Description

Technical Field

[0001] The present application belongs to the technical field of sputtering target production, and more specifically relates to a target locking device for a sandblasting machine. Background Art

[0002] Sputtering targets are mainly used in the electronics and information industries, such as integrated circuits, information storage, liquid crystal displays, laser memory, electronic control devices, etc. Among them, the back tube of the target is a stainless steel tube. Before spraying the target, the back tube of the target must be sandblasted to give it a certain degree of roughness.

[0003] At present, sandblasting treatment in the market usually adopts sandblasting machine. The existing sandblasting machine is composed of sandblasting system, sand return system and control system. Steel sand is sprayed on the surface of the back tube through the sandblasting gun in the sandblasting system, and the surface of the back tube is impacted to a certain degree of roughness.

[0004] In the prior art, when sandblasting a target, the target is generally clamped and fixed by a locking device, which can cooperate with the target rotating motor while clamping, so as to achieve rotary sandblasting. However, the installation position of the existing target locking device is relatively limited and cannot adapt to targets of different lengths, so there is still room for improvement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a target material locking device for a sandblasting machine, which has the advantages of simple operation and adaptability to targets of different lengths.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a target locking device for a sandblasting machine, comprising a clamping base installed on the sandblasting machine and located on one side of the target material, the clamping base is provided with a tailstock ejection mechanism, the tailstock ejection mechanism, and a movable ejector pin is provided on the side of the tailstock ejection mechanism facing the target material, a movable limit plate is horizontally provided above the clamping base, the movable limit plate is connected to the clamping base by connecting rods on all sides, a movable block is horizontally provided between the clamping base and the movable limit plate, a trapezoidal screw is provided for rotation at the center of the movable limit plate, the lower end of the trapezoidal screw is threadedly connected to the movable block, vertical guide rods are provided on both sides of the length direction of the movable block, the lower end of the vertical guide rod passes through the clamping base and is fixedly connected with a clamping block, the upper surface of the clamping block is abutted against the lower surface of the frame of the sandblasting machine, and a limiting piece for limiting the rotation of the trapezoidal screw is provided on the movable limit plate.

[0007] By adopting the above technical solution, before sandblasting the spraying, first fix the driving end of the target to the target rotating motor to keep the position of its reference side unchanged. Then, according to the target of different lengths, adjust the position of the clamping base. After moving the clamping base to a suitable position, rotate the trapezoidal screw rod to make the movable block and the clamping block move upward. After the upper surface of the clamping block abuts against the lower surface of the sandblasting machine frame, use the limiting member to keep the trapezoidal screw rod stationary, and the fixation of the clamping base can be achieved. At this time, just use the tailstock ejection mechanism to press the movable center against the driven end of the target, and the target can be clamped, and at the same time, the selection function of the target can be realized.

[0008] In a preferred embodiment: a driving column is connected to the upper end of the trapezoidal screw rod, and a hexagonal driving nut is sleeved outside the driving column.

[0009] By adopting the above technical solution, the setting of the hexagonal driving nut can facilitate the user to rotate the trapezoidal screw rod in cooperation with a wrench, and the operation is more convenient.

[0010] In a preferred embodiment: roller assemblies are arranged on both sides of the lower end of the clamping base, and horizontal guide rods matched with the roller assemblies are arranged on the frame of the sandblasting machine.

[0011] By adopting the above technical solution, the mutual cooperation of the roller assemblies and the horizontal guide rods can increase the smoothness of the clamping base when moving on the frame of the sandblasting machine.

[0012] In a preferred embodiment: the limiting member is a butterfly positioning screw rod, a butting hole is opened on one side of the outer wall of the movable limiting plate, and one end of the butterfly positioning screw rod is threadedly connected with the butting hole and can abut against the surface of the trapezoidal screw rod.

[0013] By adopting the above technical solution, passing the butterfly positioning screw rod through the butting hole can abut against the trapezoidal screw rod, making the trapezoidal screw rod stationary, and further ensuring the stability when the movable block stops moving.

[0014] In a preferred embodiment: a sand-proof cover covering the outside of the vertical guide rod is connected between the movable limiting plate and the clamping base. The sand-proof cover is in a U shape, and the opening on its surface allows the tailstock ejection mechanism to pass through.

[0015] By adopting the above technical solution, the sand-proof cover can block the powder and dust generated during the sandblasting process, effectively ensuring the normal up and down movement of the movable block.

[0016] In a preferred embodiment: the tailstock ejection mechanism includes an ejection mounting seat, a tailstock sleeve and an ejection handwheel, the tailstock sleeve is located on the ejection mounting seat and is equipped with a screw and a screw nut inside, one end of the screw passes through the outside of the tailstock sleeve and is connected to the ejection handwheel, the inside of the tailstock sleeve is fixed with the screw nut, and the end of the tailstock sleeve extending toward the target material is provided with a shaft sleeve that is sleeved on the outside of one end of a movable ejector, and the shaft sleeve and the movable ejector are rotatably connected.

