Technical Field

[0001] The utility model relates to the technical field of assembly jigs, and particularly relates to a centering vise assembly jig. Background Technique

[0002] The centering vise assembly jig is a tool for precisely clamping and positioning workpieces, and is widely used in the fields of machining, assembly, and maintenance. The centering vise assembly jig is an indispensable tool in machining and assembly. Through reasonable design and application, the clamping stability and machining accuracy of workpieces can be improved, the work efficiency can be enhanced, and it is crucial to select a suitable jig to ensure production quality and safety.

[0003] A spiral self-centering bench vise pressing device for machining, with the patent publication number CN114986212A, includes a bottom plate. A left jaw guide seat, a right jaw guide seat, and a central bearing mechanism are installed on the bottom plate. A left jaw and a right jaw are respectively slidably connected to the side walls of the left jaw guide seat and the right jaw guide seat. The left jaw and the right jaw are commonly threadedly connected to an adjusting screw rod. A handle is installed at the end of the adjusting screw rod. Orientation keys are installed on the side walls of the left jaw and the right jaw. The advantages are as follows: When the adjusting screw rod rotates one week, the left jaw and the right jaw can move towards or away from each other by two pitches simultaneously, achieving automatic centering and clamping, with accurate clamping and fast feeding speed. The workpiece is effectively clamped, and the maximum clamping force is determined by the strength of the pressure spring, which is controllable and adjustable.

Detailed implementation manner

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] During the process of repairing, processing or assembling parts, a centering vise assembly fixture needs to be used. The centering vise assembly fixture provided by the present invention is specifically used for centering clamping operations to save the physical strength of workers. During the clamping operation using this fixture, it is necessary to fix this fixture in the working position in advance to ensure that the fixture will not shift during the working process, thereby ensuring the normal operation of the fixture.

[0024] As Figures 1-6 shown, the present invention provides a technical solution: a centering vise assembly fixture, including a base 1. A chute 2 is opened on the outer wall of the base 1. A centering mechanism 3 is arranged in the middle of the chute 2. At both ends of the chute 2, there are slidingly inserted moving blocks 4 that are movable and installed on the centering mechanism 3. A mounting block 5 is installed on the top of the moving block 4. A detachable fixture mechanism 6 is installed on the mounting block 5. A fixing mechanism 10 for fixing and limiting the fixture mechanism 6 is installed on the mounting block 5. The centering mechanism 3 includes a round block 301 located in the middle of the chute 2. Both ends of the round block 301 are fixedly connected with round plates 302. Threaded rods 303 with opposite thread directions are respectively installed on the outer walls of the two round plates 302. A limiting mechanism 7 for reducing the rotational resistance of the round block 301 is installed in the middle of the inner wall of the chute 2.

[0025] It should be noted that when it is necessary to clamp the components, the staff rotates one of the threaded rods 303, drives the circular plate 302 and the circular block 301 to rotate, and then drives the other threaded rod 303 to rotate, so as to adjust the distance between the two moving blocks 4. Through the movement of the moving block 4 in the chute 2, the mounting block 5 and the fixture mechanism 6 on the mounting block 5 are driven to move, so as to center and clamp components of different sizes, making the workpiece centered, fixed and limited. By setting the fixture mechanism 6 to be detachable, it is convenient for users to replace different fixtures according to actual usage requirements. By setting the fixing mechanism 10, the fixture mechanism 6 can be fixed and limited, so that the fixture mechanism 6 will not shift during use, resulting in an error in the centering and clamping of the components. By setting the limiting mechanism 7, the resistance generated when the circular block 301 rotates can be reduced, thereby reducing the force consumed by the staff or the power when driven by a motor, which is beneficial to reducing energy consumption and the workload of the staff.

[0026] As Figures 2-4 shown, the limiting mechanism 7 includes a mounting seat 701 installed in the middle of the inner wall of the chute 2. A detachable mounting ring 703 is installed on the top of the mounting seat 701. Arc-shaped blocks 702 with hollow interiors are installed on the top inner wall of the mounting seat 701 and the bottom inner wall of the mounting ring 703. Strip-shaped grooves are opened at both ends of the inner wall of the arc-shaped block 702. Ring-shaped strip blocks 706 are inserted into the strip-shaped grooves. An arc-shaped plate 704 is fixedly connected between the two ring-shaped strip blocks 706. The inner wall of the arc-shaped plate 704 fits against the outer wall of the circular block 301. A number of circular seats 707 are installed on the outer wall of the arc-shaped plate 704. Rotatable balls 708 are installed on the circular seats 707. The balls 708 fit against the inner wall of the arc-shaped block 702.

