[0034] The embodiment provides a coating clamping device and a coating equipment, the coating equipment comprises a coating box and the coating clamping device, the coating clamping device is used for clamping a workpiece to be coated, the coating box is provided with a coating cavity, the coating cavity is provided with a furnace frame and a pushing piece, and the coating clamping device can be connected to the furnace frame. It should be noted that, except the coating clamping device, the rest of the structure of the coating equipment is prior art, which will not be described in detail here.

[0035] Specifically, as shown in Figure 1 and Figure 2 The coating clamping device comprises a rotating disc 1 and a clamping piece 2, the rotating disc 1 comprises a bottom plate 11 and a top plate 12 which are arranged at intervals and fixedly connected, the bottom plate 11 and the top plate 12 can rotate together, a stand column 13 is protruded on one side of the bottom plate 11 close to the top plate 12, the free end of the stand column 13 is a spherical surface 131, the clamping piece 2 is rotatably arranged on the rotating disc 1, a first end 201 of the clamping piece 2 penetrates the top plate 12 and abuts on the stand column 13, and the first end 201 and the spherical surface 131 are point contact, and a second end 202 of the clamping piece 2 is located on the upside of the top plate 12 and is used for carrying the workpiece to be coated.

[0036] When coating, the workpiece to be coated is fixed on the second end 202 of the clamping piece 2, and then the rotating disc 1 of the coating clamping device is connected to the furnace frame in the coating cavity. The furnace frame drives the rotating disc 1 to rotate, and the rotating disc 1 drives the clamping piece 2 and the workpiece to be coated thereon to revolve. In the process of revolving of the clamping piece 2 with the rotating disc 1, the pawl in the coating cavity drives the clamping piece 2 to rotate, so as to achieve the purpose of uniform coating of the workpiece. In the process of self-rotation of the clamping piece 2 relative to the rotating disc 1, the stand 13 is used to support the clamping piece 2. Since the first end 201 of the clamping piece 2 and the spherical surface 131 of the stand 13 are in point contact, the contact area is small, and therefore, compared with surface contact, the friction between the clamping piece 2 and the stand 13 is small, which can slow down the wear of the clamping piece 2 and prolong its service life, thereby prolonging the service life of the coating clamping device and enabling the coating clamping device to be applicable to loading of heavy workpieces.

[0037] Specifically, as shown in Figure 2 the first end 201 of the clamping piece 2 is provided with a matching hole 221, and the free end of the stand 13 is clearance-fitted in the matching hole 221, and the spherical surface 131 is in point contact with the hole bottom of the matching hole 221. Through the cooperation of the stand 13 and the matching hole 221, the stand 13 forms stable support for the clamping piece 2, and when the clamping piece 2 rotates relative to the stand 13, it rotates in point contact, the contact area is small, the friction is small, which can slow down the wear of the clamping piece 2 and prolong its service life.

[0038] In the embodiment, as shown in Figure 2 the matching hole 221 is a semispherical hole. The spherical surface 131 is specifically a semispherical surface. Along the axial direction of the clamping piece 2, the cross-sectional diameter of the semispherical hole is slightly larger than that of the spherical surface 131, so that the peripheral side of the spherical surface 131 is clearance-fitted with the matching hole 221, and the end of the spherical surface 131 is in point contact with the hole bottom of the matching hole 221. The semispherical hole and the spherical surface 131 are more adaptive, and the supporting effect is more stable. In other embodiments, the matching hole 221 can also be a cylindrical hole.

[0039] As shown in Figure 1 the number of clamping pieces 2 is set to be multiple, and the multiple clamping pieces 2 are uniformly and spacedly arranged along the circumferential direction of the rotating disc 1. One workpiece to be coated is clamped on each clamping piece 2. The bottom plate 11 is provided with multiple stands 13 corresponding to the clamping pieces 2 on the side close to the top plate 12. In the process of revolving of each clamping piece 2 with the rotating disc 1, the pawl in the coating cavity drives each clamping piece 2 in turn, so that each clamping piece 2 rotates respectively, thereby achieving the purpose of uniform coating of the workpiece. In this way, the coating of multiple workpieces can be realized at the same time, and the production efficiency is improved.

[0040] In the embodiment, as shown in Figure 1As shown, the number of clamping pieces 2 is set to six, and the six clamping pieces 2 are uniformly and spacedly arranged along the circumference of the turntable 1. Correspondingly, the bottom plate 11 is provided with six stand columns 13 on the side close to the top plate 12, which correspond to the clamping pieces 2. In other embodiments, the number of clamping pieces 2 and stand columns 13 can also be set to five, seven or other numbers, which can be flexibly set according to actual needs, and no specific limitation is made here.

Among them, the first end 201 of the clamping piece 2 refers to the end of the rod part 22 away from the clamping part 21, and the second end 202 of the clamping piece 2 refers to the end of the clamping part 21 away from the rod part 22.

[0042] Further, as shown in Figure 1 and Figure 2 , the second end 202 of the clamping piece 2 is provided with a threaded hole 211, which is used for detachable connection with the workpiece to be plated. Specifically, the workpiece to be plated is connected with the threaded hole 211 through an adapter with a screw rod, and different types of workpieces correspond to different adapters. When different types of workpieces need to be replaced, the adapter can be replaced by screwing it off, so that the plating clamping device can load workpieces of different types and specifications, and has strong versatility.

[0043] As shown in Figure 1 , a plurality of push grooves 212 are formed on the circumferential side wall of the clamping part 21 along the circumference thereof. The free end of the push piece abuts against the side wall of the push groove 212, and the clamping piece 2 is pushed to make the clamping piece 2 automatic.

[0044] Optionally, the turntable 1 and the clamping piece 2 are made of sus304 (304 stainless steel). 304 stainless steel is the most widely used chromium-nickel stainless steel, which has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, and can greatly ensure the service life of the turntable 1 and the clamping piece 2.

[0045] Optionally, the stand column 13 is made of T3 red copper material. The stand column 13 is a consumable part, and the T3 red copper material has good electrical conductivity and thermal conductivity, corrosion resistance and processing performance, so that the stand column 13 can be applied to more severe application environment.

[0046] Further, as shown in Figure 1 and Figure 2As shown, the film clamping device further comprises a bolt 3 and a sleeve 4, the bottom plate 11 and the top plate 12 are connected through the bolt 3, specifically, a first mounting hole 121 is formed on the top plate 12, a second mounting hole 111 is formed on the bottom plate 11 at a position corresponding to the first mounting hole 121, the bolt 3 is threaded through the first mounting hole 121 and is screwed with the second mounting hole 111, the head of the bolt 3 abuts against the upper surface of the top plate 12, and the sleeve 4 is sleeved outside the bolt 3 and is supported between the bottom plate 11 and the top plate 12. In this way, stable connection between the top plate 12 and the bottom plate 11 can be achieved, so that the top plate 12 and the bottom plate 11 form an integrated structure.

[0047] In the embodiment, as shown in the drawings, Figure 1 As shown, four bolts 3 are connected between the top plate 12 and the bottom plate 11, the four bolts 3 are uniformly and spacedly arranged along the circumference of the turntable 1 and are located inside the clamping piece 2, and one sleeve 4 is sleeved outside each bolt 3. In another optional embodiment, the number of the bolts 3 and the sleeves 4 can also be two, three, five or more, which can be flexibly set according to actual needs, and no specific limitation is made here.
