Abstract

This application discloses an intermediate shaft clamping and feeding device, including a placement groove and a frame. The placement groove is disposed on the frame and is a V-shaped groove with a preset groove angle and depth. A guide wheel assembly is disposed inside or at the bottom of the V-shaped placement groove, including at least one freely rotatable or power-driven guide wheel. The rim of the guide wheel contacts the outer peripheral surface of the shaft. The guide wheel is mounted on a guide wheel bracket via bearings, and the surface of the guide wheel is covered with an anti-slip and wear-resistant material. A bar stock clamping assembly is disposed on one side of the V-shaped placement groove for clamping and positioning the shaft within the V-shaped groove.

Description

Technical Field

[0001] This application relates to the field of bar stock processing technology, specifically to an intermediate shaft clamping and feeding device. Background Technology

[0002] Traditional shaft clamping devices typically employ planar structures or simple circular slots, which present limitations in shaft positioning and clamping. For example, when using a planar slot clamping system, the positioning accuracy of the shaft is often affected by the operator, and the shaft is prone to shifting during placement, resulting in poor clamping accuracy. Furthermore, during machining and feeding, existing technologies mostly rely on manual or semi-automatic clamping force adjustments. This method is complex and inefficient, failing to meet the high-precision and efficiency requirements of high-speed production lines. Summary of the Invention

[0004] To achieve the above objectives, this application provides the following technical solution: an intermediate shaft clamping and feeding device, comprising a placement groove and a frame, wherein the placement groove is disposed on the frame and the placement groove is a V-shaped groove having a preset groove opening angle and groove depth;

[0005] The guide wheel assembly is located inside or at the bottom of the V-shaped placement groove, including at least one guide wheel that can rotate freely or be driven by power. The rim of the guide wheel contacts the outer peripheral surface of the shaft. The guide wheel is mounted on the guide wheel bracket by bearings. The surface of the guide wheel is covered with anti-slip and wear-resistant material.

[0006] The bar stock clamping assembly is located on one side of the V-shaped placement groove and is used to clamp and position the shaft in the V-shaped groove. The bar stock clamping assembly includes a mounting side frame, which is fixedly connected to one side of the frame.

[0007] The clamping member is rotatably mounted on the mounting side frame via a hinge shaft, and the free end of the clamping member is provided with a V-groove clamping surface that matches the outer circle of the shaft.

[0008] The cylinder body of the adjusting cylinder is hinged to the frame, and the end of its telescopic rod is hinged to the middle or the other end of the clamping member, which is used to drive the clamping member to swing around the hinge point to achieve clamping and releasing of the shaft.

[0009] As a preferred technical solution of this application, the pressing surface of the clamping member is lined with an elastic buffer layer to avoid damaging the surface of the shaft.

[0010] As a preferred technical solution of this application, the guide wheel assembly is formed by multiple guide wheel transmission components spaced apart along the feeding direction of the shaft component, thus forming a continuous support track.

[0011] As a preferred technical solution of this application, the guide wheel transmission component at the front end is connected to the bearing seat set on the frame through a connecting shaft, and the synchronous wheel sleeved at the end of the connecting shaft is connected to the output end of the drive motor through a synchronous belt, thus forming an active feeding mechanism.

[0012] As a preferred technical solution of this application, the opening direction of the V-shaped placement groove is upward, and the two inclined surfaces are symmetrically arranged about the vertical center plane to ensure that the shaft is positioned in the center.

[0013] As a preferred technical solution of this application, the guide wheel bracket is composed of two lateral support plates, each lateral support plate including a vertical section and an inclined end, and a guide wheel assembly is installed on the vertical section of the lateral support plate.

[0014] As a preferred technical solution of this application, the clamping member includes a main support frame, a lower pressure block and a locking plate. The lower pressure block is correspondingly arranged in a rectangular groove on the main support frame, and a locking plate is arranged in a through hole on the lower pressure block to restrict the lower pressure block.

[0015] As a preferred technical solution of this application, the surface of the guide wheel in the guide wheel transmission component is covered with an anti-slip and wear-resistant material.

