Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of jigs, in particular to a left and right bracket jig. Background Art
[0002] A jig refers to a device used to fix a processing object during the mechanical manufacturing process, so that it occupies the correct position to receive construction or detection, also known as a fixture. Generally speaking, in any process of the technological process, a device used to quickly, conveniently and safely install a workpiece can be called a jig. A jig usually consists of a positioning element (to determine the correct position of the workpiece in the jig), a clamping device, a tool setting and guiding element (to determine the relative position between the tool and the workpiece or guide the tool direction), a indexing device (to enable the workpiece to complete the processing of several stations in one installation, including two types: rotary indexing device and linear moving indexing device), a connecting element, and a jig base, etc.
[0003] At present, an existing tooling jig is as Figure 1 shown, which includes a base. An installation block and a positioning plate are fixed on the upper end of the base. A convex block for placing a tooling socket is formed on the side wall of the installation block. A threaded rod is fixed on the side wall of the convex block. A pressing block is inserted on the threaded rod, and a nut is screwed on the threaded rod. When it is necessary to fix the tooling, the tooling is inserted on the convex block and the tooling is rotated so that the lower end of the tooling abuts against the positioning plate, so that the tooling is arranged parallel to the base. The pressing block is inserted on the threaded rod and the pressing block abuts against the side wall of the tooling. Then the nut is screwed on the threaded rod and the nut abuts against the side wall of the pressing block, so as to fix the tooling.
[0004] In the above solution, the prior art only fixes the tooling by squeezing the tooling with the pressing block, and the fixing effect is not good, resulting in easy deflection of the tooling during milling. At the same time, when the nut rotates and abuts against the side wall of the pressing block, it will drive the pressing block to rotate, thereby driving the tooling to rotate, resulting in the tooling not being arranged parallel to the base, thus affecting the milling quality of the tooling. Moreover, both the upper and lower ends of the tooling need to be milled, so the position of the tooling needs to be adjusted, and the adjusted tooling cannot abut against the positioning plate. The prior art usually sets two sets of tooling jigs with different heights of the positioning plates to fix two toolings at different positions respectively, thus increasing the production cost. Summary of the Utility Model
[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a left and right bracket jig. By providing a first fixing component and a second fixing component, the left and right brackets can be effectively fixed, solving the problem of poor fixing effect in the prior art. At the same time, by providing a positioning mechanism, two sets of tooling jigs do not need to be set, reducing the production cost.
[0006] The solution for the utility model to solve the technical problem is as follows:
[0007] A left - right bracket fixture, comprising a workbench and left - right brackets. A fixture base and a support block are installed at the upper end of the workbench. A positioning mechanism is provided at the upper end of the fixture base. The positioning mechanism includes a positioning block, a sliding component, and a clamping component. A first circular convex block is formed on the side wall of the support block, and a pressing component is provided on the side wall of the first circular convex block. A first fixing component is provided at the upper end of the fixture base, and a second fixing component is provided on the side wall of the support block. First through - holes and second through - holes are formed on the side walls of the left - right brackets.
[0008] When it is necessary to fix the left - right brackets at one position, after driving the positioning block to the required position through the sliding component, the positioning block is fixed through the clamping component, so that the first through - hole is arranged in cooperation with the first circular convex block, and the left - right brackets are abutted against the side wall of the support block. At the same time, the lower ends of the left - right brackets are abutted against the positioning block and the first fixing component, so that the left - right brackets are arranged parallel to the workbench, and it is ensured that the left - right brackets will not deflect. Then, the left - right brackets are pressed through the pressing component, so as to press - fix the left - right brackets, thereby ensuring that the milling quality of the left - right brackets is not affected. When it is necessary to fix the left - right brackets at another position, after driving the positioning block to move and fix it at the required position through the positioning mechanism, the first through - hole is arranged in cooperation with the first circular convex block, and the left - right brackets are abutted against the side wall of the support block. At the same time, the lower ends of the left - right brackets are abutted against the positioning block, and the second fixing component is clamped in the second through - hole, so that the left - right brackets are arranged parallel to the workbench, and it is ensured that the left - right brackets will not deflect. Then, the left - right brackets are pressed through the pressing component, so as to press - fix the left - right brackets, thereby ensuring that the milling quality of the left - right brackets is not affected, and two sets of tooling fixtures do not need to be set, thereby reducing the production cost.
