Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a base welding fixture. Background Technology

[0002] Welding technology can be traced back to ancient times, such as the sword-making process and forging process in the Iron Age in China. As welding technology has gradually developed, early welding methods such as arc welding and gas welding have emerged. With the development of science and technology, welding technology has been continuously improved, and modern welding methods such as TIG, MIG, and laser welding have emerged. It has gradually achieved automation and intelligence, improving production efficiency and product quality. Welding fixtures are welding jigs manufactured using the dimensional coordinates of the parts to be welded, which are marked in the design of the product. They are commonly used in the electronics industry, especially in PCB welding.

[0003] Welding fixtures can clamp and fix the materials to be welded during the welding process to assist welding operations, but they still have certain problems: when welding materials with large mass, welding fixtures using cylinder power cannot provide stable clamping force. They are prone to damaging the materials due to excessive force, or failing to clamp stably due to insufficient force, thus failing to achieve high-precision clamping operations. Moreover, the cylinder stroke is limited and cannot perfectly adapt to clamping operations of materials of different sizes. Therefore, in view of the above situation, there is an urgent need to develop a base welding fixture to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this utility model is to provide a base welding fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a base welding fixture, comprising a base plate, a linear slide rail, a main drive assembly, and an auxiliary drive assembly. The linear slide rail is fixed at the top center of the base plate, and a locking assembly is installed on the linear slide rail. The main drive assembly is fixed at the top edge of the base plate, and the auxiliary drive assembly is fixed on the linear slide rail. A mounting plate is fixed on the auxiliary drive assembly. A motor is fixed on one side of the mounting plate, and a reducer connected to the motor is fixed on the opposite side of the motor. A thrust plate is fitted at the output end of the reducer. A positioning plate is fixed at the top edge of the base plate, and a positioning shaft passes through the positioning plate. A positioning baffle is fitted at one end of the positioning shaft, and an end cap is fitted at the other end of the positioning shaft. A detachable base to be welded is installed between the positioning baffle and the thrust plate.

[0006] The linear slide rail includes a guide rail a, a slider a, and a thrust slide plate. Multiple guide rails a are fixed on the base plate, the slider a is slidably mounted on the guide rail a, and the thrust slide plate is fixed on the slider a.

[0007] The auxiliary drive assembly includes a suspension and a lead screw cylinder. The suspension is fixed on the thrust plate, and the lead screw cylinder is fixed on the suspension.

[0008] The locking assembly includes a brake block, a lug, a connecting rod, a hinge seat, and a cylinder b. The lug is fixed on one side of the thrust slide plate. The brake block is rotatably mounted on the bottom edge of the lug. The cylinder b is vertically fixed on the side wall of the thrust slide plate. The bottom end of the piston rod of the cylinder b is fixed with a hinge seat. The brake block and the hinge seat are connected by a connecting rod drive.

[0009] Preferably, the main drive assembly includes a guide rail b, a slider b, and a cylinder a. The guide rail b is fixed on the base plate, the slider b is slidably mounted on the guide rail b, and the cylinder a is fixed on the slider b. A manual locking bolt is installed on one side of the slider b. Specifically, the position of the slider b can be fixed by the manual locking bolt, and the position of the cylinder a can be adjusted by the slider b in conjunction with the guide rail b. Thus, without changing the driving stroke of the cylinder a, it can drive the slider a, the thrust slide plate, and the auxiliary drive assembly to a longer stroke range.

[0010] Preferably, the piston rod end of cylinder a is fixedly connected to the edge of the thrust slide plate, and the cylinder a can drive the thrust slide plate and slider a to slide axially along the guide rail a.

[0011] Preferably, the mounting plate is vertically fixed on the slider of the lead screw electric cylinder. The lead screw electric cylinder can drive the mounting plate to make short-stroke displacement, which has higher control accuracy and torque, so that the thrust plate can provide sufficient clamping force to the base to be welded.

[0012] Preferably, a rubber brake pad with the same shape as the guide rail groove is installed on the side of the brake block near the guide rail a. When the brake block is in close contact with the guide rail a, the slider a is locked and cannot slide freely, thus avoiding the slider a being forced to move slightly due to the reverse force during the clamping of the base to be welded, thereby affecting the clamping stability.

[0013] Compared with the prior art, the present invention provides a base welding fixture, which has the following beneficial effects:

[0014] It uses cylinder a to drive the linear slide rail displacement, which can achieve a high response speed. Cylinder a is mounted on a manually lockable slider b. The installation position of cylinder a can be adjusted according to processing requirements, thereby controlling the end stroke range of the cylinder and adapting to the clamping operation of materials of more sizes.

[0015] It uses a lead screw electric cylinder to fix the mounting plate and motor. After the cylinder a drives the stroke to the specified range, the lead screw electric cylinder drives the motor and the thrust plate to move, which has high control precision and can apply greater clamping force.

