Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a zinc alloy processing clamp capable of preventing deformation. Background Art

[0002] Zinc alloy is an alloy made by mixing zinc with other metal or non-metal elements. It usually has excellent corrosion resistance, better plasticity and a low melting point, so it is widely used in mold manufacturing, automotive industry and other fields.

[0003] During the processing of zinc alloy parts, they are fixed by clamps to ensure the stability of the zinc alloy parts during processing and the quality of the products after processing. However, when processing thin zinc alloy parts, due to their own material and thickness, there is a problem of deformation during the clamping process, which makes it impossible to effectively protect, position and process the zinc alloy parts during the production process. Therefore, we propose a zinc alloy processing fixture that prevents deformation to solve the existing problem. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the background technology and to provide a zinc alloy processing fixture which can prevent deformation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a zinc alloy processing fixture for preventing deformation, comprising a mounting frame, a base, a processing table, a mounting frame, a support tube and a negative pressure pump, wherein the upper end of the mounting frame is provided with air holes distributed at equal intervals, the lower end of the mounting frame is connected and installed with a support tube, the lower end of the support tube is embedded and installed with a sealing ring, the suction end of the negative pressure pump is provided with a suction tube slidably inserted into the sealing ring, bases are provided on both sides of the mounting frame, a mounting frame is provided inside the upper end of the base, a rotating plate is provided at the upper end of the mounting frame, and rotating plates rotatably installed inside the mounting frame are provided at the front and rear ends of the rotating plate, one end of the rotating plate is provided with suction cups distributed at equal intervals, and one end of the suction cup is connected and installed with a hose that passes through the rotating plate and is connected with the two ends of the mounting frame.

The connecting plate moves synchronously with the telescopic end of the hydraulic rod, and when the connecting plate moves, it drives the toothed plate to move. Because the toothed plate meshes with the gear, the toothed plate pushes the gear.

[0007] Preferably, the upper end of the processing table is provided with a bracket for supporting the bottom of the hydraulic rod 1, and one end of the bracket is provided with a support ring. The bracket supports the lower end of the hydraulic rod 1.

[0008] Preferably, the outer wall of the support tube is sleeved with rotating rings located on the upper and lower sides of the support ring. The support tube is rotatably mounted within the support ring. A ring track is provided at the upper end of the rotating ring. Ball bearings distributed in an annular array and rotatably mounted within the ring track are rotatably mounted within the rotating ring. When the support tube rotates, the supporting ring limits the rotating ring, and the rotatably mounted balls within the rotating ring are simultaneously rotatably mounted within the ring track, thereby achieving rotational support for the support tube.

[0009] Preferably, a control valve is provided at the connection between the hose and the suction cup, a motor is provided at the front end of the mounting frame, and a rotating shaft rotatably mounted inside the mounting frame is provided at both the front and rear ends of the mounting frame, with the output end of the motor connected to the rotating shaft. The control valve controls the opening and closing of the hose and the suction cup.

[0010] Preferably, the upper end of the processing table is provided with two sets of symmetrically distributed guide rails, and the base is slidably mounted inside the guide rails. The base is slidably supported on the upper end of the processing table by the guide rails, and is slidably guided when the base moves laterally.

[0011] Preferably, the upper end of the processing table is provided with two symmetrically distributed hydraulic rods, the telescopic ends of the two hydraulic rods being connected to the base. When the hydraulic rods are in operation, the telescopic ends drive the base to move laterally, thereby adjusting the lateral position of the base.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. During use, the present invention places a sheet-like zinc alloy part on a mounting frame. The mounting frame is hollow inside, and an air hole communicating with the interior of the mounting frame is opened inside the upper end. When the negative pressure suction force is transmitted, the lower end of the zinc alloy part is adsorbed through the air hole, thereby achieving adsorption and positioning of the zinc alloy part, avoiding the situation where the zinc alloy part is easily deformed due to clamping the workpiece, improving the stability of the zinc alloy part during processing, and thus ensuring the quality of the subsequent zinc alloy part after punching, cutting and other processing.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 5 As shown, the present invention proposes a zinc alloy processing fixture for preventing deformation, comprising a mounting frame 1, a base 4, a processing table 6, a mounting frame 8, a support tube 15 and a negative pressure pump 19. The upper end of the mounting frame 8 is provided with equidistantly distributed air holes 9, the lower end of the mounting frame 8 is connected to the support tube 15 and installed, and the lower end of the support tube 15 is embedded with a sealing ring 21. The suction end of the negative pressure pump 19 is provided with a suction tube 20 that is slidably inserted into the sealing ring 21.

