Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a clamping device for sandblasting the surface of small hardware parts. Background Technology

[0002] For small hardware products that require surface sandblasting, since these products are too small to be handled manually, it is necessary to design and develop corresponding sandblasting fixtures to clamp and fix them.

[0003] Among them, the Chinese utility model patent with patent number ZL202022836652.2 and patent name: a clamp for sandblasting small products, specifically discloses the following technical solution: a clamp for sandblasting small products, which includes a base plate, a spring and a clamp assembly. The base plate is provided with a placement hole for placing the workpiece to be sandblasted and a support opening located at one end of the placement hole. The clamp assembly passes through one end of the support opening and extends into the placement hole. A spring is sleeved on the clamp assembly. The workpiece is fixed in the placement hole by pushing the clamp assembly with the spring.

[0004] It should be noted that the aforementioned fixtures for sandblasting small products have the following defects, specifically:

[0005] Defect 1: The workpiece is clamped and fixed in the placement hole by the spring-push clamp assembly. Since the clamp assembly will contact the outer surface of the workpiece, the outer surface of the workpiece cannot be fully sandblasted. That is, it is not suitable for workpieces whose outer surface needs to be fully sandblasted. In addition, the clamping effect of the clamp assembly is prone to causing three types of damage (scratches, pressure marks, and impact marks) on the outer surface of the workpiece.

[0006] Defect 2: For workpieces requiring multi-face sandblasting, the sandblasting fixture for this small product cannot be quickly adjusted and switched, resulting in poor ease of use. Utility Model Content

[0007] The purpose of this utility model is to provide a small hardware surface sandblasting fixture device to address the shortcomings of the existing technology. This small hardware surface sandblasting fixture device has a novel structural design, convenient sandblasting surface adjustment and switching, and will not cause three-dimensional damage to the outer surface of the workpiece.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0009] A clamping device for sandblasting small hardware parts includes a base plate arranged horizontally, and the base plate is equipped with clamping and placing components.

[0010] The clamping and placement assembly includes a fixed panel located on the upper side of the base plate and arranged at an angle, and a vertically arranged support block is installed between the fixed panel and the base plate. The lower end of the support block is screwed to the base plate, and the upper end of the support block is screwed to the fixed panel.

[0011] The upper surface of the fixed panel is equipped with a placement panel, which has two symmetrically arranged positioning holes. The fixed panel is equipped with positioning posts corresponding to each positioning hole, and each positioning post is inserted into the corresponding fixed hole. The fixed panel is equipped with a first magnetic attractor, and the placement panel is equipped with a second magnetic attractor that is magnetically attracted to the first magnetic attractor.

[0012] The upper surface of the placement panel is provided with several buckles arranged in an array; when in use, the buckles are inserted into the inner cavity of the small hardware product.

[0013] The upper surface of the fixed panel has a first mounting hole corresponding to the first magnetic component, and the first magnetic component is embedded and fixed in the first mounting hole.

[0014] The lower surface of the placement panel has a second mounting hole corresponding to the second magnetic component, and the second magnetic component is embedded and fixed in the second mounting hole.

[0015] The placement panel is made of rigid plastic, and the buckle and the placement panel are an integral structure.

[0016] The upper end of the buckle is wedge-shaped, and a through groove is provided in the middle of the buckle.

[0017] The included angle between the fixed panel and the base plate is 45°.

[0018] The base plate is equipped with two symmetrically arranged clamping and placement components.

[0019] Compared with the prior art, the present invention has the following beneficial effects, specifically:

[0030] The present invention will now be described in conjunction with specific embodiments.

[0031] Example 1, as Figures 1 to 4 As shown, a clamping device for sandblasting the surface of small hardware parts includes a base plate 1 arranged horizontally, and a clamping and placing assembly 2 is mounted on the base plate 1.

[0032] Among them, such as Figures 1 to 4 As shown, the clamping and placement assembly 2 includes a fixed panel 3 located on the upper side of the base plate 1 and arranged at an angle. A vertically arranged support block 4 is installed between the fixed panel 3 and the base plate 1. The lower end of the support block 4 is screwed to the base plate 1, and the upper end of the support block 4 is screwed to the fixed panel 3. It should be noted that the included angle between the fixed panel 3 and the base plate 1 can be 45°.

[0033] Furthermore, such as Figures 1 to 4 As shown, the upper surface of the fixed panel 3 is provided with a placement panel 5. The placement panel 5 has two symmetrically arranged positioning holes 51. The fixed panel 3 is provided with positioning posts 6 corresponding to each positioning hole 51. Each positioning post 6 is inserted into the corresponding fixed hole. The fixed panel 3 is provided with a first magnetic attracting member 71. The placement panel 5 is provided with a second magnetic attracting member 72 that is magnetically attracted to the first magnetic attracting member 71.

