[0028] Figure 1This is a schematic structural diagram of a motor guide bar grinding device according to an embodiment of the present utility model. Figure 1 As shown, and reference Figures 2 to 5 The present invention provides a motor guide bar grinding device, which includes a mounting frame 2, a conveyor 1, a grinding device 4, and a lifting device 5. The mounting frame 2 includes a base plate 201 and a back plate 202. The conveyor 1 and back plate 202 are mounted on the base plate 201, with the back plate 202 located at the center and rear of the conveyor 1.

[0029] Specifically, the conveying device 1 includes a conveying motor 101 , an active conveying roller 102 , a conveying belt 103 , an adjusting slide 104 , a driven conveying roller 105 , and a conveying adjusting screw 106 .

[0030] Furthermore, a driving conveying roller 102 is installed at the left end of the conveyor 1, and a conveying motor 101 is installed coaxially. The transmission motor is located behind the driving conveying roller 102 and is used to control the rotation of the driving conveying roller 102. A driven conveying roller 105 and an adjustment slide 104 are installed at the right end of the conveyor 1.

[0031] Furthermore, when the active conveying roller 102 rotates, the driven conveying roller 105 is driven to rotate together. A conveyor belt 103 is installed on the active conveying roller 102 and the driven conveying roller 105.

[0032] Furthermore, the adjustment slide 104 is provided with a groove, into which the driven conveyor roller 105 is slidably mounted. A conveyor adjustment screw 106 is used to adjust the position of the driven conveyor roller 105 on the adjustment slide 104, thereby adjusting the length of the conveyor device 1. The user can adjust the length of the conveyor adjustment screw 106 to the length of the guide strip to be polished, thereby adjusting the conveying length of the conveyor device 1. This allows for convenient and simple adjustment.

[0033] In some embodiments of the present invention, Figures 1 to 2 As shown, the grinding device 4 is mounted in the middle of the back plate 202 in an upward and downward sliding manner, and a grinding gap 7 is formed between the grinding device 4 and the conveying device 1. The grinding gap 7 is used for polishing when the guide bar to be polished passes through.

[0034] Specifically, the grinding device 4 includes a first roller 401 and a thread rolling wheel 402 .

[0035] Specifically, the thread rolling wheel 402 is a black diamond thread rolling wheel.

[0036] Furthermore, the first roller 401 is installed in the middle of the back plate 202 , and the thread rolling wheel 402 is sleeved on the first roller 401 .

[0037] Furthermore, a grinding motor 6 is coaxially mounted on the first roller 401 for driving the first roller 401 to rotate.

[0038] Furthermore, the grinding motor 6 is connected to the lifting device 5 via a connector 504. The lifting device 5 is used to control the vertical lifting of the grinding motor 6, thereby driving the vertical lifting of the first roller 401, thereby adjusting the size of the grinding gap 7. This technical solution can remove burrs on guide bars of different specifications and can also perform wire drawing on the surfaces of guide bars of different specifications, with strong applicability.

[0039] In other embodiments of the present invention, Figure 3 As shown, the grinding device 4 includes a first roller 401, a second roller 403, a grinding motor 6, and a grinding belt 404. The first roller 401 and the second roller 403 are rotatably mounted on the mounting frame 2. The axes of the first roller 401 and the second roller 403 are located in the same vertical plane, and the second roller 403 is located above the first roller 401. The grinding motor 6 is connected to the first roller 401 and is used to drive the first roller 401 to rotate. The grinding belt 404 is mounted on the first roller 401 and the second roller 403, and forms a grinding gap 7 between it and the conveyor 1. This technical solution is used to polish the surface of the guide bar to be polished, which can significantly reduce the cost of manual polishing and improve the efficiency of the guide bar polishing work.

[0040] The motor guide bar grinding device also includes a support plate 405, which is fixed to the back plate 202 via an iron sheet. The support plate 405 is located inside the grinding belt 404 and is parallel to the grinding belt 404, with a clearance fit between the support plate 405 and the grinding belt 404. During operation, the user holds the end of the guide bar against the grinding belt 404 above the support plate 405. The support plate 405 supports the grinding belt 404 while grinding the guide bar end, thereby facilitating grinding the end of the guide bar to be ground.

