DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a workbench auxiliary bracket, including a workbench plate 1, three groups of T-shaped slide grooves 101 are equidistantly arranged on the top of the workbench plate 1, and the T-shaped slide grooves 101 correspond to T-shaped blocks 201. A concave seat 2 is arranged on the top of the workbench plate 1, three groups of T-shaped blocks 201 are equidistantly fixedly installed on the bottom of the concave seat 2, and fixed blocks 202 are symmetrically fixedly installed on both sides of the inner wall of the concave seat 2. Because the T-shaped slide grooves 101 and the T-shaped blocks 201 are arranged, the T-shaped blocks 201 at the bottom of the concave seat 2 are inserted into the corresponding T-shaped slide grooves 101 to ensure that the concave seat 2 will not slide, deviate or misalign when it is fixed on the top of the workbench plate 1.

[0021] Positioning slots 102 are symmetrically provided on both sides of the workbench 1, and the positioning slots 102 correspond to the positioning columns 304. Because the positioning slots 102 are provided, the positioning columns 304 are adjusted to be stuck in different positions of the positioning slots 102, thereby adjusting the positions of the concave seat 2 and the arc-shaped bracket 4 on the top of the workbench 1.

[0022] Fixed protrusions 203 are symmetrically fixedly installed on both sides of the top of the concave seat 2, and fixed clamping plates 204 are slidably installed on the surfaces of the two groups of fixed protrusions 203. A fixing nut 205 is provided on the top of the concave seat 2 between the two groups of fixed protrusions 203, and the top of the fixing nut 205 passes through the fixed clamping plate 204. By providing the fixed clamping plate 204, after the bottom plate 401 is clamped at the corresponding position of the top of the concave seat 2, the fixed clamping plate 204 is pushed to fit tightly against the two sides of the bottom of the bottom plate 401, and then the fixing nuts 205 are tightened to install and fix the fixed clamping plate 204, thereby ensuring that the bottom plate 401 is fixed to the top of the concave seat 2.

[0023] L-shaped mounting plates 3 are symmetrically fixedly installed on both sides of the concave seat 2, and a limiting slide groove 301 is provided at the bottom of one side of the L-shaped mounting plate 3. Two groups of moving rods 302 are symmetrically slidably installed on the top of the L-shaped mounting plate 3, and the top ends of the two groups of moving rods 302 pass through the L-shaped mounting plate 3 and are fixedly installed with a top plate 306. Because the top plate 306 is provided, the top plate 306 is pulled to drive the two groups of moving rods 302 to move synchronously, thereby controlling the connecting protrusion 303 to drive the positioning column 304 to move smoothly inside the limiting slide groove 301;

[0024] The two sets of moving rods 302 are located at one end of the bottom of the L-shaped mounting plate 3 and are fixedly installed with a connecting protrusion 303. A positioning column 304 is fixedly installed on one side of the connecting protrusion 303, and the positioning column 304 passes through the limiting slide groove 301. A fixing spring 305 is provided on the surface of the moving rod 302 located between the L-shaped mounting plate 3 and the connecting protrusion 303. An arc-shaped bracket 4 is provided on the top of the concave seat 2. By providing a fixing spring 305, the top plate 306 is loosened. Under the rebound action of the fixing spring 305, the connecting protrusion 303 is pressed down, so that the positioning column 304 moves down inside the limiting slide groove 301 and is stuck in different positions inside the positioning slot 102.

[0025] A bottom plate 401 is fixedly installed at the bottom of the arc-shaped bracket 4, and fixed slots 402 are symmetrically provided on both sides of the bottom plate 401, and the fixed slots 402 correspond to the fixed blocks 202. Because the fixed slots 402 and the fixed blocks 202 are provided, after the bottom plate 401 is inserted into the top of the concave seat 2, the fixed slots 402 are stuck on the surface of the corresponding fixed blocks 202, ensuring that the arc-shaped bracket 4 will not slide freely on the top of the concave seat 2.

[0026] The working principle of the utility model is:

[0027] Select a suitable arc bracket 4 according to the specifications of the processed parts, insert the bottom plate 401 into the top of the concave seat 2, push the two sets of fixed card plates 204 to fit tightly against the top of the bottom plate 401, tighten the fixing nuts 205 to install and fix the fixed card plates 204, connect and fix the arc bracket 4 to the concave seat 2, pull the two sets of top plates 306 upward to drive the connecting protrusions 303 to move upward, so that the positioning card column 304 slides up inside the limiting slide groove 301, and then insert the T-shaped card block 201 at the bottom of the concave seat 2 into the T-shaped slide groove 101. The positioning column 304 is inserted into the positioning slot 102, and the position of the concave seat 2 on the top of the worktable 1 is adjusted according to the length of the processed part. The positioning column 304 slides inside the positioning slot 102 until the concave seat 2 moves to a suitable position on the top of the worktable 1. At the same time, the positioning column 304 can be inserted into a suitable position inside the positioning slot 102. The top plate 306 is released. Under the elastic action of the fixing spring 305, the connecting protrusion 303 drives the positioning column 304 to move down and insert it into a suitable position inside the positioning slot 102.
