Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, and in particular to a workpiece clamping device for CNC lathes. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting internal and external cylindrical surfaces, internal and external conical surfaces with arbitrary cone angles, complex rotating internal and external curved surfaces, and cylindrical and conical threads on shaft or disc-shaped parts. They can also perform grooving, drilling, reaming, boring, and other operations. During the machining process on a CNC lathe, clamping devices are needed to fix the workpiece in place to ensure machining accuracy and stability.

[0003] Existing workpiece clamping devices for CNC lathes have some shortcomings in use. On the one hand, the clamping seats of many clamping devices are fixed and cannot be quickly changed according to workpieces of different sizes and shapes, resulting in poor versatility and inflexibility in use;

[0004] On the other hand, when clamping a workpiece, it is difficult to accurately control the clamping force. If the clamping is too loose, the workpiece may shift during the machining process, affecting the machining accuracy. If the clamping is too tight, the workpiece may be damaged, resulting in production losses. Therefore, we propose a CNC lathe workpiece clamping device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a workpiece clamping device for CNC lathes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A CNC lathe workpiece clamping device includes a control box, a clamping platform is fixedly installed on the top of the control box, a plurality of drive slots are opened on the top of the clamping platform, a drive seat is slidably installed in the drive slots, and a clamping seat for workpiece clamping is installed on one side of the drive seat through a detachable mechanism.

[0008] The bottom of the clamping table is provided with multiple moving slots. A moving seat is fixedly installed on one side of the drive seat and extends into the corresponding moving slot. A hydraulic cylinder is installed at the bottom of the clamping table, and a drive mechanism is provided between the hydraulic cylinder and the multiple moving seats.

[0009] Preferably, the driving mechanism includes an extrusion plate and hinge rods. The extrusion plate is fixedly mounted on the output shaft of the hydraulic cylinder. Multiple hinge rods are hinged to the top of the extrusion plate, and the top ends of the hinge rods are hinged to corresponding movable seats.

[0010] Preferably, the bottom of the clamping table is provided with an installation groove, and the hydraulic cylinder is fixedly installed in the installation groove.

[0011] Preferably, a plurality of guide rods are installed on the bottom inner wall of the control box, and the top ends of the guide rods are fixedly installed on the clamping table, with the extrusion plate slidably sleeved on the guide rods.

[0012] Preferably, the top of the clamping seat is provided with a T-shaped guide groove with one side open, and multiple T-shaped guide seats are fixedly installed on the top of the clamping table, and the T-shaped guide groove and the T-shaped guide seats are slidably connected.

[0013] Preferably, the disassembly mechanism includes a bolt groove, a threaded hole, and a fixing bolt. The clamping seat has a bolt groove, the drive seat has a threaded hole, and a fixing bolt that matches the bolt groove is installed in the threaded hole.

[0014] Preferably, each of the two opposing clamping seats has a groove on one side, and a pressure sensor is installed in the groove.

[0015] Preferably, a controller is installed on one side of the control box, and the solenoid valve and pressure sensor on the hydraulic cylinder are electrically connected to the controller.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting a detachable mechanism, the clamping seat can be easily and quickly removed from the drive seat, making it convenient to change the appropriate clamping seat according to the workpiece of different size and shape, improving the versatility and flexibility of the device, and meeting different processing needs;

[0018] 2. Utilizing a drive mechanism, under the action of a hydraulic cylinder, the moving seat is driven to move through the extrusion plate and hinge rod, thereby enabling the drive seat and clamping seat to move synchronously, achieving the clamping or releasing of the workpiece. The drive structure is simple, easy to operate, and runs stably, improving work efficiency.

[0019] 3. The pressure sensor can detect the clamping force of the clamping seat on the workpiece in real time and transmit the detection signal to the controller. The controller controls the operation of the hydraulic cylinder according to the preset pressure value, thereby accurately controlling the clamping force, avoiding processing problems caused by clamping too loosely or too tightly, ensuring processing accuracy, and protecting the workpiece from damage.

[0020] 4. The sliding connection between the T-shaped guide groove and the T-shaped guide seat guides the movement of the clamping seat, ensuring the stability and accuracy of the clamping seat movement and further improving the clamping precision. Attached Figure Description

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a workpiece clamping device for a CNC lathe.