[0041] In some embodiments of the present invention, Figure 4 As shown, the lifting device 5 includes a slide 502, a valve wheel 503, a connector 504, a base 501 and a screw nut assembly 505. The base 501 is installed on the base plate 201, and the valve wheel 503 is installed on the top of the base 501. The base 501 includes a first slide 506 extending in the vertical direction, and the slide 502 is slidably arranged on the first slide 506. The screw nut assembly 505 is located inside the base 501 and is used to control the vertical lifting and lowering of the slide 502 on the base 501. The slide 502 is connected to the grinding motor 6 through the connector 504. When the grinding device 4 is in use, the user rotates the valve wheel 503 to make the nut on the screw nut assembly 505 rise or fall, thereby driving the slide 502 and the grinding motor 6 to rise and fall vertically, and then making the first roller 401 rise and fall. The lifting device 5 can meet the needs of grinding guide bars of different specifications and has strong applicability.

[0042] Specifically, there are multiple options for the screw nut assembly 505. For example, the screw nut assembly 505 can be replaced with a hydraulic assembly or a chain-type lifting assembly.

[0043] In some embodiments of the present invention, Figure 5 As shown, a motor guide bar grinding device further includes two clamping assemblies 3. The two clamping assemblies 3 are mounted on the back plate 202 and are located on the left and right sides of the grinding device 4. They are clearance-matched with the conveying device 1 and are used to clamp the workpiece to be ground when the workpiece passes through the grinding gap 7.

[0044] Specifically, the clearance fit between the pressing component 3 and the conveying device 1 specifically refers to the clearance fit between the pressing surface of the pressing component 3 and the conveying plane of the conveying device 1 .

[0045] Specifically, the pressing assembly 3 includes a fixing block 302 , a pressing roller 301 , a telescopic rod 307 , an adjusting member 304 and a limiting member 303 .

[0046] Furthermore, the fixing block 302 and the limiting member 303 are fixedly mounted on the mounting frame 2 .

[0047] Furthermore, the fixing block 302 includes a second slideway 309 extending in a vertical direction, and the pressing roller 301 is slidably mounted on the second slideway 309 .

[0048] Furthermore, the telescopic rod 307 is vertically arranged, the telescopic rod 307 is sleeved inside the spring 308, and one end of the bottom is fixed to the pressing roller 301, and one end of the top of the telescopic rod 307 passes through the limiter 303 and is connected to the adjusting member 304. The limiter 303 is used to limit the telescopic rod 307 from extending and retracting in the vertical direction.

[0049] Specifically, the adjusting member 304 includes an adjusting screw 306 and an adjusting nut 305 .

[0050] Furthermore, the adjusting screw rod 306 is fixedly connected to one end of the top of the telescopic rod 307. The adjusting nut 305 is threadedly connected to the adjusting screw rod 306 for adjusting the length of the adjusting screw rod 306 to meet the requirements of different specifications of guide bars when grinding by the pressing assembly 3.

[0051] Working principle: When the grinding device 4 consists of a first roller 401 and a thread rolling wheel 402, the guide bar to be ground is placed on the conveyor belt 103, is pressed when passing through the clamping assembly 3, and then passes through the grinding gap 7 formed between the thread rolling wheel 402 and the conveyor belt 103, thereby removing burrs on the guide bar to be ground and performing wire drawing on the surface of the guide bar to be ground. When the thickness of the guide bar is relatively large, the valve wheel 503 on the rotating lifting device 5 causes the lifting mechanism inside the base 501 to drive the slide 502 to rise, thereby raising the height of the first roller 401. When the guide bar to be ground passes through the grinding gap 7 formed between the first roller 401 and the conveyor device 1, it can be well ground. Similarly, when the thickness of the guide bar is relatively small, the height of the first roller 401 is lowered by the lifting device 5, thereby reducing the size of the grinding gap 7.

[0052] When the grinding device 4 comprises a first roller 401, a second roller 403, a support plate 405, and a conveyor belt 103, the guide bar to be ground is placed on the conveyor belt 103, is compressed when passing through the pressing assembly 3, and then passes through the grinding gap 7 formed between the grinding belt 404 and the conveyor belt 103, thereby polishing and grinding the surface of the guide bar to be ground. Furthermore, the end of the handheld guide bar is pressed against the grinding belt 404 above the support plate 405. The support plate 405 is used to support the grinding belt 404 when the grinding belt 404 grinds the end of the guide bar, thereby grinding the end of the guide bar to be ground, which is convenient for operation. When the thickness of the guide bar is large or small, the size of the grinding gap 7 is adjusted by the lifting device 5. The specific working principle is the same as when the grinding device 4 comprises a first roller 401 and a thread rolling wheel 402.

[0053] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention.
