Description

Technical Field

[0001] This utility model relates to the field of transmission shaft workpiece processing technology, and in particular to a feeding device for processing automotive transmission shafts. Background Technology

[0002] A driveshaft is a circular component that connects or assembles various parts, and can move or rotate. It is generally made of lightweight alloy steel tubing with good torsional resistance. In front-engine, rear-wheel-drive vehicles, it transmits the rotation of the transmission to the final drive shaft, and it can consist of several sections connected by universal joints. It is a high-speed, low-support rotating body.

[0003] As a critical component in automobiles, the driveshaft requires multiple processing steps, necessitating repeated material feeding and transport. Existing feeding methods often employ a device like the one disclosed in CN214610218U, which uses a rotating block in the unloading device to evenly and orderly arrange the driveshafts on a conveyor belt. Then, a cylinder in the pushing device pushes the driveshafts into a fixture. The clamping device uses a rotating shaft and connecting rod to adjust the angle and control the fixture to fix driveshafts of different specifications. However, the driveshaft feeding must meet the needs of both upstream and downstream processing. Otherwise, it easily leads to an accumulation of semi-finished or finished driveshafts on the production line. In particular, errors in the quantity fed each time are prone to occur, affecting the orderly transport of driveshafts on the production line, preventing them from moving along the predetermined path, and even causing blockages in the feeding line due to imbalance. This can also easily disrupt subsequent processing steps. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding device for processing automotive drive shafts includes a machine base. The upper right side of the machine base is integrally connected to a feeding box for placing at least two drive shaft workpieces, and the feeding box is provided with a support mechanism for moving the drive shaft workpieces. The lower end of the machine base is integrally connected to a load-bearing bracket, on which a drive motor is fixedly installed, and the load-bearing bracket is provided with a feeding mechanism driven by the drive motor for stepping horizontally pushing the drive shaft workpieces from right to left.

[0007] Preferably, the machine base has a long frame structure, and guide grooves for the workpiece ends of the sliding sleeve transmission shaft are provided on both sides of the machine base.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A feeding device for processing automotive drive shafts includes a machine base 1. The upper right side of the machine base 1 is integrally connected to a feeding box 2 for placing at least two drive shaft workpieces. It should be noted that by preparing materials on the right side of the machine base 1, i.e. preparing multiple drive shaft workpieces, and then feeding them in two steps, it is possible to sequentially provide one drive shaft workpiece for the processing of the drive shaft.

[0024] The feed box 2 is equipped with a support mechanism 4 for the workpiece of the movable drive shaft, as detailed in the instruction manual appendix. Figure 3 With appendix Figure 4 The support mechanism 4 includes a receiving elongated hole 42 and a receiving cavity 43 opened in the side wall of the feeding box 2. An L-shaped baffle 44 is rotatably installed in the receiving elongated hole 42, and an elastic support member 45 for movably supporting the L-shaped baffle 44 is movably arranged in the receiving cavity 43. It should be noted that under the elastic support of the elastic support member 45, the L-shaped baffle 44 tends to deflect horizontally to provide support for the drive shaft workpiece built into the feeding box 2. At the same time, when a drive shaft workpiece at the bottom of the feeding box 2 moves to the machine base 1, the L-shaped baffle 44 lacks support and thus tends to deflect vertically to facilitate the automatic downward movement of the drive shaft workpiece. A light sensor and controller for controlling the deflection of the L-shaped baffle 44 can be set on the feeding box 2 to improve the sensitivity of controlling the movement of the drive shaft workpiece onto the machine base 1.

[0025] The lower end of the machine base 1 is integrally connected to a load-bearing bracket 3 to facilitate the high-level erection of the machine base 1.

[0026] A drive motor 5 is fixedly mounted on the load-bearing bracket 3, and a feeding mechanism 6 driven by the drive motor 5 is provided on the load-bearing bracket 3 for stepping horizontally pushing the workpiece of the transmission shaft from right to left. See the attached instruction manual for details. Figure 5 The feeding mechanism 6 includes a drive shaft 61 rotatably mounted on the right side of the load-bearing bracket 3 and fixedly connected to the output end of the drive motor 5. A limit rod 62 is fixedly mounted on the left side of the load-bearing bracket 3. An eccentric tie rod 63 is fixedly connected to the drive shaft 61. The drive motor 5 drives the drive shaft 61 to rotate, causing the U-shaped rod 65 to have a horizontal position difference. A limit rod 64 is rotatably connected to the limit rod 62. The U-shaped rod 65 is pin-connected between the eccentric tie rod 63 and the limit rod 64. At the same time, due to the traction and limiting effect of the limit rod 64, the U-shaped rod 65 can only move horizontally and vertically to a certain extent. Guides are symmetrically provided on the left and right sides of the load-bearing bracket 3. The guide holes 66 are both slidably fitted with lifting sliders 67, and a reciprocating rod 68, which is movably pulled by a mountain-shaped rod 65, is slidably fitted between the two lifting sliders 67. The guide holes 66 are vertically opened, and the reciprocating rod 68 can slide left and right along the lifting sliders 67. Multiple fish-scale push rods 69 are integrally connected to the reciprocating rod 68. The fish-scale push rods 69 are arranged in a fish-scale-like manner so that when moving, each fish-scale push rod 69 acts on only a single drive shaft workpiece. During the oblique lifting and lowering movement of the fish-scale push rods 69 with the reciprocating rod 68, the drive shaft workpiece located on the right side of the machine base 1 is pushed step by step to the left side of the machine base 1.

[0027] The machine base 1 has a long frame structure, and guide grooves for the ends of the sliding sleeve transmission shaft workpiece are opened on both sides of the machine base 1 to guide and limit the horizontally moving transmission shaft workpiece, so that the transmission shaft workpiece can only move in a straight line along the machine base 1.

[0028] The lower left side of the feed box 2 has a notch 41 that allows only one drive shaft workpiece to pass through at a time, so that only one drive shaft workpiece can pass through the feed box 2 at a time.

[0029] A traction rod 46 is connected to the elastic support 45 and the L-shaped baffle 44 by a pin. The extension and retraction of the elastic support 45 is used to adjust the deflection of the L-shaped baffle 44, so as to control the downward movement of the workpiece in the feed box 2.

[0030] The middle end of the mountain-shaped rod 65 is connected to the reciprocating rod 68 by a pin. Under the traction of the mountain-shaped rod 65, the reciprocating rod 68 moves in an inclined manner in the guide hole 66 and the lifting slider 67.

[0031] It should be noted that the specific model and specifications of the drive motor 5 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0032] The functional principle of this utility model can be explained through the following operation methods:

[0033] At least two drive shaft workpieces are placed in the feed box 2. Because of the notch 41, one drive shaft workpiece moves to the machine base 1, and the other drive shaft workpiece is located on the two L-shaped baffles 44. When it loses the support of the drive shaft workpiece below, the L-shaped baffle 44 applies pressure to the elastic support member 45 through the traction link 46, so that the L-shaped baffle 44 deflects and the drive shaft workpiece moves onto the machine base 1.

[0034] The drive motor 5 controls the drive shaft 61 to rotate. The drive shaft 61 pulls the mountain-shaped rod 65 through the eccentric tie rod 63. At the same time, due to the limiting effect of the limit rod 62 and the limit tie rod 64 on the mountain-shaped rod 65, the mountain-shaped rod 65 can only perform periodic lifting and lowering movements.

[0035] Meanwhile, due to the guiding and limiting effect of the guide hole 66 and the lifting slider 67, the fish scale push rod 69 pushes the transmission shaft workpiece on the machine platform 1 to move to the left in sequence.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
