioning rod 11 / the second positioning rod 12.

[0058] In a preferred embodiment, both the first positioning rod 11 and the second positioning rod 12 have guide openings 13 along their extension direction, and the positioning post 14 passes through the overlapping part of the guide openings 13 of the first positioning rod 11 and the second positioning rod 12; the worktable has two fixing holes for fixing the clamping device, and the positioning post 14 is inserted into the fixing holes.

[0059] Specifically, the lengths of the first positioning rod 11 and the second positioning rod 12 are such that the distance between the circular mounting holes on the two adjacent protrusions 23 of the clamping base plate 22 and the clamping top plate 21 satisfies the side length condition of a triangle. The thickness of the part where the guide opening 13 is located is half the thickness of the part where the circular connecting through hole is located, to ensure that the first positioning rod 11 and the second positioning rod 12 can be stacked. The opening widths of the guide openings 13 of the two rods are equal, ensuring that when the first positioning rod 11 and the second positioning rod 12 are stacked and inserted into the positioning post 14 through the guide opening 13, they can fit tightly together. First, the positioning pin 14 is inserted into the fixing hole but not fixed. Then, the first positioning rod 11 and the second positioning rod 12 are rotated, and the positioning pin 14 slides within the guide opening 13 of the first positioning rod 11 and the second positioning rod 12, driving the clamping mechanism 2 to find the irradiation position. After the firing pin 3 reaches the position, it locks the positioning pin 14 in the fixing hole. At this time, the first positioning rod 11 and the second positioning rod 12 are also fixed, and the clamping mechanism 2 achieves positioning. The positioning pin 14 can be a mechanical screw, which can be locked by a matching nut.

[0060] Specifically, the connection between the first positioning rod 11 and the second positioning rod 12 is moved manually. Please refer to [reference needed]. Figure 1 and Figure 5 As shown, the movement path of the entire positioning mechanism 1 can be understood as follows: when pushed inwards synchronously, the clamping mechanism 2 moves upwards; when pulled outwards synchronously, the clamping mechanism 2 moves downwards. The positioning mechanism 1 can be fixed on workbenches of different sizes by rotating in cooperation between the rods. The first positioning rod 11 and the second positioning rod 12 can be fixed at different heights by rotating around the connecting part 241 of the connecting assembly 24, thus meeting the usage needs in more scenarios.

[0061] In a preferred embodiment, when the part to be processed of the firing pin 3 reaches the irradiation position, the locking part 242 cooperates with the connecting part 241 to clamp and fix the first positioning rod 11 and / or the second positioning rod 12 by the clamping top plate 21 and the clamping bottom plate 22.

[0062] Specifically, when the part to be processed of the firing pin 3 reaches the irradiation position, the locking part 242 locks, the clamping top plate 21 and the clamping bottom plate 22 clamp the first positioning rod 11 and / or the second positioning rod 12, thereby fixing the positioning mechanism 1 and finally fixing the firing pin 3 to complete the irradiation treatment.

[0063] Example 2

[0064] Based on Example 1, this embodiment proposes a method for using the clamping device, the specific steps of which are as follows:

[0065] The first step is to clean and dry the clamping base plate 22 and the clamping top plate 21 of the present invention with 99.9% anhydrous ethanol solution;

[0066] The second step is to insert the part to be processed of the firing pin 3 into the clamping through hole 2111 near the clamping base plate 22, and then extend it out of the clamping through hole 2111 away from the clamping base plate 22, exposing it outside the clamping mechanism 2.

[0067] Third, align the circular connecting through holes of the two first positioning rods 11 with the circular mounting holes of the protrusions 23 of the two upper clamping top plates 21, align the circular connecting through holes of the two second positioning rods 12 with the circular mounting holes of the two lower protrusions 23, and insert the connecting part 241 (machine screw) from the circular mounting hole on the side of the clamping top plate 21 away from the clamping bottom plate 22 and pass through the circular mounting hole and the circular connecting through hole to complete the hinge connection between the first positioning rod 11 / second positioning rod 12 and the clamping top plate 21.

[0068] Fourth step: Align the circular mounting hole of the protrusion 23 of the clamping base plate 22 with the connecting part 241 (machine screw), with the side of the clamping base plate 22 having the second clamping area facing the clamping top plate 21, insert the first boss of the firing pin 3 into the limiting groove 2211 of the clamping base plate 22, add the locking part 242 (matching nut) to the connecting part 241 (machine screw), complete the assembly of the clamping mechanism 2 and the firing pin 3, and realize the hinge connection between the first positioning rod 11 / second positioning rod 12 and the clamping mechanism 2 as a whole.

[0069] Fifth step, overlap the guide openings 13 of the first positioning rod 11 / second positioning rod 12 on the fixing hole of the worktable, and move the impact pin 3 to the height of the irradiation position by rotating the first positioning rod 11 / second positioning rod 12. Insert the positioning pin 14 (mechanical screw) into the fixing hole, and fix the entire clamping device connected in the fourth step on the worktable with the matching nut.

[0070] The sixth step involves using the clamping device, which was connected to the worktable in the fifth step and held a batch of firing pins 3, to send the firing pins 3 to the irradiation position by rotating the worktable.

[0071] Step 7: After being irradiated with a high-current pulsed electron beam, the positioning post 14 is pulled out from the fixing hole and the clamping device is removed from the worktable.

[0072] Step 8: Release the locking part 242 of the connecting assembly 24, remove the first positioning rod 11 / second positioning rod 12, separate the clamping top plate 21 from the clamping bottom plate 22, and remove the processed impact pin 3.

[0073] Step nine, and then repeating from step two onwards, can achieve batch and stable processing of the impactor 3 using a high-current pulsed electron beam device.
