Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a synchronous clamping device. Background Technology

[0002] Traditional rack machining methods mainly include milling, broaching, and grinding. While these processes can meet the machining requirements of single-tooth racks, they suffer from significant inefficiencies when processing racks with multiple teeth and multi-dimensional relationships. Especially in broaching, the high broaching force and speed present a significant challenge in achieving high-precision machining with multi-dimensional positioning, making it difficult to guarantee machining accuracy under real-time monitoring.

[0003] In industrial production, each process of material handling requires corresponding auxiliary processing equipment. Taking end processing of materials as an example, whether it's end cutting, accessory installation, or grinding, the material must first be fixed on a tooling fixture. Currently, tooling fixture systems mainly have two configurations: one is a fixed tooling fixture combined with a moving processing device, and the other is a fixed processing device combined with a moving tooling fixture. However, both methods have significant drawbacks when handling long-shaft materials. When using a moving tooling fixture, existing technology cannot provide effective support and fixation for the middle of the material, which not only affects processing stability but also makes it difficult to guarantee product accuracy. In addition, existing clamping devices often lack multi-dimensional adjustment capabilities, failing to meet the precise positioning requirements of complex workpieces, especially in situations where multiple clamping points need to be adjusted simultaneously, resulting in cumbersome operation and difficulty in guaranteeing positioning accuracy. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a synchronous clamping device that can achieve rack clamping and fixing as well as rack welding.

[0005] This utility model is implemented using the following method: a synchronous clamping device includes a support base, with first strip-shaped grooves at both the left and right ends of the upper surface of the support base, a dual-output motor disposed in the middle of the support base, the output ends of the dual-output motors being connected to a first screw, the first screw being disposed in the first strip-shaped groove, a first moving block being spirally sleeved on the first screw, a moving seat being disposed on the upper surface of the first moving block, a strip-shaped opening being opened on the side of the moving seat, and clamping members being sleeved at both the front and rear ends of the strip-shaped opening.

[0006] Furthermore, the clamping component includes a movable frame, which is fitted inside the strip-shaped opening. A first motor is disposed inside the strip-shaped opening, and the output end of the first motor is connected to a second screw. The movable frame is spirally fitted onto the second screw. Multiple balls are evenly spaced at both ends of the bottom surface inside the strip-shaped opening. The front half of the second screw has a left-hand thread, and the rear half of the second screw has a right-hand thread. A second strip-shaped groove is formed on the rear surface of the movable frame, and a second motor is disposed inside the second strip-shaped groove. The output end of the second motor is connected to a third screw. A U-shaped block is spirally fitted onto the third screw. Fixing blocks are bolted to both ends of the U-shaped block. A clamping plate is disposed at the end of the fixing block, and multiple toothed blocks are evenly spaced on the inner side of the clamping plate.

[0007] The beneficial effects of this utility model are as follows: This utility model uses a dual-output motor to drive the first screw, which in turn drives the moving seat to synchronously adjust the position of the clamping component. Combined with the multi-stage screw transmission structure inside the clamping component, it achieves multi-dimensional precise positioning and stable clamping. This has the advantages of improving processing stability and accuracy, and simplifying the operation process. It can achieve the clamping and fixing function of the rack, thereby enabling the rack to be welded and formed. It is used to achieve the positioning and clamping of the rack, thus facilitating the processing of the rack end. During the process, it effectively achieves feeding, end alignment, and precise positioning, providing reasonable conditions for improving the processing accuracy of the rack. This utility model has a simple structure, is easy to operate, and can effectively save manpower and material resources, and improve work efficiency. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] Please see Figures 1 to 3As shown, this utility model provides an embodiment: a synchronous clamping device, including a support base 1, with first strip-shaped grooves 2 at both the left and right ends of the upper surface of the support base 1, a dual-output motor 3 disposed in the middle of the support base 1, the output end of the dual-output motor 3 connected to a first screw 31, the first screw 31 disposed in the first strip-shaped groove 2, a first moving block 32 spirally sleeved on the first screw 31, a moving seat 33 disposed on the upper surface of the first moving block 32, a strip-shaped opening 34 opened on the side of the moving seat 33, and clamping members 4 sleeved at both the front and rear ends of the strip-shaped opening 34.

[0013] Among them, the dual-output motor refers to the drive device that can simultaneously output bidirectional rotational power. Specifically, it can be implemented by using a dual-axis stepper motor or an AC motor with a speed divider gearbox. Its function is to synchronously drive the screws on both sides to achieve symmetrical movement.

[0014] The first groove refers to the guide structure that extends along the length of the base. Specifically, it can be achieved by using a rectangular cross-section groove in conjunction with a wear-resistant liner to limit the running trajectory of the moving block.

[0015] The first screw refers to a transmission rod with a helical pattern, which can be implemented using a trapezoidal thread or a ball screw structure. It achieves linear displacement conversion through threaded engagement with the moving block.