[0025] Please see Figures 1-4 This utility model provides a technical solution: a base welding fixture, including a base plate 10, a linear slide rail 30, a main drive assembly 40, and an auxiliary drive assembly 50. The linear slide rail 30 is fixed at the top center of the base plate 10, and a locking assembly 80 is installed on the linear slide rail 30. The main drive assembly 40 is fixed at the top edge of the base plate 10. The auxiliary drive assembly 50 is fixed on the linear slide rail 30, and a mounting plate 60 is fixed on the auxiliary drive assembly 50. A mounting plate 60 is fixed on one side of the mounting plate 60. A motor 601 is provided, and a reducer 603 is fixedly provided on the opposite side of the motor 601 and driven thereto. A thrust plate 602 is sleeved on the output end of the reducer 603. A positioning plate 20 is fixedly provided at the top edge of the base plate 10. A positioning shaft 203 is passed through the positioning plate 20. A positioning baffle 201 is sleeved on one end of the positioning shaft 203. An end cover 202 is sleeved on the other end of the positioning shaft 203. A detachable base 70 to be welded is installed between the positioning baffle 201 and the thrust plate 602.

[0026] The linear slide rail 30 includes a guide rail a301, a slider a302 and a thrust slide plate 303. Multiple guide rails a301 are fixed on the base plate 10, the slider a302 is slidably mounted on the guide rail a301, and the thrust slide plate 303 is fixed on the slider a302.

[0027] The auxiliary drive assembly 50 includes a suspension 501 and a lead screw cylinder 502. The suspension 501 is fixed on the thrust slide plate 303, and the lead screw cylinder 502 is fixed on the suspension 501.

[0028] The locking assembly 80 includes a brake block 801, a lug 802, a connecting rod 803, a hinge seat 804, and a cylinder b805. The lug 802 is fixed on one side of the thrust slide plate 303. The brake block 801 is rotatably mounted on the bottom edge of the lug 802. The cylinder b805 is vertically fixed on the side wall of the thrust slide plate 303. The bottom end of the piston rod of the cylinder b805 is fixed with the hinge seat 804. The brake block 801 and the hinge seat 804 are connected by the connecting rod 803.

[0029] Preferably, the main drive assembly 40 includes a guide rail b401, a slider b402, and a cylinder a404. The guide rail b401 is fixed on the base plate 10, the slider b402 is slidably mounted on the guide rail b401, and the cylinder a404 is fixed on the slider b402. A manual locking bolt 403 is installed on one side of the slider b402. Specifically, the position of the slider b402 can be fixed by the manual locking bolt 403, and the slider b402, in conjunction with the guide rail b401, can adjust the position of the cylinder a404. Thus, without changing the driving stroke of the cylinder a404, it can drive the slider a302, the thrust slide plate 303, and the auxiliary drive assembly 50 to a longer stroke range.

[0030] Preferably, the piston rod end of cylinder a404 is fixedly connected to the edge of the thrust slide plate 303, and the cylinder a404 can drive the thrust slide plate 303 to slide axially along the guide rail a301 in conjunction with the slider a302.

[0031] Preferably, the mounting plate 60 is vertically fixed on the slider of the lead screw electric cylinder 502. The lead screw electric cylinder 502 can drive the mounting plate 60 to perform short-stroke displacement, which has higher control accuracy and torque, so that the thrust plate 602 can provide sufficient clamping force to the base 70 to be welded.

[0032] Preferably, a rubber brake pad with the same shape as the guide rail groove is installed on the side of the brake block 801 near the guide rail a301. When the brake block 801 is in close contact with the guide rail a301, the slider a302 is locked and cannot slide freely. This avoids the slider a302 being forced to move slightly due to the reverse force during the clamping process of the base to be welded 70, thus affecting the clamping stability.

[0033] Working principle: First, place the base 70 to be welded between the positioning baffle 201 and the thrust plate 602. Then, place one side of the base 70 to be welded onto one end of the positioning shaft 203. Next, start the cylinder a404 to drive the thrust slide plate 303 and the slider a302 to move a certain distance along the guide rail a301 toward the positioning baffle 201. At this time, the shaft at the thrust plate 602 is inserted into the through groove on the other side of the base 70 to be welded. The base 70 to be welded is in a state where both ends are lifted, but there is a certain gap between both ends. Then, start the screw cylinder 502 to drive the mounting plate 60 and the thrust plate 602 to move toward the positioning baffle 201 until the thrust plate 60... 2. The positioning baffle 201 clamps the two sides of the base 70 to be welded, and welding can then be performed. The motor 601 can be started, and the reducer 603 drives the clamped base 70 to rotate. It should be noted that when the size of the base 70 to be welded cannot accommodate the distance between the positioning baffle 201 and the thrust plate 602, the slider b402 can be manually pushed to move the cylinder a404. After the position is adjusted, the manual locking bolt 403 is tightened to fix the slider b402, thereby adjusting the position of the cylinder a404, thereby controlling the stroke range of its piston rod end, and finally adjusting the stroke range of the thrust plate 602.