[0034] Furthermore, such as Figures 1 to 4 As shown, the upper surface of the placement panel 5 is provided with a number of buckles 52 arranged in an array; when in use, the buckles 52 are inserted into the inner cavity of the small hardware product 8.

[0035] The following is a detailed description of the clamping device for sandblasting small hardware parts in Embodiment 1, with reference to the specific working process. The working process specifically includes the following steps:

[0036] Step a: Place several small hardware products 8 to be sandblasted on the placement panel 5. During this process, the small hardware products 8 to be sandblasted are clipped onto the buckle 52 of the placement panel 5, and the buckle 52 is inserted into the inner cavity of the small hardware products 8. That is, the small hardware products 8 to be sandblasted are clamped and placed through the buckle 52.

[0037] Step b: Place the placement panel 5, which contains several small hardware products 8 to be sandblasted, on the upper surface of the fixed panel 3. During this process, the positioning pin 6 of the fixed panel 3 is inserted into the positioning hole 51 of the placement panel 5. That is, the placement panel 5 is quickly aligned by the cooperation of the positioning pin 6 and the positioning hole 51. The placement panel 5 is magnetically fixed to the fixed panel 3 by the magnetic attraction between the first magnetic member 71 and the second magnetic member 72.

[0038] Step c: Place the small hardware part surface sandblasting fixture on the worktable of the automatic sandblasting equipment so that the surface of the small hardware part product 8 can be sandblasted by the sandblasting gun of the automatic sandblasting equipment.

[0039] Step d: After the small hardware product 8 has completed the first sandblasting surface or sandblasting angle sandblasting treatment, remove the placement panel 5 from the fixed panel 3, rotate the placement panel 5 180 degrees and put it back on the fixed surface so that the small hardware product 8 can perform the second sandblasting surface or sandblasting angle switching adjustment.

[0040] Step e: After the small hardware product 8 has completed the sandblasting operation, remove the sandblasting fixture for the small hardware product from the worktable of the automatic sandblasting equipment, and remove the placement panel 5 containing the sandblasted small hardware product 8 from the fixed panel 3.

[0041] It should be emphasized that the placement panel 5 in this embodiment is fixed to the fixed panel 3 by a magnetic structure composed of the first magnetic component 71 and the second magnetic component 72. This magnetic structure enables the placement panel 5 to be quickly assembled and disassembled, and is also conducive to switching and adjusting the sandblasting surface or sandblasting angle of the small hardware product 8.

[0042] It should be further emphasized that the placement panel 5 in this embodiment uses buckle 52 to clamp and place the small hardware product 8. The buckle 52 only contacts the inner surface of the small hardware product 8. That is, the clamping device for sandblasting the surface of small hardware products in this embodiment can effectively avoid the problem of three-dimensional damage to the outer surface of the workpiece.

[0043] In summary, the fixture device for sandblasting small hardware parts in this embodiment has the advantages of novel structural design and convenient adjustment and switching of sandblasting surface, and will not cause three-dimensional damage to the outer surface of the workpiece.

[0044] Example 2, as Figure 3 As shown, the difference between this embodiment 2 and embodiment 1 is that: the upper surface of the fixed panel 3 is provided with a first mounting hole 31 corresponding to the first magnetic suction member 71, and the first magnetic suction member 71 is embedded and fixed in the first mounting hole 31.

[0045] In addition, a second mounting hole 53 is provided on the lower surface of the placement panel 5 corresponding to the second magnetic member 72, and the second magnetic member 72 is embedded and fixed in the second mounting hole 53.

[0046] It should be explained that the first magnetic attractor 71 and the second magnetic attractor 72 in this embodiment can be magnetic components.

[0047] Example 3, as Figures 1 to 4 As shown, the difference between this embodiment three and embodiment one is that the placement panel 5 is a rigid plastic part, and the buckle 52 and the placement panel 5 are an integral structure.

[0048] Example 4, as Figure 1 As shown, the difference between this embodiment four and embodiment one is that the upper end of the buckle 52 is wedge-shaped, and the middle part of the buckle 52 is provided with a through groove 521.

[0049] When the small hardware product 8 is clipped onto the buckle 52, the wedge-shaped portion at the upper end of the buckle 52 facilitates the alignment of the inner cavity of the small hardware product 8. When clipping onto the small hardware product 8, the through groove 521 of the buckle 52 will adaptively shrink inward so that the buckle 52 can elastically press against the inner cavity wall of the small hardware product 8, thereby fixing the small hardware product 8.

[0050] Example 5, as Figures 1 to 4 As shown, the difference between this fifth embodiment and the first embodiment is that the base plate 1 is equipped with two symmetrically arranged clamping and placement components 2.

[0051] It should be noted that the small hardware parts surface sandblasting fixture device in this embodiment 5 uses two clamping and placing components 2 to clamp and place the small hardware parts product 8, so as to improve the sandblasting efficiency of the small hardware parts product 8.

[0052] The above description is only a preferred embodiment of this utility model.