[0027] It should be noted that when it is necessary to use the limiting mechanism 7, by fitting the arc-shaped plate 704 against the circular block 301, when the circular block 301 rotates, the arc-shaped plate 704 can be driven to rotate. Through the cooperation of the multiple circular seats 707 on the arc-shaped plate 704 and the balls 708, the function of a bearing can be achieved to reduce the friction generated when the circular block 301 rotates. At the same time, the mounting ring 703 is fixed to the mounting seat 701 by bolts, so that the two arc-shaped blocks 702 can be separated, which is convenient for the staff to disassemble and assemble the threaded rod 303 and is beneficial to the maintenance of the centering mechanism 3. At the same time, a notch can be opened on the circular block 301, and a groove block is fixedly connected to the arc-shaped plate 704. By inserting the groove block into the notch, the friction force can be increased, and further reduce the resistance generated when the circular block 301 rotates. Through the setting of the strip-shaped grooves and the ring-shaped strip blocks 706, the arc-shaped plate 704 can be limited.

[0028] As Figure 3 and Figure 4As shown, at both ends of the top outer wall of one arc-shaped plate 704, there are horizontally connected blocks 705 fixedly connected. At both ends of the bottom outer wall of the other arc-shaped plate 704, there are horizontal grooves 709 adapted to the horizontally connected blocks 705, and the horizontally connected blocks 705 are inserted into the horizontal grooves 709.

[0029] It should be noted that by setting the horizontally connected blocks 705 and the horizontal grooves 709, the two arc-shaped plates 704 can be closely attached together, which is beneficial to reducing the resistance generated when the round block 301 rotates.

[0030] As Figure 5 and Figure 6 As shown, the fixture mechanism 6 includes two T-shaped grooves 604 opened on one side outer wall of the mounting block 5. T-shaped blocks 603 are inserted into the T-shaped grooves 604. On the outer wall of one T-shaped block 603, there is a boss 601 located on the top of the mounting block 5. On the outer wall of the boss 601 facing the limiting mechanism 7, there are several vertical grooves opened. On the outer wall of the other T-shaped block 603, there is a rubber plate 602 located on the outer wall of the mounting block 5 facing the limiting mechanism 7.

[0031] It should be noted that when the fixture mechanism 6 needs to be used, through the boss 601 and the rubber plate 602 on the mounting block 5, the components can be fixed and limited. Through the several vertical grooves opened on the boss 601, the friction force when contacting the components can be increased. Through the set rubber plate 602, the function of buffering and clamping can be achieved. By providing two clamping methods through the boss 601 and the rubber plate 602, it is beneficial to clamp components with different hardnesses. Through the set T-shaped blocks 603 and T-shaped grooves 604, the boss 601 and the rubber plate 602 can be easily disassembled, which is beneficial for the staff to replace fixtures with different shapes according to the usage requirements and improve the adaptability.

[0032] As Figure 5 and Figure 6 As shown, the fixing mechanism 10 includes a limiting disk 1001 rotatably connected to one side outer wall of the mounting block 5. The inner wall of the limiting disk 1001 is attached to the outer walls of the two T-shaped blocks 603 on the mounting block 5. A pin 1002 is inserted into the outer wall of the limiting disk 1001. At the position corresponding to the pin 1002 on one side outer wall of the mounting block 5, there is a slot 1005 opened. The pin 1002 is inserted into the slot 1005. On one side outer wall of the pin 1002, there is a fixing plate 1004 fixedly connected. Between the other side outer wall of the fixing plate 1004 and one side outer wall of the mounting block 5, there is a spring 1003 surrounding the pin 1002 installed.

[0033] It should be noted that when the fixing mechanism 10 is required to be used, the two T-shaped blocks 603 can be limited and fixed through the limit disk 1001 so that they will not fall off from the T-shaped groove 604. When it is necessary to release the fixed limit of the T-shaped block 603, the staff pulls the fixing plate 1004 to stretch the spring 1003, so that the bolt 1002 is pulled out of the slot 1005, and then the limit disk 1001 is rotated until it does not contact the T-shaped block 603, and the limit fixation of the two T-shaped blocks 603 can be released.

[0034] As Figure 1 and Figure 5 shown, a plurality of mounting grooves 9 are formed in the outer wall of the top of the base 1. Hexagonal blocks 304 are mounted on the outer walls of the threaded rods 303. Hexagonal grooves are formed in the outer walls of the hexagonal blocks 304. Displacement sensors 11 are mounted on the mounting blocks 5. A scale 8 is mounted on one outer wall of the base 1.

[0035] It should be noted that through the provided mounting grooves 9, the base 1 can be fixed in the mounting position. Through the cooperation of the provided hexagonal blocks 304 and the hexagonal grooves, the threaded rod 303 can be rotated by the hexagonal insert block. Through the provided scale 8, the staff can directly observe the moving distance of the two moving blocks 4. Through the provided displacement sensors 11, the staff can accurately understand the moving distance of the two moving blocks 4.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended embodiments and their equivalents.