[0016] The movable base refers to the support platform connected to the upper part of the movable block. Specifically, it can be realized by using an aluminum alloy profile welded frame structure, and the strip opening on its side provides installation space for the clamping components.

[0017] Specifically, after the dual-output motor starts, it drives the first screws on both sides to rotate synchronously, causing the first moving block to move towards or away from each other along the strip-shaped groove. As the moving block moves, it pushes the moving seat to move synchronously, allowing the clamping components installed on both sides of the moving seat to adjust their position according to the material length. The clamping components inside the strip-shaped opening can be finely adjusted along the length of the opening, forming a multi-level positioning adjustment mechanism. When the material is placed in the middle area of ​​the moving seat, the clamping components on both sides can move closer simultaneously to achieve end fixation, while the support structure in the middle of the base provides auxiliary support for the material.

[0018] Compared to existing technologies, traditional clamps can only achieve single-point clamping at the ends, while this solution achieves symmetrical linkage adjustment of the clamping components through a bidirectional screw drive system. Existing mobile clamps lack a central support structure; this device integrates a support module in the middle of the moving base, effectively preventing bending deformation of long-shaft materials during processing.

[0019] Through the above technical solution, this application can achieve synchronous positioning of the material's end and middle, ensuring the stability of long-shaft workpieces during moving processing. The bidirectional adjustment function of the clamping assembly adapts to the clamping requirements of objects of different sizes, eliminating the stress concentration problem caused by traditional single-point clamping. The support structure in the middle of the base forms a three-point positioning system, significantly improving processing accuracy and equipment operational reliability.

[0020] Please continue reading. Figures 1 to 3 As shown, in one embodiment of this utility model, the clamping member 4 includes a movable frame 41, which is sleeved within the strip-shaped opening 34. A first motor (not shown) is disposed within the strip-shaped opening 34, and the output end of the first motor is connected to a second screw 42. The movable frame 41 is spirally sleeved on the second screw 42. Multiple balls 43 are evenly spaced at both ends of the bottom surface of the strip-shaped opening 34. The front half of the second screw 42 has a left-hand thread, and the rear half has a right-hand thread. A second strip-shaped groove 44 is formed on the rear surface of the movable frame 41, and a second motor (not shown) is disposed within the second strip-shaped groove 44. The output end of the second motor is connected to a third screw 45, and a U-shaped block 46 is spirally sleeved on the third screw 45. Fixing blocks 47 are bolted to both ends of the U-shaped block 46, and a clamping plate 48 is disposed at the end of the fixing block 47. Multiple toothed blocks 49 are evenly spaced on the inner side of the clamping plate 48.

[0021] The movable frame refers to the sliding component used to support the clamping structure. Specifically, it can be implemented by combining a metal frame with a guide groove, and is used for horizontal displacement along the strip opening.

[0022] The second screw refers to a transmission component with bidirectional threads, which can be implemented using a segmented left-hand and right-hand thread structure to drive the moving frame to move synchronously in opposite directions.

[0023] A ball bearing is a rolling element embedded in the bottom surface of a strip-shaped opening. It can be made of stainless steel spheres and is used to reduce frictional resistance when the moving frame slides.

[0024] The U-shaped block refers to a U-shaped connector that mates with the third screw. Specifically, it can be achieved through a threaded connection and is used to adjust the vertical position of the clamping plate.

[0025] Toothed blocks refer to anti-slip structures attached to the inside of the clamping plate. They can be implemented using carbide toothed protrusions to enhance the friction when clamping materials.

[0026] Specifically, when the first motor drives the second screw to rotate, the left-hand and right-hand threaded sections respectively drive the two moving frames to move in opposite directions or back to back, and the ball bearings reduce the sliding resistance between the frames and the strip opening. The second motor drives the U-shaped block to rise and fall along the second strip groove through the third screw, thereby driving the clamping plate to adjust the vertical clamping height. The bolted fixing block allows for the replacement of clamping plates of different sizes, and the toothed block forms multi-point contact with the material surface to avoid displacement during processing.

[0027] Compared to existing technologies, most existing fixtures use a single-threaded screw to drive a single-sided clamping component, which cannot achieve bidirectional synchronous positioning and lacks vertical adjustment functionality. This solution achieves bidirectional synchronous movement through a double-threaded screw, reduces mechanical wear through ball bearings, and adapts to different processing height requirements through a height-adjustable clamping plate, thus solving the problem of unstable support in the middle of long-shaft materials.

[0028] Through the above technical solution, this application realizes bidirectional synchronous positioning and vertical position adjustment in the material clamping process, ensuring that long shaft materials obtain stable multi-point support during processing, avoiding processing errors caused by uneven clamping force, and can quickly adapt to the clamping requirements of materials of different sizes.

[0029] The dual-output motor and the motor in this utility model are both existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.

[0030] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
