Description

Technical Field

[0001] The utility model relates to the technical field of blade clamps, in particular to a diamond blade sharpening clamp. Background Art

[0002] Diamond blades are made of diamond particles and metal. Diamond blades need to be sharpened during the processing.

[0003] When sharpening diamond blades, the blades need to be positioned by a fixture before stable grinding can be performed. There are two common clamping methods. One is to use screws to tighten the eccentric positioning, and the other is to use a pneumatic elbow clamp for positioning.

[0004] The eccentric positioning method by screw compression is inefficient, and like the positioning method of the pneumatic toggle clamp, it is impossible to simultaneously position the blade in the longitudinal and transverse directions, making it difficult to ensure that the blade fits in the tool pocket, reducing the stability of the blade clamping. For this reason, we propose a diamond blade sharpening fixture. Utility Model Content

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a diamond blade grinding fixture as Figures 1-4 shown, which includes a base 101 and a positioning mechanism. A tool pocket 102 is opened at the top end of the base 101. A blade 103 is inserted into the tool pocket 102. The blade 103 is stuck inside the tool pocket 102, and then is positioned by the positioning mechanism so as to stably perform grinding processing on the blade 103 subsequently;

[0025] In a preferred embodiment, the positioning mechanism is arranged above the blade 103. The positioning mechanism includes a pressure head 201. An insertion mechanism is arranged between the pressure head 201 and the blade 103. A connecting rod 202 is fixedly connected to the top end of the pressure head 201. A downward pressing mechanism is arranged above the connecting rod 202. A support block 203 is arranged above the base 101. A limiting hole 204 is opened at the top end of the support block 203. The outer wall of the connecting rod 202 is movably inserted into the inner wall of the limiting hole 204. A transverse pulling mechanism is arranged on one side of the support block 203. Through the cooperation of the downward pressing mechanism, the pressure head 201 drives the insertion mechanism to work to perform longitudinal limitation on the blade 103. Then, through the cooperation of the transverse pulling mechanism, the support block 203 drives the connecting rod 202 to move, so that the pressure head 201 and the insertion mechanism also apply a transverse acting force to the blade 103, thereby stably clamping the blade 103 inside the tool pocket 102 and improving the clamping stability of the blade 103.

[0026] Among them, the plug-in mechanism includes an insert block 401, which is fixedly connected to the bottom end of the pressure head 201, and a socket 402 is opened at the top of the blade 103. The shape of the insert block 401 matches the shape of the socket 402, and the insert block 401 is inserted into the inner wall of the socket 402. The pressure head 201 moves downward to drive the insert block 401 to be inserted into the socket 402 until the pressure head 201 rests against the top of the blade 103. At this time, the socket 402 will also limit the insert block 401 laterally, so that when the pressure head 201 moves laterally, it can also drive the blade 103 to move laterally.

[0027] Among them, the pressing mechanism includes a first cylinder 301 installed on the top of the support block 203, and the output end transmission of the first cylinder 301 is provided with a connecting plate 302. The bottom end of the connecting plate 302 is fixedly connected to the top of the connecting rod 202. The first cylinder 301 can drive the connecting plate 302 to rise and fall when it is working, thereby driving the pressure head 201 to rise and fall under the connection of the connecting rod 202, thereby improving the convenience and stability of the operation of the pressure head 201.

[0028] The horizontal pulling mechanism includes a slot 501 provided at the top of the support block 203, the inner wall of the slot 501 is slidably connected with a horizontal pulling block 502, a second cylinder 503 is installed at the top of the base 101, and a connecting mechanism is provided between the second cylinder 503 and the horizontal pulling block 502. The horizontal pulling block 502 can be driven to move by the operation of the second cylinder 503, and the horizontal pulling block 502 moves against the inner wall of the slot 501, so as to drive the support block 203 to move. The limiting hole 204 and the limiting position of the connecting rod 202 can make the horizontal pulling block 502 move. The movement of the support block 203 can drive the connection rod 202 to move, thereby moving the pressure head 201. Under the mutual limitation of the plug block 401 and the socket 402, the pressure head 201 can move horizontally and can also drive the blade 103 to move horizontally. The first cylinder 301 and the second cylinder 503 are electrically connected to the external power supply through an external switch, respectively, to facilitate the operator to control the first cylinder 301 and the second cylinder 503, thereby improving the safety and convenience of the operation of the first cylinder 301 and the second cylinder 503.

[0029] Among them, the back side of the base 101 is fixedly connected with a fixed plate 601, the front side of the fixed plate 601 is fixedly connected with a fixed block 602, the front side of the support block 203 is provided with a connecting groove 603, the fixed block 602 is inserted into the inside of the connecting groove 603, and an extrusion mechanism is provided between the fixed plate 601 and the horizontal pull block 502. The bottom end of the support block 203 is fixedly connected with a slider 802, and the top end of the base 101 is provided with a slide groove 801. The outer wall of the slider 802 is slidably connected with the inner wall of the slide groove 801. Through the mutual limitation of the fixed block 602 and the connecting groove 603, and the mutual limitation of the slider 802 and the slide groove 801, the support block 203 can be stably moved at the top end of the base 101.

[0030] Among them, the extrusion mechanism includes an extrusion block 701 fixedly connected to the front surface of the fixed plate 601. A first inclined surface 702 is provided at the bottom end of the extrusion block 701, and a second inclined surface 703 is provided at the top end of the horizontal pulling block 502. When the horizontal pulling block 502 moves, due to the fixation of the extrusion block 701, the first inclined surface 702 will extrude the second inclined surface 703, so that the horizontal pulling block 502 can be stably stuck inside the card slot 501, ensuring that the horizontal pulling block 502 can be stably stuck inside the card slot 501 when moving to drive the support block 203 to move.

[0031] Among them, the connection mechanism includes a U-shaped block 901 inserted into the output end of the second cylinder 503. A connection block 902 is fixedly connected to one side of the horizontal pulling block 502, and the connection block 902 is rotatably connected to the inner wall of the U-shaped block 901. Through the rotational setting of the connection block 902, when the first inclined surface 702 extrudes the second inclined surface 703, the horizontal pulling block 502 can move downward, thus ensuring the stability of the movement of the horizontal pulling block 502.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
