The design limits the stop plate 71 by rotating the threaded rod 75 in the pair of limiting assemblies 7 arranged symmetrically, thereby limiting the clamping plate 3 connected with the guide block 5, which can avoid the phenomenon of clamping injury of the clamping plate 3 to the accessory, enhance the anti-clamping injury effect, avoid the phenomenon of waste of a large amount of time for subsequent maintenance due to clamping injury of the accessory, and further improve the processing efficiency; one of the pair of limiting assemblies 7 is arranged on the opposite side of the bottom plate 1, thereby not affecting the clamping of the accessory on the top of the bottom plate 1 and not existing interference.
[0031] Referring to Figure 1 and Figure 2One end of the threaded rod 75 is provided with a limiting disc 73 between the pair of stop plates 71, the connecting part of the limiting disc 73 and the threaded rod 75 is provided with a bearing 74, and the other end of the threaded rod 75 is provided with a force applying handle 76. The design facilitates force applying to the threaded rod 75 through the force applying handle 76, the threaded connection between the threaded rod 75 and the stop plate 71 facilitates the threaded rod 75 to drive the limiting disc 73 to rotate and move transversely at the same time, so as to adjust the distance between the limiting disc 73 and the stop plate 71, and further adjust the limiting distance of the clamping plate 3, so as to ensure the stable clamping of the clamping plate 3 to the fittings and avoid clamping injury to the fittings.
[0032] With reference to Figure 2 and Figure 7 , the side wall of the threaded rod 75 is sleeved with a stop nut 4 which is attached to the stop plate 71, a plurality of link holes 9 are formed in the side wall of the stop nut 4, and one of the link holes 9 is internally provided with a force applying column 10. The design improves the stability of the connecting part of the threaded rod 75 and the stop plate 71 through the attachment of the stop nut 4 and the stop plate 71, and ensures the stability of the limiting of the clamping plate 3; the force applying column 10 is inserted into the link hole 9 and can be replaced between the link holes 9, which facilitates force applying to the stop nut 4 to make it rotate along the side wall of the threaded rod 75 and move transversely.
[0033] With reference to Figure 2 , Figure 3 and Figure 4 , the stop plate 71 comprises a moving block 711 which is arranged on the side wall of the guide block 5 and penetrates and exposes the moving groove 72, and the side of the moving block 711 away from the guide block 5 is provided with a limiting block 712 which is attached to the side wall of the bottom plate 1.
[0034] The threaded rod 75 penetrates the side wall of the limiting block 712, and the stop nut 4 is attached to the side wall of the limiting block 712. The design improves the stability of the transverse movement of the moving block 711 through the movement of the moving block 711 in the stop plate 71 along the moving groove 72; the attachment of the limiting block 712 to the side wall of the bottom plate 1 ensures that the limiting block 712 can move along the side wall of the bottom plate 1, and improves the stability of the transverse movement of the stop plate 71; wherein the vertical sectional area of the moving block 711 is smaller than that of the limiting block 712, which ensures the stability of the transverse movement of the stop plate 71.
[0035] With reference to Figure 1 , Figure 3 , Figure 4 and Figure 6The bottom plate 1 is internally provided with a communication groove 12 located below the guide groove 6 and communicated with the guide groove 6, the side wall of the bottom plate 1 is provided with an inclined groove 8 communicated with the communication groove 12 and inclined downward, and the cross-sectional area of the guide groove 6 is larger than the cross-sectional area of the communication groove 12. The design makes the inclined groove 8 communicated with the guide groove 6 through the communication groove 12, facilitates the debris generated during the processing such as polishing of the fittings to enter the inside of the inclined groove 8 and flow out from the inclined groove 8 of the side wall of the bottom plate 1, and avoids the guide block 5 from entering the inside of the communication groove 12 through the cross-sectional area of the guide groove 6 larger than the cross-sectional area of the communication groove 12, thereby ensuring the stability of the transverse movement of the guide block 5 along the guide groove 6.
[0036] With reference to Figure 1 and Figure 5 , the bottom plate 1 is provided with a scale line 11 near one side of the limiting block 712. The design can ensure that the stop plates 71 in the pair of limiting assemblies 7 are adjusted to the same position through the scale line 11, improves the stability of the limiting of the clamping plate 3, and facilitates the placement of the fittings at the appropriate position on the top of the bottom plate 1 through the observation of the scale line 11, so that the clamping plate 3 is driven by the hydraulic cylinder 2 to clamp the fittings; wherein the clamped fittings are square fittings, and when other shaped fittings need to be clamped, appropriate clamping plates 3 are replaced for matching clamping according to the requirements.
[0037] With reference to Figures 1-7 , as an embodiment of the utility model: when the fittings need to be clamped, the worker places the fittings at the appropriate position on the top of the bottom plate 1 through the observation of the scale line 11, and then drives the clamping plate 3 to clamp the fittings through the work of the hydraulic cylinder 2, when the clamping of the fittings is stable, the force handle 76 in the pair of limiting assemblies 7 is rotated to drive the threaded rod 75 to rotate, the threaded rod 75 is threadedly connected with the stop plate 71 to drive the limiting disc 73 to move transversely and contact with the stop plate 71, thereby completing the limiting adjustment of the fittings.
[0038] When the same specification fittings are clamped, the clamping plate 3 can be limited under the action of the limiting disc 73 contacting with the stop plate 71, so that when the same specification fittings are continuously processed and clamped, the clamping plate 3 is prevented from moving continuously to clamp the fittings, the anti-clamping effect is enhanced, the clamping efficiency is high, and the practicability of the utility model is improved.
