Description

Technical Field

[0001] The utility model relates to the technical field of shaft part processing, in particular to a shaft processing quick clamping die. Background Art

[0002] Shafts are a common component found in hardware accessories, primarily used to support transmission components, transmit torque, and withstand loads. They are typically rotating parts with a length greater than their diameter, consisting of a concentric shaft with an outer cylindrical surface, a conical surface, an inner bore, threads, and corresponding end faces. Shafts can be categorized into various types based on their structural shape, including smooth shafts, stepped shafts, special-shaped shafts, solid shafts, hollow shafts, and crankshafts.

[0003] Existing shaft processing clamping dies generally rely on manually rotating bolts to actuate the clamping blocks, a process that is not only cumbersome but also labor-intensive. Furthermore, these dies are often designed to be non-detachable, limiting their compatibility with shafts of varying diameters. Furthermore, these dies lack the ability to adjust to shafts of varying lengths, resulting in poor adaptability. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a quick clamping die for machining shafts.

[0009] As a further improvement of the present invention, an arc-shaped groove is formed at one end of the clamping block away from the hydraulic cylinder, and an arc-shaped block is fixedly connected in the arc-shaped groove.

[0010] As a further improvement of the present invention, the size of the plug-in column matches the size of the plug-in slot, and the plug-in column is made of stainless steel.

[0011] As a further improvement of the present invention, the size of the two hole slot blocks matches the size of the screw slot to prevent the two hole slot blocks from rotating together when the double-threaded rod rotates.

[0012] Beneficial effects of the utility model:

[0013] By installing a hydraulic cylinder and clamping blocks, and using a motor to drive the double-threaded rod, the two slot blocks move along the axis of the screw slot through the principle of thread transmission.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Figs. 1-2 A quick clamping mold for shaft processing includes a base 1, a screw groove 2 is opened at the upper end of the base 1, a double-threaded rod 3 is provided in the screw groove 2, and the two ends of the double-threaded rod 3 are respectively connected to the inner side walls of the screw groove 2 through bearings to ensure the stability of rotation. A motor 4 is installed on one side of the base 1, and the output shaft end of the motor 4 passes through the screw groove 2 and is connected to the double-threaded rod 3 to realize power transmission. Two hole slot blocks 10 are respectively threadedly sleeved on the two ends of the double-threaded rod 3, and the inner walls of the two hole slot blocks 10 are provided with threads matching the threads of the double-threaded rod 3. The threaded holes ensure that the hole slot block 10 can move along the axis of the double-threaded rod 3. The two hole slot blocks 10 slide in the screw groove 2, and their outer side walls are tightly fitted with the inner side walls of the screw groove 2 to limit the rotation of the hole slot block 10. The size of the two hole slot blocks 10 matches the size of the screw groove 2, further preventing the rotation of the double-threaded rod 3 from driving the two hole slot blocks 10 together. The upper ends of the two hole slot blocks 10 are respectively fixedly connected to the movable plate 5 by welding. The upper ends of the two movable plates 5 are fixedly connected to two fixed plates 6 by bolts for easy disassembly and maintenance. A clamping mechanism is provided between each two fixed plates 6 for clamping and fixing shaft parts.

[0021] The clamping mechanism includes a hydraulic cylinder 7 installed on one side of the fixed plate 6. The hydraulic cylinder 7 is fixed to the fixed plate 6 by bolts. The telescopic end of the hydraulic cylinder 7 passes through the fixed plate 6 and is fixedly connected to the fixed block 8 to realize direct transmission of power. A fixed groove 17 is provided on one side of the fixed block 8. A clamping block 9 is slidably installed in the fixed groove 17. An arc groove is provided on the end of the clamping block 9 away from the hydraulic cylinder 7. The shape of the arc groove matches the contour of the shaft parts to improve the stability of the clamping. An arc groove is fixedly connected to the arc groove. The shaped block 16 and the arc block 16 are made of wear-resistant material to increase the friction and durability of the clamping. A plug-in slot 11 is provided at the upper end of the clamping block 9. A plug-in column 12 that matches the size of the plug-in slot 11 is inserted into the plug-in slot 11. The plug-in column 12 is made of stainless steel. The end of the plug-in column 12 away from the plug-in slot 11 passes through the fixed groove 17 and extends outward. The extended part is used to connect with the connecting plate 14. The upper end of the connecting plate 14 is fixedly connected with a pull ring 15 by welding. The pull ring 15 is convenient for the operator to pull.

[0022] When the present invention is used, the worker first inserts the clamping block 9 suitable for the shaft parts into the fixing groove 17 of each fixing block 8, and drives the plug-in column 12 out of the fixing groove 17 by pulling the pull ring 15. At this time, there is no obstruction in the fixing groove 17, and the clamping block 9 can be inserted into it. Then the plug-in pull ring 15 is released, and the plug-in column 12 will be inserted into the plug-in groove 11 under the action of the spring 13, completing the fixation of each clamping block 9. Then the motor 4 is started to drive the double-headed threaded rod 3 to rotate. The rotation of the double-headed threaded rod 3 will drive the two hole slot blocks 10 to move closer or farther away from each other, thereby adapting to the length of the shaft parts. After the adjustment is completed, the two ends of the shaft parts are placed between the two clamping blocks 9 respectively, and multiple hydraulic cylinders 7 are driven at the same time to drive multiple clamping blocks 9 to move closer to each other to complete the clamping of the shaft parts.