[0017] By adopting the above technical solution, when in use, rotating the ejection handwheel will drive the screw to rotate, and then the screw nut can drive the tailstock sleeve to move forward and backward. Since the sleeve on the tailstock sleeve is connected to the movable top, the movable top can be pressed against the target material.

[0018] Compared with the prior art, this application has the following beneficial effects:

[0019] 1. Simple operation and can adapt to targets of different lengths;

[0020] 2. The cooperation between the roller assembly and the horizontal guide rod can increase the smoothness of the movement of the clamping base on the frame of the sandblasting machine;

[0021] 3. The sandproof cover can block the powder and dust generated during the sandblasting process, which can effectively ensure the normal up and down movement of the movable block, thereby improving the stability during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] A target locking device for a sandblasting machine, as Figure 1-4 shown, includes a clamping base 1 installed on the sandblasting machine and located on one side of the target. A tailstock ejection mechanism 2 is provided on the clamping base 1. On the side of the tailstock ejection mechanism 2 facing the target, a movable ejector pin 3 is provided. The movable ejector pin 3 can cooperate with the tail target flange to tightly press against the target. A movable limit plate 4 is horizontally arranged above the clamping base 1. The periphery of the movable limit plate 4 is connected to the clamping base 1 through a connecting rod. A movable block 5 is horizontally arranged between the clamping base 1 and the movable limit plate 4. A trapezoidal screw rod 6 is rotatably arranged at the center of the movable limit plate 4. The lower end of the trapezoidal screw rod 6 is threadedly connected to the movable block 5. Vertical guide rods 51 are arranged on both sides in the length direction of the movable block 5. The lower ends of the vertical guide rods 51 penetrate through the clamping base 1 and are fixedly connected to a clamping block 511. The upper surface of the clamping block 511 abuts against the lower surface of the frame of the sandblasting machine. A limiting member 7 for restricting the rotation of the trapezoidal screw rod 6 is provided on the movable limit plate 4.

[0029] In one specific embodiment, as Figure 3-4 shown, roller assemblies 8 are installed on both sides of the lower end of the clamping base 1. A horizontal guide rod matched with the roller assemblies 8 is fixed on the frame of the sandblasting machine. Through the mutual cooperation of the roller assemblies 8 and the horizontal guide rod, the smoothness of the movement of the clamping base 1 on the frame of the sandblasting machine can be increased.

[0030] In one specific embodiment, as Figure 3-4 shown, the limiting member 7 is a butterfly positioning screw. An abutting hole is opened on one side of the outer wall of the movable limit plate 4. One end of the butterfly positioning screw is threadedly connected to the abutting hole and can abut against the surface of the trapezoidal screw rod 6.

[0031] It is worth mentioning that, as Figure 3-4 shown, in this embodiment, a sand-proof cover 9 covering the outside of the vertical guide rod 51 is connected between the movable limit plate 4 and the clamping base 1. The sand-proof cover 9 is integrally in a C shape, and its surface opening allows the tailstock ejection mechanism 2 to pass through. After passing the butterfly positioning screw through the abutting hole, it can abut against the trapezoidal screw rod 6, making the trapezoidal screw rod 6 keep still, thereby ensuring the reliability of the clamping block 511 pressing tightly against the frame.

[0032] In one specific embodiment, as Figure 4 shown, the upper end of the trapezoidal screw rod 6 is connected to a driving column 61. A hexagonal driving nut 611 is sleeved on the outside of the driving column 61, which can facilitate the user to rotate the trapezoidal screw rod 6 with a wrench, and the operation is more convenient.

[0033] In one specific embodiment, as Figure 3-4As shown, the tailstock ejection mechanism 2 includes an ejection mounting seat 21, a tailstock sleeve 22 and an ejection handwheel 23. The tailstock sleeve 22 is located on the ejection mounting seat 21 and is equipped with a screw and a screw nut inside. One end of the screw passes through the outside of the tailstock sleeve 22 and is connected to the ejection handwheel 23. The inside of the tailstock sleeve 22 is fixed with the screw nut. The end of the tailstock sleeve 22 extending toward the target material is provided with an outer sleeve sleeved on one end of the movable ejector pin 3, and the sleeve and the movable ejector pin 3 are rotatably connected.

[0034] The working process and beneficial effects of the utility model are as follows: before sandblasting, the driving end of the target material is first fixed to the target material rotating motor 10 so that its reference side position remains unchanged, and then the position of the sliding clamping base 1 is adjusted according to the target materials of different lengths. After the clamping base 1 is moved to a suitable position, the trapezoidal screw 6 is rotated to move the movable block 5 and the clamping block 511 upward. After the upper surface of the clamping block 511 is abutted against the lower surface of the frame of the sandblasting machine, the trapezoidal screw 6 is kept stationary by the butterfly positioning screw, so that the clamping base 1 can be fixed. At this time, it is only necessary to press the movable top against the driven end of the target material through the tailstock ejection mechanism 2 to clamp the target material, and at the same time realize the target material selection function.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
