Detailed Embodiments

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1-6 , a turning fixture provided by the present utility model includes: a turntable 1 and a groove 2 formed on the outer wall of one side of the turntable 1. It further includes: a conductive slip ring 3 installed on the outer wall of one end of the turntable 1, an adjustment assembly 4 installed on the top outer wall of the turntable 1, and a pushing assembly 5 installed on the outer wall of one side of the turntable 1. Both ends of the adjustment assembly 4 are installed with clamping plates 6, and rotating rods 7 are rotatably installed on the outer walls of one sides of the two clamping plates 6. Fixing frames 8 are fixed at the opposite ends of the two rotating rods 7, and inserting openings 9 are formed on the outer walls of one sides of the two rotating rods 7. Sliding grooves 10 are formed on the top outer walls of the two clamping plates 6, and elastic force assemblies 11 are installed on the inner walls of the two sliding grooves 10. Insertion plates 12 are installed on the two elastic force assemblies 11, and fixing openings 13 are formed on the two clamping plates 6.

[0022] It should be noted here that: the turntable 1 can be installed on a lathe, and the double-headed workpiece 14 can be placed between the two fixing frames 8. By driving the two clamping plates 6 to approach each other through the adjustment assembly 4, the two fixing frames 8 are driven to approach each other to clamp and fix the double-headed workpiece 14. After fixing, the upper and lower ends of the pushing assembly 5 can be moved up and down respectively. During the movement of the upper and lower ends of the pushing assembly 5, the two insertion plates 12 can be respectively pushed into the two fixing openings 13, thereby fixing the two rotating rods 7. At this time, the double-headed workpiece 14 is completely fixed. The lathe can drive the fixture and the double-headed workpiece 14 to rotate for turning. After turning one end of the double-headed workpiece 14, the upper and lower ends of the pushing assembly 5 can be reset. At this time, the two insertion plates 12 are respectively reset under the action of the two elastic force assemblies 11 and move out of the two fixing openings 13 respectively. At this time, the double-headed workpiece 14 can be rotated to drive the two rotating rods 7 to rotate, so as to turn the double-headed workpiece 14 back and forth, which is convenient for turning the other end of the double-headed workpiece 14. After the replacement, the upper and lower ends of the pushing assembly 5 can be moved up and down respectively again, and the two insertion plates 12 are pushed into the two fixing openings 13, thereby fixing the two rotating rods 7, making it more convenient to turn the double-headed workpiece 14 back and forth without frequently disassembling the double-headed workpiece 14.

[0023] In a preferred embodiment, the adjustment assembly 4 includes a motor 401, a bidirectional threaded rod 402 connected to the bottom of the output shaft of the motor 401, and moving blocks 403 screwed to both ends of the bidirectional threaded rod 402.

[0024] It should be noted here that the motor 401 can drive the bidirectional threaded rod 402 to rotate, enabling the two moving blocks 403 to approach each other, and further driving the two clamping plates 6 to approach each other.

[0025] In a preferred embodiment, the jacking assembly 5 includes a mounting plate 501, electric push rods 502 mounted on the outer walls on the upper and lower sides of the mounting plate 501, and a top ball 503 fixed to the ends of the piston rods of the two electric push rods 502.

[0026] It should be noted here that the piston rod of the electric push rod 502 extends outwards, driving the top ball 503 to move. During the movement of the top ball 503, it contacts the insertion plate 12 and jacks the insertion plate 12 to move, causing one end of the insertion plate 12 to insert into the fixing port 13.

[0027] In a preferred embodiment, the elastic force assembly 11 includes a sliding rod 1101, a spring 1102 sleeved on one end of the sliding rod 1101, and a slider 1103 sleeved on the other end of the sliding rod 1101.

[0028] It should be noted here that during the movement of the insertion plate 12, it drives the slider 1103 to move, thereby squeezing the spring 1102. When the piston rod of the electric push rod 502 contracts and resets, the insertion plate 12 loses the extrusion force of the top ball 503 and automatically resets under the action of the spring 1102.

[0029] In a preferred embodiment, the two clamping plates 6 are respectively fixed to the outer walls of the two moving blocks 403.

[0030] It should be noted here that the two moving blocks 403 can drive the two clamping plates 6 to move respectively.

[0031] In a preferred embodiment, the two electric push rods 502 and the motor 401 are both connected to the slip ring rotor in the conductive slip ring 3 through wires.

[0032] It should be noted here that when the two electric push rods 502 and the motor 401 rotate with the turntable 1, there will be no problem of wire entanglement.

[0033] Working principle: The turntable 1 can be installed on a lathe. The double-headed workpiece 14 can be placed between two holders 8. The bidirectional threaded rod 402 can be driven to rotate by the motor 401, so that the two moving blocks 403 approach each other, and then drive the two clamping plates 6 to approach each other, and further drive the two holders 8 to approach each other to clamp and fix the double-headed workpiece 14. After fixing, the piston rods of the two electric push rods 502 can extend outwards, and then drive the two top balls 503 to move. During the movement of the two top balls 503, they contact the two insertion plates 12 respectively, and push the two insertion plates 12 to move, and can respectively push the two insertion plates 12 into the two fixing ports 13, so as to fix the two rotating rods 7. At this time, the double-headed workpiece 14 is completely fixed, and the lathe can drive the fixture and the double-headed workpiece 14 to rotate for turning;

[0034] After turning one end of the double-headed workpiece 14, the piston rods of the two electric push rods 502 can contract and reset. During the movement of the insertion plate 12, it drives the slider 1103 to move, and then compresses the spring 1102. When the piston rod of the electric push rod 502 contracts and resets, the insertion plate 12 loses the extrusion force of the top ball 503 and automatically resets under the action of the spring 1102. At this time, the double-headed workpiece 14 can be rotated to drive the two rotating rods 7 to rotate, so as to turn the double-headed workpiece 14 back and forth, which is convenient for turning the other end of the double-headed workpiece 14. After the adjustment, the piston rods of the two electric push rods 502 can extend outwards again to push the two insertion plates 12 into the two fixing ports 13, so as to fix the two rotating rods 7. The back-and-forth adjustment of the double-headed workpiece 14 is more convenient, and there is no need to frequently disassemble the double-headed workpiece 14.

[0035] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
