Description

Technical Field

[0001] This utility model relates to the field of positioning technology, and in particular to a positioning fixture for welding equipment. Background Technology

[0002] Welding is a process that uses heat, pressure, or both, with or without filler material, to bond two or more metal (or other thermoplastic, such as plastic) workpieces together. It is widely used in the fields of construction, automobile manufacturing, shipbuilding, energy, and aerospace.

[0003] With the rapid development of the manufacturing industry, welding technology plays a vital role in industrial production. Welding quality not only affects the performance and lifespan of products, but also directly relates to production efficiency and cost control. Existing positioning and clamping devices have relatively simple structures and cannot effectively position, clamp, and fix workpieces. When welding, workpieces are prone to move and cannot be properly clamped and fixed, affecting the welding effect. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning fixture for welding equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning fixture for welding equipment includes a welding table, a welding device is arranged above the welding table, and positioning clamping devices are fixedly installed on both sides of the welding table. The positioning clamping devices include a positioning plate, a clamping plate is arranged above the positioning plate, a support frame is fixedly installed on the side of the positioning plate above the clamping plate, a rotary motor is fixedly installed on the top of the support frame, a rotary shaft is vertically driven by the rotary motor, and a main gear is fixedly installed at the bottom of the rotary shaft.

[0007] Both sides of the positioning plate are fixedly installed with extension blocks, and each extension block has a threaded rod vertically installed inside. Each threaded rod has a secondary gear fixedly installed at its top, and both secondary gears mesh with the main gear.

[0008] Furthermore, in a preferred configuration, bearings are embedded within both of the two extension blocks, and threaded rods are vertically fixedly inserted into both bearings.

[0009] In addition, a preferred structure is that nut pairs are fixedly installed on both sides of the clamping plate, and the two nut pairs are respectively threaded onto the two threaded rods.

[0010] In addition, a preferred structure is that the positioning plate and the clamping plate are connected at their four corners by four telescopic columns.

[0011] In addition, a preferred structure is that a plurality of first anti-slip protrusions are fixedly installed on the top surface of the positioning plate.

[0012] In addition, a preferred structure is that a plurality of second anti-slip protrusions are fixedly installed on the bottom surface of the clamping plate.

[0013] Furthermore, in a preferred configuration, the first and second anti-slip bumps are made of a soft anti-slip material.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, the rotation of the main gear drives the synchronous and unidirectional rotation of the two auxiliary gears, which in turn causes the clamping plate to move downward, precisely positioning and clamping the workpiece. This ensures that the workpiece is firmly fixed during welding, preventing it from moving and facilitating the welding process. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 The system includes a welding table 1, a welding device 2 above the welding table 1, and positioning clamping devices 3 fixedly installed on both sides of the welding table 1. The positioning clamping devices 3 include a positioning plate 4, a clamping plate 5 above the positioning plate 4, a support frame 7 fixedly installed on the side of the positioning plate 4 above the clamping plate 5, a rotary motor 8 fixedly installed on the top of the support frame 7, a rotary shaft 12 vertically driven by the rotary motor 8, and a main gear 13 fixedly installed at the bottom of the rotary shaft 12.

[0025] Among them, the positioning plate 4 has an extension block 51 fixedly installed on both sides, and a threaded rod 9 is vertically installed in each of the two extension blocks 51. A secondary gear 14 is fixedly installed on the top of each of the two threaded rods 9, and the two secondary gears 14 mesh with the main gear 13.

[0026] Meanwhile, bearings 10 are embedded in both of the two extension blocks 51, and threaded rods 9 are vertically fixedly inserted into both bearings 10. When the threaded rods 9 rotate, they will not drive the extension blocks 51 to rotate synchronously.

[0027] Furthermore, nut pairs 11 are fixedly installed on both sides of the clamping plate 5. The two nut pairs 11 are threaded onto the two threaded rods 9 respectively. When the threaded rods 9 rotate, the clamping plate 5 moves downward to clamp the workpiece under the cooperation of the nut pairs 11 and the threaded rods 9.

[0028] Meanwhile, the positioning plate 4 and the clamping plate 5 are connected at their four corners by four telescopic columns 6, which facilitates the positioning, clamping and fixing of the workpiece.

[0029] The top surface of the positioning plate 4 is fixedly equipped with several first anti-slip protrusions 41, while the bottom surface of the clamping plate 5 is fixedly equipped with several second anti-slip protrusions 52.

[0030] Furthermore, the first anti-slip protrusion 41 and the second anti-slip protrusion 52 are made of soft anti-slip material. The first anti-slip protrusion 41 and the second anti-slip protrusion 52 ensure that the workpiece will not be damaged when it is clamped, while also playing an anti-slip role.

[0031] In this embodiment, the two workpieces to be welded are placed in the two positioning and clamping devices 3 respectively. Then, the rotary motor 8 is started to drive the rotary shaft 12 to rotate, which drives the main gear 13 to rotate synchronously. Since the two auxiliary gears 14 mesh with the main gear 13, when the main gear 13 rotates, it drives the two auxiliary gears 14 to rotate synchronously in the same direction, which in turn drives the two threaded rods 9 to rotate synchronously in the same direction. The two nut pairs 11 drive the clamping plate 5 to descend under the rotation of the threaded rods 9, and the telescopic column 6 will shorten to ensure that the workpiece is clamped. When the workpiece is clamped, the rotary motor 8 stops working, and the workpiece is precisely positioned and clamped between the positioning plate 4 and the clamping plate 5. Then, the welding equipment 2 is started to weld the two workpieces.

[0032] In this invention, the rotation of the main gear 13 drives the synchronous and unidirectional rotation of the two auxiliary gears 14, thereby causing the clamping plate 5 to move downward, accurately positioning and clamping the workpiece, so that the workpiece is firmly fixed during welding and will not move, which facilitates the welding process.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