[0022] The outer wall of the support tube 15 is sleeved with a gear 11, one end of the gear 11 is provided with a tooth plate 17 meshing with the gear 11, one end of the tooth plate 17 is provided with a connecting plate 16, and one end of the tooth plate 17 is provided with a hydraulic rod 7 whose telescopic end is connected to the connecting plate 16;

[0023] The outer wall of the support tube 15 is sleeved with a rotating ring 23 located on the upper and lower sides of the support ring 22. The support tube 15 is rotatably installed inside the support ring 22. The upper end of the rotating ring 23 is provided with a ring track. The rotating ring 23 is rotatably installed with balls distributed in an annular array and rollingly installed inside the ring track.

[0024] Based on the implementation steps of Example 1: a thin sheet of zinc alloy parts is placed on the mounting frame 8, the zinc alloy parts cover the air holes 9, and the suction force of the negative pressure pump 19 is transmitted to the inside of the mounting frame 8 through the suction pipe 20 and the support pipe 15, and then acts on the lower end of the zinc alloy parts through the air holes 9 to adsorb and fix the zinc alloy parts. This avoids the situation where the zinc alloy parts are easily deformed by clamping them with the splint when they are fixed. The deformed zinc alloy parts cannot be effectively positioned and processed, resulting in material loss. The negative pressure adsorption ensures the stability of the zinc alloy parts, facilitating positioning and stabilization during subsequent processing.

[0025] During the processing, the hydraulic rod 7 drives the tooth plate 17 to move. Because the tooth plate 17 is engaged with the gear 11, it drives the support tube 15 to rotate, and then drives the zinc alloy parts adsorbed and fixed on the upper end of the mounting frame 8 to rotate. During the process of fixing the zinc alloy parts for processing, it is convenient to perform rotation adjustment, and the price flexibility is improved. The support tube 15 rotates on the outer wall of the suction tube 20 through the sealing ring 21, ensuring the stability of the suction tube 20 during use, and at the same time ensuring the effective rotation of the support tube 15.

[0026] like Figure 1-Figure 5 As shown, the zinc alloy processing fixture for preventing deformation proposed by the present invention is compared with the embodiment 1, and this embodiment further includes: a base 4 is provided on both sides of the mounting frame 8, a mounting frame 1 is provided inside the upper end of the base 4, a rotating plate 2 is provided on the upper end of the mounting frame 1, and a rotating plate 2 is provided at the front and rear ends of the rotating plate 2 and is rotatably mounted inside the mounting frame 1, and one end of the rotating plate 2 is provided with equidistantly distributed suction cups 12, and one end of the suction cup 12 is connected to a hose 14 that passes through the rotating plate 2 and is connected to the interior of the two ends of the mounting frame 8;

[0027] The upper end of the processing table 6 is provided with a bracket 18 for supporting the bottom of the hydraulic rod 7, and one end of the bracket 18 is provided with a support ring 22;

[0028] A control valve is provided at the connection between the hose 14 and the suction cup 12. A motor 3 is provided at the front end of the mounting frame 1. A rotating shaft 13 rotatably mounted inside the mounting frame 1 is provided at both the front and rear ends of the mounting frame 1. The output end of the motor 3 is connected to the rotating shaft 13.

[0029] Two sets of symmetrically distributed guide rails 5 are provided on the upper end of the processing table 6, and the base 4 is slidably installed inside the guide rails 5;

[0030] The upper end of the processing table 6 is provided with symmetrically distributed hydraulic rods 10, and the telescopic ends of the hydraulic rods 10 are connected to the base 4;

[0031] In this embodiment, during the processing of the zinc alloy part, the motor 3 drives the rotating shaft 13 to rotate. When the motor 3 is in operation, the rotating shaft 13 is driven to rotate, and the rotating shaft 13 drives the rotating plate 2 to rotate, thereby rotating the mounting frame 1, driving the mounting plate and the suction cup 12 to rotate. When the suction cup 12 is facing upward, it supports both sides of the lower end of the zinc alloy part. At the same time, the control valve controls the opening and closing of the hose 14, so that the suction force is transmitted to both sides of the lower end of the zinc alloy part, thereby achieving the fixation of the zinc alloy part, and adsorbing and fixing both sides of the lower end of the zinc alloy part, which is convenient for spraying the zinc alloy part. At the same time, the hydraulic rod 2 10 drives the base 4 to move horizontally, adjusts the relative position, and adapts to the adsorption and fixation of zinc alloy parts of different specifications;

[0032] At the same time, when the openings of the suction cups 12 are relatively distributed, the outer walls on both sides of the zinc alloy parts are adsorbed and fixed, and the negative pressure adsorption knot realizes multi-functional use and improves the flexibility of use.

[0033] The above specific embodiments are only several preferred embodiments of the present invention.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
