[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Embodiment 1:

[0029] like Figure 1-4 As shown, a saw chain grinding positioning device comprises a bearing plate 1 and a supporting leg 2 fixedly connected to the bottom of the bearing plate 1 by bolts.

[0030] Two groups of symmetrically arranged clamping assemblies 3 are provided on the top of the supporting plate 1, and a guide assembly 5 for providing support and guidance for the chain is provided between the two groups of clamping assemblies 3. The clamping assembly 3 includes a guide groove 6 opened on the top of the supporting plate 1 and a clamping plate 9 that is coupled to the guide groove 6 through a transmission assembly, and an anti-slip pad 10 is fixedly bonded to the outer wall of one side of the clamping plate 9.

[0031] The two groups of clamping plates 9 and anti-skid pads 10 move in opposite directions along the two guide grooves 6 respectively through a group of transmission components. When the two anti-skid pads 10 are opposite to each other, the distance between the two clamping plates 9 is small enough to clamp the chain. Then the clamping plates 9 and anti-skid pads 10 drive the chain to move horizontally for a distance, and move the chain blade to the grinder for grinding. During the grinding process, the clamping plates 9 and anti-skid pads 10 still keep the chain clamped. After the grinding is completed, the clamping plates 9 and anti-skid pads 10 continue to move along the guide groove 6, so that the distance between the two clamping plates 9 gradually increases, thereby losing the clamping of the chain, and repeating this process.

[0032] The device is provided with two sets of guide grooves 6, a clamping plate 9 and an anti-skid pad 10. The clamping plate 9 and the anti-skid pad 10 cooperate to clamp the chain, and at the same time drive the chain to move to the grinder for grinding. The chain can also be clamped during grinding, thereby simplifying the overall manual operation steps and improving the grinding efficiency on the one hand, and ensuring the stability of the chain during grinding and ensuring the grinding effect on the other hand.

[0033] like Figure 2 As shown, the transmission assembly includes a connecting plate 11 and two symmetrically arranged guide wheels 13 and an axle 14. The connecting plate 11 is fixedly connected to the bottom of the clamping plate 9 through two axles 14. The guide wheel 13 rolls on the inner wall of the guide groove 6, and the guide wheel 13 is rotatably connected to the outer wall of the axle 14.

[0034] The inner wall of the supporting plate 1 at the guide groove 6 is rotatably connected to the sleeve rod 7 through the axis 3 16, and the inner wall of the sleeve rod 7 is slidably matched with the slide rod 8. The opposite sides of the sleeve rod 7 and the slide rod 8 are buckled with a spring 15, and the end of the slide rod 8 away from the sleeve rod 7 is rotatably matched with the top of the connecting plate 11 through the axis 12.

[0035] One end of the shaft 3 16 is fixedly connected to a motor 17 via a coupling, and the motor 17 is fixedly connected to the bottom of the bearing plate 1 via bolts.

[0036] The starting motor 17 drives shaft three 16 to drive the sleeve rod 7 and the slide rod 8 to rotate along the axis of shaft three 16. The slide rod 8 uses shaft one 12 to drive the connecting plate 11, shaft two 14 and the clamping plate 9 to move. Shaft two 14 drives the guide wheel 13 to roll along the guide groove one 6. Embodiment 2:

[0037] A saw chain grinding positioning device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1 , Figure 3 and Figure 4 As shown:

[0038] The guide assembly 5 includes a sprocket 18 rotatably connected to the inner wall of one side of the carrier plate 1 and a guide plate 19 slidably matched to the inner wall of the other side of the carrier plate 1. The inner wall of the guide plate 19 is provided with a guide groove 20. The chain is placed on the outer wall of the sprocket 18 and the guide groove 20, so as to provide support and guidance for the chain.

[0039] The inner wall of the supporting plate 1 located at the guide plate 19 is provided with an adjustment component 4 for adjusting the position of the guide plate 19, the adjustment component 4 includes an adjustment rod 21, a threaded rod 22 and a sleeve 24, the threaded rod 22 is rotatably connected to the inner wall of the supporting plate 1, the adjustment knob 23 is fixedly connected to one end of the threaded rod 22, and the sleeve 24 is connected to the outer wall of the threaded rod 22 by threads.

[0040] An adjusting rod 21 is fixedly connected to the outer wall of the guide plate 19 , and the other end of the adjusting rod 21 is fixedly connected to the outer wall of the sleeve 24 .

[0041] After placing the chain on the outer wall of the guide groove 20, rotating the adjusting knob 23 drives the threaded rod 22 to rotate, and the sleeve 24 moves along the outer wall of the adjusting knob 23 by means of the thread, thereby using the adjusting rod 21 to drive the guide plate 19 to slide along the inner wall of the supporting plate 1, and the position of the guide plate 19 can be changed, thereby adjusting the tightness of the chain.

[0042] The device is provided with an adjusting rod 21, an adjusting knob 23, a sleeve 24 and an adjusting knob 23. Rotating the adjusting knob 23 drives the threaded rod 22 to rotate. The sleeve 24 and the adjusting rod 21 cooperate to drive the guide plate 19 to slide along the inner wall of the supporting plate 1, thereby changing the position of the guide plate 19, and further adjusting the tightness of the chain to ensure the smooth movement of the chain.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
