Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, and more specifically, to a clamping and connecting mechanism for a gear hobbing machine. Background Technology

[0002] The clamping mechanism of a gear shaper is a crucial component, ensuring workpiece stability and machining accuracy during gear processing. During operation, the gear shaper cutter reciprocates, rolling relative to the workpiece, which rotates on the worktable. With technological advancements, the clamping mechanism of gear shapers is constantly being optimized and innovated. Traditional clamping mechanisms can be complex, inefficient, and lack versatility. These mechanisms often require manual operation, which is time-consuming and labor-intensive, and difficult to adapt to workpieces of different sizes and shapes. With the application of CNC technology, modern gear shaper clamping mechanisms are trending towards automation and intelligence. Computer control enables precise control of clamping force and automation of the clamping process, thereby improving processing efficiency and accuracy.

[0003] For example, the patent with publication number CN211939364U proposes a rotary table for a CNC gear shaping machine. By incorporating a main clamping plate, a secondary clamping plate, and a second cylinder, it can accommodate gears of different bore diameters, improving the applicability of this invention. Existing gear shaping machine table clamping mechanisms primarily focus on the degree of workpiece clamping and ease of operation. However, the gear shaping machine table needs to rotate during operation to process teeth at different positions. Because the gear shaping cutter generates strong axial and longitudinal forces on the workpiece and the workpiece clamping mechanism during operation, the clamping connection mechanism is prone to misalignment with the transmission mechanism of the table rotation mechanism. This can easily lead to malfunctions in the clamping mechanism during machine rotation, resulting in incomplete rotation or loosening of the workpiece, causing damage to both the workpiece and the gear shaping cutter. Utility Model Content

[0005] The embodiments of this utility model are achieved through the following technical solutions:

[0006] A gear hobbing machine clamping connection mechanism includes a connecting mechanism for connecting a rotating mechanism and a clamping mechanism for clamping a workpiece. The connecting mechanism is further provided with a center for axially supporting and fixing the connecting mechanism and driving it to rotate. The center is provided with a fixing member for radially fixing the connecting mechanism and the clamping mechanism.

[0007] Preferably, the clamping mechanism includes a clamping member for radially telescopically fixing the workpiece, the clamping member including an inner side for inwardly clamping and fixing the workpiece and an outer side for outwardly tensioning and fixing the workpiece.

[0008] Preferably, the clamping mechanism further includes a support member for supporting and fixing the workpiece, the support member being connected to the connecting mechanism via a connector.

[0009] Preferably, the connecting mechanism further includes a connecting plate for increasing its contact area with the clamping mechanism, the connecting plate being connected to the support member, and the clamping member having a limiting block for being limited by the connecting plate.

[0010] Preferably, the connecting mechanism includes a socket for connecting the tip and a connecting post for connecting the socket to the connecting plate.

[0011] Preferably, the fixing member is configured as a connecting sleeve covering the connecting mechanism, with one end of the fixing member connected to the center and the other end connected to the clamping mechanism.

[0012] Preferably, the fixing member is provided with a threaded tube for installation and radial fixation, the clamping mechanism is provided with a threaded hole, and the threaded tube and the threaded hole are connected by a screw.

[0013] Preferably, the fastener further includes a threaded sleeve for connecting the tip, the tip having threads for connecting the threaded sleeve.

[0014] By adopting the above technical solutions and designing the connecting and clamping mechanisms, rapid connection and clamping can be achieved, thereby improving work efficiency. The center not only axially supports and fixes the connecting mechanism but also drives its rotation, providing stable support and precise positioning. The clamping element in the clamping mechanism has inner and outer surfaces, allowing for inward or outward clamping of workpieces, suitable for workpieces of different shapes and sizes. The design of the support element and connecting plate increases the contact area between the connecting and clamping mechanisms, improving clamping stability and accuracy. The fixing element is designed as a connecting sleeve covering the connecting mechanism, connecting the center at one end and the clamping mechanism at the other, facilitating radial fixing of the connecting structure, preventing misalignment during rotation, and making the overall structure compact, easy to install and maintain. The threaded tube on the fixing element connects to the threaded hole on the clamping mechanism via a screw, allowing for easy adjustment and fixing of the clamping force. The fixing element also includes a threaded sleeve, connected to the thread on the center, enhancing the strength and reliability of the radial connection.
