DETAILED DESCRIPTION

[0022] It should be noted that the embodiments and the features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0024] Please refer to Figures 1-5 The present application provides the following technical solutions:

[0025] Embodiment one, refer to Figures 1-5The utility model provides a clamp for transformer part production, including lathe 1, the top of axial direction of lathe 1 is provided with bearing plate 2 symmetrically, the top of bearing plate 2 is provided with stagnation platform 3, still be provided with fixed plate 4 between stagnation platform 3, the bottom of fixed plate 4 is provided with rotary motor 5, the output of rotary motor 5 is provided with rotating shaft 51, the one end away from rotary motor 5 of rotating shaft 51 is provided with rotating plate 52, the both sides of rotating plate 52 radial direction are provided with movable element 6 symmetrically, and the both ends of movable element 6 are provided with clamping piece 7.

[0026] Wherein, through the design of bearing plate 2 and stagnation platform 3, the transformer shell part to be processed can be placed on the stagnation platform 3, so as to facilitate clamping. It should be noted that the length of the transformer shell part is greater than the length of the stagnation platform 3, so the two ends of the transformer shell part will be suspended outside the stagnation platform 3.

[0027] When the transformer shell part needs to be clamped, the rotary motor 5 is started, the output end drives the rotating shaft 51 to rotate, so that the rotating plate 52 also rotates synchronously. In this process, because the rotating plate 52 is a four-corner star type, the movable elements 6 on both sides will move in opposite directions, and the corresponding movable element 6 on one end will approach the corresponding stagnation platform 3, and the two movable elements 6 will also approach each other, so that the movable element 6 can clamp the outer wall of one end of the transformer shell part on the corresponding stagnation platform 3 through the clamping piece 7, thereby achieving the purpose of clamping and fixing.

[0028] If the part clamped by the clamping piece 7 also needs to be processed, the transformer shell part can be loosened and placed back on the corresponding stagnation platform 3, and the rotary motor 5 is started to make the rotating shaft 51 and the rotating plate 52 rotate in the opposite direction. The working principle is the same as that of forward rotation, which will not be described in detail here. In this way, the movable element 6 can clamp the other end of the transformer shell part on the corresponding stagnation platform 3 through the clamping piece 7. This avoids the problem that the part that needs to be processed is exactly the part clamped by the mechanism, so manual adjustment is needed before the work can continue. This improves the processing quality of the shell part and the processing efficiency of the shell part.

[0029] Referring to Figures 1-5 Further, the bearing plate 2 is inverted T-shaped, and the top of the stagnation platform 3 is provided with a stagnation groove 31, which is arc-shaped.

[0030] Through the design of the arc-shaped stagnation groove 31, when the transformer shell part is placed in the stagnation groove 31, the displacement and rolling of the transformer shell part can be reduced, the limiting effect is achieved, and the processing quality of the shell part is improved.

[0031] Referring to Figures 1-5Further, the bottom ends of the fixed plate 4 in the axial direction are symmetrically provided with telescopic rods 41, and the ends of the telescopic rods 41 away from the fixed plate 4 are connected to the top of the machine tool 1; the output end of the rotating motor 5 penetrates the top of the fixed plate 4 and is connected to the end of the rotating shaft 51 away from the rotating plate 52, and the rotating plate 52 is in the shape of a four-pointed star.

[0032] The telescopic rods 41 are started, and the telescopic ends of the telescopic rods 41 can push the fixed plate 4 to move upward or downward, so that the movable part 6 and the clamping part 7 are flush with the height of the transformer shell part to be processed, which is beneficial to clamping.

[0033] Referring to Figures 1-5 Further, the outer wall of the fixed plate 4 in the circumferential direction is further provided with an inner ring 8, the inner ring 8 is in an irregular shape, the end of the inner ring 8 close to the fixed plate 4 is recessed, and the bottom ends of the inner ring 8 are provided with ear plates 81; the outer wall of the inner ring 8 is further provided with an outer ring 9, a rail groove 91 is arranged between the inner ring 8 and the outer ring 9, the bottom ends of the outer ring 9 are connected to the top of the corresponding ear plates 81, and the outer ring 9 and the inner ring 8 are in the same shape.

[0034] The movable part 6 slides along the track direction of the rail groove 91 between the outer ring 9 and the inner ring 8, and because the end of the inner ring 8 and the outer ring 9 close to the fixed plate 4 is recessed, the two movable parts 6 are close to each other in the axial direction M and are displaced in opposite directions in the radial direction N during the sliding process.

[0035] Referring to Figures 1-5 Further, the movable part 6 includes a movable plate 61, a movable strip 62 arranged on one side of the movable plate 61, a main pulley 63 rotatably connected to the bottom of the movable strip 62, a rotating strip 64 symmetrically arranged in the axial direction on the side of the movable plate 61 away from the movable strip 62, and a secondary pulley 65 rotatably connected to one end of the bottom of the rotating strip 64; the movable plate 61 and the movable strip 62 are vertically distributed, the main pulley 63 can slide in the rail groove 91, the top ends of the movable plate 61 are further provided with sliding grooves 66, the secondary pulley 65 can slide in the corresponding sliding groove 66, and the end of the rotating strip 64 away from the secondary pulley 65 is rotatably connected to the corresponding four-pointed bottom of the rotating plate 52.

[0036] When the rotating plate 52 rotates, due to the four-corner star type of the rotating plate 52, two corners on the same side of the rotating plate 52 drive two rotating strips 64 on the same side to rotate synchronously, so that the secondary pulleys 65 slide in the corresponding sliding grooves 66, and in the sliding process, the two secondary pulleys 65 pull the corresponding movable plates 61 and movable strips 62 to move synchronously, so that the primary pulleys 63 can slide along the track direction of the rail groove 91. Due to the recesses of the inner ring 8 and the outer ring 9 near the end of the fixed plate 4, the two primary pulleys 63 and the two movable plates 61 move close to each other in the axial direction M and slide in opposite directions in the radial direction N during the sliding process, and the clamping part 7 also moves synchronously to clamp one end of the outer wall of the transformer shell part on the corresponding retention table 3.

[0037] Referring to Figures 1-5 Further, the clamping part 7 comprises a clamping cylinder 71 and a clamping plate 72 symmetrically arranged at the clamping end of the clamping cylinder 71; one end of the clamping cylinder 71 away from the clamping plate 72 is connected to one end of the corresponding movable plate 61.

[0038] The clamping cylinder 71 is started to drive the clamping plate 72 to rotate, so that the two clamping plates 72 can clamp the outer wall of the corresponding transformer shell part.

[0039] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.
