Description

Technical Field

[0001] This application relates to the field of vise structure equipment, and in particular to a fully automatic self-centering vise. Background Technology

[0002] As a common clamping tool in machining, the traditional vise consists of a fixed vise body, movable jaws, a lead screw, and a handle. The jaws are moved to clamp the workpiece by manually rotating the lead screw. This type of vise relies on manual operation, resulting in slow adjustment speed and low positioning accuracy. With the widespread use of CNC machine tools, semi-automatic improvement solutions have emerged, such as using electric or pneumatic drives to replace manual operation. In known technologies, electric vises drive the lead screw to rotate via a motor, but require an external power supply or controller, resulting in a complex structure and large space occupation. Pneumatic vises rely on compressed air systems, which suffer from high energy consumption and high noise levels. Furthermore, existing automated vises typically require additional sensors or positioning devices to achieve centering functions, leading to high costs and difficult maintenance.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0031] Specifically, such as Figure 1As shown in the embodiment of this application, a fully automatic self-centering vise is provided. The main body of the structure is provided with a housing 100. A moving groove 120 is provided on one side of the housing 100. In this embodiment of the application, the moving groove 120 is linearly arranged. A clamping device 200 is provided in the moving groove 120. The clamping device 200 moves in the moving groove 120 by a driving device 300. The movement of the clamping device 200 in the moving groove 120 facilitates the clamping of objects.

[0032] Specifically, in this embodiment, a receiving cavity 110 is provided inside the housing 100, and a moving groove 120 is connected to the receiving cavity 110. A driving device 300 and a transmission device 400 are provided inside the receiving cavity 110. The driving device 300 is connected to the clamping device 200 through the transmission device 400. In this application, the driving device 300 is a driving motor, which is a servo motor. The output end of the servo motor is connected to a driving gear 410, which is part of the transmission device 400. To facilitate the rotation of the driving gear 410, a mounting member 140 is provided in the receiving cavity 110 at the position corresponding to the servo motor. The mounting member 140 is set at the position corresponding to the servo motor to facilitate limiting the servo motor and avoid unstable installation caused by the operation of the servo motor.

[0033] The transmission device 400 is also provided with a driven gear 420 and a screw 430. The driven gear 420 is located on one side of the drive gear 410, and the driven gear 420 is meshed and rotatably connected with the drive gear 410, so that the drive gear 410 drives the driven gear 420 to rotate.

[0034] In the above, the radius and number of gears of the driving gear 410 are greater than the radius and number of gears of the driven gear 420, and the gear ratio of the driving gear 410 to the driven gear 420 is 2:1.

[0035] On the driven gear 420, the driven gear 420 and the screw 430 are coaxially connected, so that when the driven gear 420 rotates, the screw 430 rotates synchronously with the driven gear 420, that is, the angular velocity of the screw 430 and the driven gear 420 is the same.

[0036] A T-shaped clamp 210 is fitted onto the screw 430, and the T-shaped clamp 210 is threadedly connected to the screw 430.

[0037] In this embodiment, the T-shaped clamp 210 is part of the clamping device 200. The T-shaped clamp 210 moves linearly within the moving groove 120, and its movement is achieved by the rotation of the screw 430, specifically:

[0038] A thread is provided on the screw 430, and a fixing hole 212 is provided on the T-shaped clamp 210 corresponding to the position of the screw 430. The fixing hole 212 is threadedly connected to the screw 430. Since the T-shaped clamp 210 is limited by the moving groove 120, and the opening direction of the moving groove 120 in this application corresponds to the position of the screw 430, the T-shaped clamp 210 moves within the moving groove 120 when the screw 430 rotates.

[0039] In this embodiment, two T-shaped clamps 210 are provided, and both T-shaped clamps 210 are sleeved on the screw 430. In order to realize the clamp function, the two T-shaped clamps 210 need to move closer to each other and further away from each other. To achieve this effect, the threads in the fixing holes 212 on the two T-shaped clamps 210 are set as reverse threads. The reverse threads allow the two T-shaped clamps 210 to move closer to each other or further away from each other when the screw 430 rotates.

[0040] Preferably, in this embodiment of the application, the threads on the screw 430 corresponding to the positions of the two T-clamps 210 can be configured to be reverse threads, and the threads on the two T-clamps 210 can be threads in the same direction.

[0041] In the above, to ensure the normal operation of the screw 430, a fixing block 440 is also provided on the screw 430. Specifically, a limiting groove 150 is formed on the housing 100 at the position corresponding to the fixing block 440, and the fixing block 440 is located in the limiting groove 150. A limiting ring groove 431 is formed on the screw 430 at the position corresponding to the fixing block 440. The radius of the limiting ring groove 431 is smaller than the outer diameter of the screw 430, and the radius of the fixing block 440 corresponding to the limiting ring groove 431 is equal to the radius of the limiting ring groove 431. This allows the fixing block 440 to fix the screw 430 in position, making it convenient for the screw 430 to rotate only around the axis.

[0042] Meanwhile, to facilitate the stability of the screw 430 during rotation, a mounting base 130 is provided on the housing 100 at the position corresponding to the screw 430. The end of the mounting base 130 facing the screw 430 abuts against the screw 430, so that the screw 430 can be supported by the mounting base 130, which facilitates the stability of the screw 430.

[0043] In the above-mentioned embodiment, in order to facilitate the use of the T-shaped clamp 210, a fixing member 220 is provided at the end of the T-shaped clamp 210 away from the screw 430, and the fixing member 220 moves by the movement of the T-shaped clamp 210.

[0044] In this embodiment, the fixing member 220 is configured as a long strip structure. A jaw 222 is provided on the end of the fixing member 220 away from the T-shaped clamp 210. The two jaws 222 are arranged opposite to each other. The two jaws 222 move away from or closer to each other by the movement of the T-shaped clamp 210, so that the jaws 222 can easily clamp the object.

[0045] A first limiting part 211 is provided on one end of the T-shaped clamp 210 facing the fixing member 220, and a second limiting part 221 is provided on one end of the fixing member 220 facing the T-shaped member. The fixing member 220 is installed on the T-shaped clamp 210 through the connection of the first limiting part 211 and the second limiting part 221.

[0046] In the above, the first limiting part 211 is configured as a fixing groove, and the second limiting part 221 is configured as a positioning member. The cross-sectional shape of the positioning member corresponds to the cross-sectional shape of the fixing groove, so that the positioning member can be installed in the fixing groove.

[0047] Based on the above structure, this application provides a remote control circuit board and a battery in the accommodating cavity 110. The remote control circuit board is electrically connected to the drive device 300 to facilitate control of the drive device. At the same time, to facilitate signal control, the T-clamp 210 can be used as a control antenna to realize remote control. Furthermore, polyurethane glue is used to encapsulate the remote control circuit board in the housing to isolate it from cutting fluid and dust corrosion, thereby improving the durability of the equipment.

[0048] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
