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 making creative efforts belong to the protection scope of the present invention.

[0026] The following gives specific embodiments.

[0027] Please refer to Figures 1-5 , the present invention provides a clamping mechanism for rail processing, including a processing seat 1; a cylinder 2 is fixedly connected to the top of the processing seat 1, and the output end of the cylinder 2 is fixedly connected to a clamping plate 3; a limit block 4 is fixedly connected to one side surface of the clamping plate 3, and the top of the limit block 4 is rotatably connected to a fixed block 5 through a rotating shaft;

[0028] A positioning mechanism 6 is provided on the clamping plate 3. The positioning mechanism 6 includes a positioning groove 61 formed on one side surface of the clamping plate 3. A pulley 62 is rotatably connected to the inner bottom wall of the positioning groove 61 through a rotating shaft. The top end of the pulley 62 is fixedly connected to a transmission rod 63. A first gear 64 is fixedly connected to the outer wall of the transmission rod 63. An internal gear 65 is slidably connected to the outer wall of the transmission rod 63. A positioning block is fixedly connected to the inner side wall of the positioning groove 61. The bottom of the internal gear 65 is elastically connected to the top end of the positioning block through a first spring 66. The top of the internal gear 65 is fixedly connected to a pressing block. The top end of the pressing block penetrates through the clamping plate 3 and is fixedly connected to a pressing plate 67. During operation, when the internal gear 651 contacts the first gear 64, the internal gear 65 is meshed with the first gear 64. Through the setting of the positioning mechanism 6, while facilitating the clamping of the guide rail, it is convenient for the movement of the guide rail and ensures that the guide rail will not deviate during the movement. That is, the guide rail is moved to the processing seat 1 and placed between the two clamping plates 3. The cylinder 2 is started to drive the clamping plate 3 to move to clamp and position the guide rail. Pressure is applied to the pressing plate 67, so that the pressing plate 67 drives the internal gear 65 to move downward through the pressing block, so that the internal gear 65 contacts the first gear 64 and limits the rotation of the first gear 64 and the pulley 62. At the same time, the fixing block 5 is rotated so that the bottom of the fixing block 5 is lapped with the top of the pressing plate 67, and then the guide rail can be processed. When it is necessary to move the guide rail to the next processing location, the fixing block 5 can be rotated to release the limit on the pressing plate 67. Under the pressure of multiple first springs 66, the pressing plate 67 drives the internal gear 65 to reset, releasing the rotation limit on the first gear 64 and the pulley 62. At this time, the two clamping plates 3 cooperate with multiple equidistantly distributed pulleys 62 to clamp and position the guide rail, but the pulley 62 can rotate, so that the guide rail can move between the two clamping plates 3. When the guide rail moves to a suitable position, the pressing plate 67 is pressed again, and the fixing block 5 is rotated to the top of the pressing plate 67 to position the movement of the guide rail and process the guide rail.

During operation, through the setting of the auxiliary groove and the auxiliary roller 7, it is convenient to assist the movement of the guide rail and avoid the guide rail being too heavy and having too large a frictional force with the processing seat 1, which is not convenient for movement.

[0030] Further, as Figure 2 and Figure 5As shown, the processing seat 1 is provided with an adjustment groove 8, the inner side wall of the auxiliary groove is provided with a through groove connected to the adjustment groove 8, the auxiliary roller 7 is fixedly connected with a driving rod on one side close to the through groove, one end of the driving rod extends into the adjustment groove 8 and is fixedly connected with the second gear 10, a rack 9 is slidably connected in the adjustment groove 8, the rack 9 is meshed with the second gear 10, one side of the rack 9 is fixedly connected with a toggle rod, and the other end of the toggle rod penetrates the processing seat 1 and communicates with the outside. During operation, through the arrangement of the driving rod, the second gear 10, the rack 9 and the toggle rod, the auxiliary roller 7 can be rotated and positioned when the guide rail is clamped and positioned as needed, and when the guide rail is not clamped and positioned, the toggle rod can be pushed to drive the rack 9 to move, so that the rack 9 is away from the second gear 10, and the rotation limit of the second gear 10 and the auxiliary roller 7 is released, and when the guide rail needs to be clamped and positioned, the toggle rod can be pulled back, the rack 9 is reset to limit the rotation of the second gear 10, so that multiple equally distributed auxiliary rollers 7 do not rotate.

[0031] Further, such as Figure 1 As shown, one end of the toggle rod located at the outside is fixedly connected to a toggle plate 11, and an anti-slip pattern is arranged on the outer wall of the toggle plate 11. During operation, the arrangement of the toggle plate 11 can facilitate the simultaneous application of force to multiple toggle rods.

[0032] Further, such as Figure 2 and Figure 4 As shown, a groove is provided at the top of the pressing plate 67, an auxiliary block 12 is slidably connected in the groove, a first magnetic block is fixedly connected to the bottom of the auxiliary block 12, and a second magnetic block 13 is fixedly connected to the inner bottom wall of the groove. During operation, through the arrangement of the groove, the auxiliary block 12 and the first magnetic block, an engaging groove matching the auxiliary block 12 is provided at the bottom of the fixed block 5, and the top of the auxiliary block 12 is arranged in a semicircular shape, so that when the fixed block 5 is overlapped on the top of the pressing plate 67, the fixed block 5 can be positioned to avoid the self-displacement of the fixed block 5 due to vibration during the processing of the guide rail.

[0033] Further, such as Figure 2 and Figure 3 As shown, the top of the clamping plate 3 is fixedly connected with a guide rod 14, and the top of the guide rod 14 passes through the pressing plate 67. During operation, the pressing plate 67 can be moved and guided by the setting of the guide rod 14 to avoid the pressing plate 67 from deflecting when the pressing plate 67 is pressed.

[0034] Further, such as Figure 1 and Figure 2 As shown, the outer wall of the fixed block 5 is provided with anti-skid patterns, and the top of the pressing plate 67 is provided with anti-skid patterns. During operation, the anti-skid patterns are provided on the outer wall of the fixed block 5 and the top of the pressing plate 67 to improve friction.

[0035] Working principle: Move the guide rail onto the processing seat 1 and place it between two clamping plates 3. Start the cylinder 2 to drive the clamping plates 3 to move and clamp and position the guide rail. Apply pressure to the pressing plate 67, so that the pressing plate 67 drives the internal gear 65 to move downward through the pressing block, making the internal gear 65 contact the first gear 64 and limit the rotation of the first gear 64 and the pulley 62. At the same time, rotate the fixing block 5 so that the bottom of the fixing block 5 overlaps with the top of the pressing plate 67, and then the guide rail can be processed. When it is necessary to move the guide rail for the next processing, the fixing block 5 can be rotated to release the limit on the pressing plate 67. Under the pressure of multiple first springs 66, the pressing plate 67 drives the internal gear 65 to reset, releasing the rotation limit on the first gear 64 and the pulley 62. At this time, the two clamping plates 3 cooperate with multiple equidistantly distributed pulleys 62 to clamp and position the guide rail, but the pulley 62 can rotate, enabling the guide rail to move between the two clamping plates 3. When the guide rail moves to a suitable position, press the pressing plate 67 again and rotate the fixing block 5 to the top of the pressing plate 67 to position the movement of the guide rail and process the guide rail.