[0028] Reference Figure 1-4 A CNC lathe workpiece clamping device includes a control box 101. A clamping platform 102 is fixedly installed on the top of the control box 101. The top of the clamping platform 102 has multiple drive slots 103. A drive seat 104 is slidably installed in the drive slots 103. A clamping seat 105 for workpiece clamping is installed on one side of the drive seat 104 through a detachable mechanism. The bottom of the clamping platform 102 has multiple moving slots 401. A moving seat 402 is fixedly installed on one side of the drive seat 104 and extends into the corresponding moving slot 401. A hydraulic cylinder 502 is installed at the bottom of the clamping platform 102, and a drive mechanism is provided between the hydraulic cylinder 502 and the multiple moving seats 402.

[0029] In this embodiment, the driving mechanism includes an extrusion plate 404 and hinge rods 405. The extrusion plate 404 is fixedly mounted on the output shaft of the hydraulic cylinder 502. Multiple hinge rods 405 are hinged to the top of the extrusion plate 404, and the top ends of the hinge rods 405 are hinged to the corresponding moving seats 402. The bottom of the clamping table 102 is provided with an installation groove 501, and the hydraulic cylinder 502 is fixedly mounted in the installation groove 501. By providing hinge rods 405, the movement of the extrusion plate 404 can drive multiple moving seats 402 to move synchronously through the hinge rods 405.

[0030] In this embodiment, a plurality of guide rods 403 are installed on the bottom inner wall of the control box 101, and the top end of the guide rod 403 is fixedly installed on the clamping table 102. The extrusion plate 404 is slidably sleeved on the guide rod 403. By providing the guide rod 403, the extrusion plate 404 can be guided in the vertical direction, so that the extrusion plate 404 can move in the vertical direction.

[0031] In this embodiment, the top of the clamping seat 105 is provided with a T-shaped guide groove 201 with one side open, and a plurality of T-shaped guide seats 202 are fixedly installed on the top of the clamping table 102. The T-shaped guide groove 201 and the T-shaped guide seats 202 are slidably connected. By providing the T-shaped guide groove 201 and the T-shaped guide seats 202, the clamping seat 105 can be moved stably.

[0032] In this embodiment, the disassembly mechanism includes a bolt groove 301, a threaded hole 302, and a fixing bolt 303. The clamping seat 105 is provided with a bolt groove 301, and the drive seat 104 is provided with a threaded hole 302. A fixing bolt 303 that matches the bolt groove 301 is installed in the threaded hole 302. By providing the fixing bolt 303 and the bolt groove 301, the clamping seat 105 can be disassembled and assembled.

[0033] In this embodiment, a groove is provided on one side of each of the two opposing clamping seats 105, and a pressure sensor is installed in the groove. By providing the groove and the pressure sensor, the clamping force of the clamping seat 105 can be detected.

[0034] In this embodiment, a controller is installed on one side of the control box 101, and the solenoid valve and pressure sensor on the hydraulic cylinder 502 are electrically connected to the controller. By setting the controller, the pressure of the clamping seat 105 can be detected.

[0035] In this invention, during use, a suitable clamping seat 105 is selected according to the size and shape of the workpiece. The clamping seat 105 is installed on the drive seat 104 through a detachable mechanism. The workpiece is placed on the clamping table 102, located between two opposing clamping seats 105. The controller is activated, and the controller controls the hydraulic cylinder 502 to work. The output shaft of the hydraulic cylinder 502 extends and drives the extrusion plate 404 to move upward. The extrusion plate 404 slides on the guide rod 403, and at the same time drives the hinge rod 405 to rotate. The rotation of the hinge rod 405 pushes the moving seat 402 to slide in the moving groove 401. The moving seat 402 drives the drive seat 104 to slide in the drive groove 103. The drive seat 104 drives the clamping seat 105 to move. The T-shaped guide groove 201 on the clamping seat 105 slides on the T-shaped guide seat 202, so that the clamping seat 105 moves smoothly and clamps the workpiece.

[0036] During the clamping process, the pressure sensor detects the clamping force in real time and transmits the signal to the controller. When the clamping force reaches the preset value, the controller controls the hydraulic cylinder 502 to stop working, thus completing the clamping of the workpiece.

[0037] After processing is completed, the controller controls the output shaft of the hydraulic cylinder 502 to retract, which drives the extrusion plate 404 to move downward. The hinge rod 405 pulls the moving seat 402 to move in the opposite direction, thereby causing the clamping seat 105 to release the workpiece and remove it.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
