Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a clamp for a numerically controlled lathe. Background Art

[0002] CNC machine tools automatically process the parts to be processed according to the pre-compiled processing program. We compile the processing route, process parameters, tool movement trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet according to the instruction code and program format specified by the CNC machine tool. The contents of this program sheet are recorded on the control medium and then input into the CNC device of the CNC machine tool to command the machine tool to process the parts. In addition, matching positioning fixtures need to be used according to the parts being produced and processed, so as to clamp and fix the parts to be processed during the processing of the parts.

[0003] In the prior art, during CNC machine tool processing, a positioning fixture is needed to limit the parts. However, since the overall structure of the positioning fixture is relatively fixed, it is impossible to turn the clamped products and parts. Therefore, it is not convenient to process irregular surfaces or even polyhedrons with multiple faces. At the same time, when the fixture clamps the parts and processes them through a CNC lathe, operations such as turning and drilling are generally involved. These operations can easily lead to excessive local temperatures. Once the temperature is too high, it needs to be cooled. Traditional fixtures do not have auxiliary cooling structures and are generally not very functional. Utility Model Content

[0020] The utility model provides a technical solution: comprising a base component 1, a clamping component 2 is rotatably installed on the top of the base component 1, the base component 1 comprises a T-shaped bottom plate 101, an arc groove 102 is opened on the top surface of the T-shaped bottom plate 101, a tooth body groove 104 is opened in the middle of the arc groove 102, a circular groove is opened on one side of the middle of the T-shaped bottom plate 101, a rotating motor 105 is fixedly embedded in the circular groove, one end of the output shaft of the rotating motor 105 extends into the tooth body groove 104, and a driving gear 106 is fixedly installed on one end of the output shaft of the rotating motor 105;

[0021] The clamping assembly 2 includes a semicircular base 201, a flat plate 202 is fixedly installed on the top surface of the semicircular base 201, a connecting arc-shaped slide plate 203 is fixedly installed on the front and rear parts of the bottom of the semicircular base 201, an arc-shaped tooth plate 204 is fixedly installed on the middle part of the bottom surface of the semicircular base 201, a slide groove is opened on the back side of the flat plate 202, a movable slider 205 is slidably installed in the slide groove, a water pipe 206 is fixedly installed on the back side of the movable slider 205, a screw rod 209 is rotatably installed in the middle part of the flat plate 202, a groove 210 is opened on both sides of the middle part of the top surface of the flat plate 202, a threaded slider 211 is slidably installed in each of the two grooves 210, and a T-shaped clamp plate 212 is fixedly installed on the top of each of the two threaded sliders 211.

[0022] In this embodiment, a water inlet head 207 is fixedly installed at the bottom of the water pipe 206, and a water spray head 208 is fixedly installed at the other end of the water pipe 206. The water source is connected to the water inlet head 207, water enters the water pipe 206 and is transported to the water spray head 208, and the water is sprayed out through the water spray head 208, so that the product can be sprayed with water to cool it down, which is more practical.

[0023] At the same time, an arc-shaped embedded sliding groove 103 is opened at the front and rear parts of the arc-shaped groove 102, and the two connecting arc-shaped slide plates 203 correspond one-to-one to the two arc-shaped embedded sliding grooves 103. The connecting arc-shaped slide plates 203 are slidably installed in the arc-shaped embedded sliding grooves 103, so that the semicircular base 201 can be rotatably installed in the arc-shaped groove 102.

[0024] The arc-shaped tooth plate 204 corresponds to the tooth body groove 104, and the arc-shaped tooth plate 204 is meshed and connected with the driving gear 106. Since the driving gear 106 is meshed and connected with the arc-shaped tooth plate 204 fixedly installed on the bottom surface of the semicircular base 201, the rotation of the driving gear 106 can drive the arc-shaped tooth plate 204 to rotate, and then drive the semicircular base 201 to rotate. Finally, the rotation of the semicircular base 201 can drive the flat plate 202 and the clamped product on the flat plate 202 to rotate.

[0025] The two T-shaped clamps 212 are symmetrically arranged, and the screw 209 is a double-ended threaded rod, and the thread patterns at both ends are oppositely arranged. Since the screw 209 is a double-ended threaded rod, the T-shaped clamps 212 can be controlled to move closer to or farther away from each other. By controlling the T-shaped clamps 212 to move closer to each other synchronously, the product located between the two T-shaped clamps 212 can be clamped.

[0026] When in use, place the product to be processed between the two T-shaped clamps 212. After placing them, manually rotate the screw 209. The rotation of the screw 209 can drive the two T-shaped clamps 212 to move along the screw 209. Since the screw 209 is a double-headed screw threaded rod, the T-shaped clamps 212 can be controlled to move closer to or farther away from each other. By controlling the T-shaped clamps 212 to move closer to each other synchronously, the product located between the two T-shaped clamps 212 can be clamped. After clamping, when the CNC lathe is processing, the product located on the top surface of the flat plate 202 can be conveniently controlled to rotate, thereby facilitating the processing of the product surface. The specific rotation steps are as follows. The rotation motor 105 can be started, and the rotation motor 105 can drive the output shaft The driving gear 106 fixedly installed at one end rotates. Since the driving gear 106 is meshedly connected with the arc-shaped toothed plate 204 fixedly installed on the bottom surface of the semicircular base 201, the rotation of the driving gear 106 can drive the arc-shaped toothed plate 204 to rotate, and then drive the semicircular base 201 to rotate. Finally, the rotation of the semicircular base 201 can drive the flat plate 202 and the clamped product on the flat plate 202 to rotate. At the same time, the water pipe 206 can be manually moved to the product processing position, and then the water source is connected through the water inlet head 207, and water enters the water pipe 206 and is transported to the water spray head 208, and the water is sprayed out through the water spray head 208, so that the product can be sprayed with water to cool down, which is more practical.

[0027] To sum up, the CNC lathe clamp can clamp the product located between the two T-shaped clamps 212 by controlling the T-shaped clamps 212 to approach each other synchronously. After clamping, when the CNC lathe is processing, the product located on the top surface of the flat plate 202 can be conveniently controlled to rotate, so that the surface of the product can be conveniently processed, which is more practical. At the same time, when the product is processed on the flat plate 202, an external water source is connected through the water inlet head 207, and water enters the water pipe 206 and is transported to the water spray head 208, and the water is sprayed out through the water spray head 208, so that the product can be sprayed with water to cool it down, which is more functional.