[0016] Compared with the prior art, the beneficial effects of this application are: the V-shaped placement groove design of this application enables the shaft to be automatically centered and positioned under gravity, ensuring the precise position of the shaft during clamping. Through automatic positioning, the shaft offset situation in traditional planar groove structures is avoided, greatly improving clamping accuracy;

[0017] Through the continuous support and friction of the guide roller assembly, the shaft remains stable throughout the feeding process. The use of a drive motor ensures efficient and smooth automatic propulsion of the shaft, reducing manual operation and equipment wear, and improving production efficiency.

[0018] By using a cylinder-driven clamping mechanism, the shaft can be quickly clamped and released. The automated operation greatly reduces the reliance on manual operation, speeds up the response of clamping actions, and allows for rapid adjustment of clamping force according to production needs, enabling more flexible clamping operations and greatly improving the efficiency and production capacity of the production line.

[0024] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0025] Please see Figure 1-4 This application provides a technical solution: an intermediate shaft clamping and feeding device, including a placement groove 1 and a frame 2, wherein the placement groove 1 is disposed on the frame 2, and its cross-section is a V-shaped structure with a preset groove angle and groove depth, the opening direction is upward, and the two inclined surfaces are symmetrically arranged about the vertical center plane. The groove angle is set according to the outer diameter of the shaft and the clamping stability requirements, preferably 90°. The inclined groove surface of the V-shaped placement groove 1 is provided with a wear-resistant lining. This structure helps the shaft to be automatically centered and positioned under gravity, improving the clamping accuracy.

[0026] A guide wheel assembly 3 is provided at the bottom of the placement groove 1. The guide wheel assembly 3 includes multiple guide wheel transmission components arranged at intervals along the feeding direction of the shaft to form a continuous support track. The guide wheel transmission component includes at least one guide wheel that can rotate freely or be driven by power. The rim of the guide wheel contacts the outer peripheral surface of the shaft to provide rolling support during the feeding process of the shaft and reduce frictional resistance. The guide wheel bracket 4 consists of two lateral support plates. The lateral support plates include a vertical section and an inclined end. The guide wheel is installed on the vertical section to ensure stable contact with the outer circular surface of the shaft.

[0027] The guide wheel surface is covered with anti-slip and wear-resistant material, such as polyurethane or nitrile rubber, and has a micro-convex textured structure to enhance friction and prevent the shaft from slipping.

[0028] A drive motor 8 is provided at the end of the guide wheel assembly 3 to drive the guide wheel transmission component to rotate, forming an active feeding mechanism to realize the automatic propulsion of the shaft component.

[0029] The bar stock clamping assembly is located on one side of the V-shaped placement groove 1 to clamp and position the shaft within the V-shaped groove, preventing it from jumping or shifting during feeding or processing. It includes a mounting side frame 5 and a clamping component 6. The mounting side frame 5 is fixedly connected to one side of the frame 2 and extends perpendicular to the shaft feeding direction.

[0030] The clamping component 6 is rotatably mounted on the mounting side frame 5 via a hinge shaft. Its free end is provided with an arc-shaped clamping surface that matches the outer circle of the shaft. To avoid damaging the surface of the shaft, the arc-shaped clamping surface is lined with an elastic buffer layer, such as a silicone or rubber pad, which has a certain degree of flexibility and buffering performance.

[0031] More specifically, the clamping member 6 includes a main support frame 61, a lower pressure block 62 and a locking plate 63. The lower pressure block 62 is correspondingly arranged in a rectangular groove on the main support frame 61, and the locking plate 63 is arranged in a through hole on the lower pressure block 62 to restrict the lower pressure block 62.

[0032] The cylinder body of the adjusting cylinder 7 is hinged to the frame 2, and the end of its telescopic rod is hinged to the middle or the other end of the clamping member 6. Driven by the adjusting cylinder 7, the clamping member 6 can swing around the hinge point to realize the clamping and releasing operation of the shaft. This structure can quickly complete the clamping action and is suitable for automated production lines.

[0033] In use, the shaft to be processed is placed in the V-shaped placement groove 1, and the shaft is automatically centered and positioned under gravity. At this time, the drive motor 8 starts, driving the guide wheel assembly 3 to rotate. The shaft moves along the feeding direction under the support of the guide wheels and the action of friction. After running to the set position, the adjusting cylinder 7 starts, driving the clamping part 6 to swing towards the shaft. The arc-shaped clamping surface fits against the outer circle of the shaft, realizing clamping and positioning. The whole process runs smoothly, the positioning is reliable, and it is suitable for clamping and conveying shafts of various specifications.

[0034] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