[0009] By providing the first fixing component and the second fixing component, the left - right brackets can be effectively fixed, solving the problem of poor fixing effect in the prior art. At the same time, by providing the positioning mechanism, two sets of tooling fixtures do not need to be set, reducing the production cost.
[0010] The utility model is further set as: The sliding component includes a connecting plate fixed at the upper end of the fixture base. Two "T" - shaped blocks are symmetrically fixed on the side wall of the connecting plate. A sliding groove cooperating with the "T" - shaped block is formed on the side wall of the positioning block.
[0011] Through the above - mentioned technical solution, the positioning block is slidably connected to the connecting plate.
[0012] The utility model is further arranged as follows: The clamping component includes a clamping rod inserted on the side wall of the connecting plate. A first compression spring is sleeved on the side wall of the clamping rod. One end of the first compression spring is fixed on the side wall of the connecting plate, and the other end of the first compression spring is fixed on the side wall of the clamping rod. Two clamping holes are formed on the side wall of the positioning block, and a slot hole matching with the positioning block is formed at the upper end of the fixture base.
[0013] Through the above technical solution, when it is necessary to make the left and right brackets at one position parallel to the workbench, the clamping rod is pulled outwards so that the positioning block can move freely. After driving the positioning block to the required position, the clamping rod is released, and the clamping rod moves inwards under the action of the first compression spring and is inserted into one of the clamping holes, thereby fixing the positioning block. At the same time, the lower end of the positioning block is inserted into the slot hole, so as to ensure that the positioning block does not shake. Thus, when the left and right brackets at one position abut against the upper end of the positioning block, they are parallel to the workbench. When it is necessary to make the left and right brackets at another position parallel to the workbench, repeat the above operation to make the clamping rod inserted into another clamping hole, thereby fixing the positioning block. At the same time, the lower end of the positioning block is inserted into the slot hole, so as to ensure that the positioning block does not shake. Thus, when the left and right brackets at another position abut against the upper end of the positioning block, they are parallel to the workbench, so as to ensure that the milling quality of the left and right brackets is not affected.
[0014] The utility model is further arranged as follows: The pressing component includes a screw rod installed on the side wall of the first circular convex block. A circular pressing block is inserted on the screw rod. A second circular convex block matching with the first through hole is formed on the side wall of the circular pressing block, and a nut is screwed on the screw rod.
[0015] Through the above technical solution, when it is necessary to press and fix the left and right brackets, the circular pressing block is inserted on the screw rod, and the circular pressing block abuts against the side wall of the left and right brackets. At the same time, the second circular convex block is inserted into the first through hole, thereby improving the stability of the left and right brackets and preventing the left and right brackets from shaking. Then the nut is screwed on the screw rod, and the nut abuts against the side wall of the circular pressing block, thereby pressing and fixing the left and right brackets.
[0016] The utility model is further arranged as follows: The first fixing component includes a "C"-shaped plate fixed at the upper end of the fixture base.
[0017] Through the above technical solution, when the first through hole and the first circular convex block are arranged in cooperation, at the same time, the lower ends of the left and right brackets abut against the upper ends of the positioning block and the "C"-shaped plate, so that the left and right brackets can only move back and forth, ensuring that the left and right brackets will not deflect.

[0019] Through the above technical solution, when the left and right brackets at one position are inserted and sleeved on the first circular convex block, the clamping post is squeezed and contracted by the left and right brackets, so that the fixation of the left and right brackets will not be affected. When the left and right brackets at another position are inserted and sleeved on the first circular convex block, the clamping post is inserted and sleeved in the second through hole under the action of the second compression spring and abuts against the inner wall of the second through hole, so that the left and right brackets can only move back and forth, ensuring that the left and right brackets will not deflect.
