After the secondary clamping of the transmission block is completed, grinding is performed directly, which easily leads to an increase in the error of double-sided grinding of the transmission block and affects the machining accuracy of the transmission block. Therefore, improvement is needed. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, the utility model provides a technical solution: a grinding device for processing a transmission block, comprising a base 1, four groups of electric push rods 2 are fixedly installed at the central position of one side of the base 1, the top ends of the four groups of electric push rods 2 pass through the base 1 and are fixedly installed with a mounting plate 3, a grinding motor 4 is fixedly installed on the top of the mounting plate 3, and a grinding wheel 5 is provided at the output end of the grinding motor 4. By providing the electric push rods 2, the four groups of electric push rods 2 are controlled to be extended and retracted synchronously, thereby controlling the mounting plate 3 to move up and down on the top of the base 1, so as to facilitate the control of the distance between the grinding wheel 5 and the turning frame 22, and adjust the grinding amount of the transmission block by the grinding wheel 5.

[0023] A mounting frame 6 is fixedly installed on one side of the top of the base 1, and limiting slide bars 7 are symmetrically fixedly installed on both sides of the inner wall of the mounting frame 6, and a moving screw 8 is rotatably installed inside the mounting frame 6 between the two groups of limiting slide bars 7. The moving screw 8 and the two groups of limiting slide bars 7 are slidably connected with the moving seat 11. Because of the limiting slide bar 7, the moving screw 8 is controlled to rotate, so that the moving seat 11 slides on the surface of the moving screw 8 and the two groups of limiting slide bars 7, ensuring that the moving seat 11 will not tilt or deflect during the movement.

[0024] A rotating motor 9 is fixedly installed on one side of the mounting frame 6, and a bevel gear 10 is fixedly installed on one end of the moving screw 8 passing through the mounting frame 6 and the output end of the rotating motor 9, and the two sets of bevel gears 10 are meshed with each other. By providing a rotating motor 9, the rotating motor 9 is controlled to rotate forward and reverse, thereby controlling the moving screw 8 to rotate forward and reverse synchronously, so that the moving seat 11 can reciprocate on the surface of the moving screw 8.

[0025] A moving seat 11 is slidably installed inside the mounting frame 6, and mounting grooves 12 are respectively provided at both ends of both sides of the top of the moving seat 11. A limit plate 13 is slidably installed inside the mounting groove 12, and a clamping rod 14 is fixedly installed on one side of the limit plate 13, and two groups of clamping rods 14 penetrate the mounting groove 12 and extend to the outside of the moving seat 11 to be fixedly installed with a clamping plate 16, and a clamping spring 15 is provided on the surface of the clamping rod 14 located inside the mounting groove 12. Because the clamping spring 15 is provided, the limit plate 13 is pressed inside the mounting groove 12 under the rebound action of the clamping spring 15, so that the limit plate 13 can drive the clamping rod 14 to move, thereby pressing the clamping plate 16 on both sides of the moving seat 11;

[0026] Three groups of fixed blocks 17 are equidistantly fixedly installed on one side of the top of the clamping plate 16 close to the moving seat 11, and three groups of fixed sockets 27 are equidistantly provided on one side of the flip frame 22 away from the limiting protrusion 23, and the fixed sockets 27 correspond to the fixed blocks 17. By providing the fixed blocks 17 and the fixed sockets 27, when the clamping plate 16 is pressed tightly against both sides of the moving seat 11 and the flip frame 22, the fixed blocks 17 are inserted into the corresponding fixed sockets 27, thereby clamping and fixing the flip frame 22 on the top of the moving seat 11.

[0027] A fixing bolt 18 is provided at the central position of the surface of the clamping plate 16, and the fixing bolt 18 passes through the clamping plate 16 and is connected to the moving seat 11. Since the fixing bolt 18 is provided, the fixing bolt 18 is tightened to fix the clamping plate 16 to one side of the moving seat 11, ensuring that the fixing block 17 will not be separated from the fixing socket 27 at will;

[0028] Pads 19 are fixedly installed on both sides of the top of the moving seat 11, and fixed frames 20 are symmetrically fixedly installed on the top of the moving seat 11 at both ends of the pads 19. Because of the pads 19, when the flip frame 22 is fixed parallel to the top of the moving seat 11, one end of the flip frame 22 is padded on the top of the pads 19, so that the middle of the flip frame 22 is suspended on the top of the moving seat 11, so as to prevent the inclined transmission block from directly sticking to the top of the moving seat 11, resulting in the tilting of the grinding of the transmission block;

[0029] A limiting slide groove 21 is provided on one side of the fixed frame 20, and a flip frame 22 is provided between the two groups of fixed frames 20. A limiting protrusion 23 is fixedly installed at one end of both sides of the flip frame 22, and the limiting protrusion 23 corresponds to the limiting slide groove 21. By providing the limiting protrusion 23, when the flip frame 22 is controlled to slide between the two groups of fixed frames 20, the limiting protrusion 23 slides inside the corresponding limiting slide groove 21, thereby ensuring that the flip frame 22 will not arbitrarily separate from the moving seat 11 when it moves to the position at the top of the moving seat 11.

[0030] Adjusting screws 24 are symmetrically fixedly installed on both sides of the inside of the flip frame 22, and clamping plates 25 are slidably installed on the surfaces of the two groups of adjusting screws 24. An adjusting screw sleeve 26 is provided on the surface of the adjusting screw 24 on one side of the clamping plate 25. Because of the adjusting screw sleeve 26, after the transmission block is placed on the side of the clamping plate 25 away from the adjusting screw sleeve 26, the adjusting screw sleeve 26 is tightened to push the clamping plate 25 to move on the surface of the adjusting screw 24, thereby clamping the transmission block on one side of the clamping plate 25 and inside the flip frame 22.

[0031] The working principle of the utility model is:

[0032] After fixing the transmission block piece inside the flip frame 22 on one side of the clamping plate 25, control the flip frame 22 to be placed flat on the top of the moving seat 11, insert the fixed block 17 into the corresponding fixed socket 27, tighten the fixing bolt 18, and clamp and fix the flip frame 22 on the top of the moving seat 11, control the electric push rod 2 to telescopically adjust the distance between the grinding wheel 5 and the top of the base 1 to a suitable height, start the grinding motor 4 to control the grinding wheel 5 to rotate, and control the rotating motor 9 to rotate forward and reverse at the same time, so that the moving seat 11 drives the flip frame 22 and the transmission block to reciprocate at the bottom of the grinding wheel 5, thereby grinding the transmission block;

[0033] After one side of the transmission block is polished, the polishing motor 4 and the rotating motor 9 are stopped, the fixing bolts 18 are loosened to pull the clamping plate 16 away from the flip frame 22, and the flip frame 22 is controlled to flip and move between the two groups of fixed frames 20 so that the fixed sockets 27 correspond to the other group of clamping plates 16, the fixed block 17 is inserted into the corresponding fixed sockets 27, the fixing bolts 18 are tightened, and the polishing motor 4 and the rotating motor 9 are started and stopped, so as to polish the other side of the transmission block.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0035] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
