Description

Technical Field

[0001] This utility model specifically relates to a rotary spindle transmission device for a grinding machine. Background Technology

[0002] When machining shaft-type workpieces, especially long shaft-type workpieces, using a grinding machine, the headstock spindle and tailstock centers of the grinding machine are inserted into the center holes at both ends of the workpiece to provide positioning and support. When the workpiece is rotated, directly letting the centers rotate with the workpiece is not enough friction. Usually, a chuck is required. Then, when the grinding machine spindle rotates, the lever will hook or push the bent tail of the chuck, thereby transmitting the rotational force to the chuck. The chuck then transmits this rotational force to the workpiece it clamps, causing the workpiece to rotate between the two centers.

[0003] Existing methods for clamping and fixing shaft-type workpieces using a chuck require manual clamping when changing to different shaft-type workpieces, which is laborious, time-consuming, and inefficient. Some methods use a power chuck to clamp the workpiece, but this requires changing the center structure of the grinding machine headstock, which is also laborious and may affect the grinding machine's accuracy, resulting in poor performance. Therefore, we propose a grinding machine rotary spindle drive device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution: a rotary spindle transmission device for a grinding machine, comprising:

[0023] Driven plate 3, with an elastic guide component 2 provided on one side;

[0024] Mounting plate 1 is disposed at one end of the elastic guide component 2, and mounting holes 8 are provided on the inner side of the mounting plate 1 along the circumferential direction for connecting with the grinding machine.

[0025] Both the mounting plate 1 and the driven plate 3 are annular, which facilitates the tip of the grinding machine spindle to extend into the annular space and engage with one end of the workpiece shaft 6. At the same time, the tailstock of the grinding machine moves by hydraulic drive, and the tip of the tailstock engages with the other end of the workpiece shaft 6 to press the workpiece shaft 6 tightly. The mounting plate 1 is fixed to the support end face of the shoulder of the CNC grinding machine's rotary axis so that the grinding machine can drive the mounting plate 1 to rotate, thereby driving the workpiece shaft 6 to rotate through the driven plate 3 and the anti-rotation pin 4 for grinding.

[0026] The anti-rotation pin 4 is detachably installed on the other side of the driven plate 3, and one end of the anti-rotation pin 4 protrudes outward to form a protrusion 5;

[0027] It is convenient to insert the anti-rotation pin 4 into the inner side of the shaft groove 7 at one end of the workpiece shaft 6 to drive the workpiece shaft 6 to rotate, thereby processing the workpiece shaft 6.

[0028] In this embodiment, preferably, the elastic guide assembly 2 includes a connecting groove 201, a compression spring 202, and a guide rod 203. The connecting groove 201 is provided on the inner side of the mounting plate 1. The guide rod 203 is installed on the inner side of the connecting groove 201, and one end of the guide rod 203 is slidably engaged with the driven plate 3. The compression spring 202 is sleeved on the guide rod 203.

[0029] This facilitates the adjustment of the position of the driven plate 3, so that after changing different workpiece shafts 6, the elastic force of the compression spring 202 can be used to press the anti-rotation pin 4 into the inner side of the shaft groove 7 at the end of different workpiece shafts 6, so that the workpiece shaft 6 can be driven to rotate during subsequent processing.

[0030] In this embodiment, preferably, a bushing for guiding the shaft is provided on the inner side of the driven plate 3 corresponding to the guide shaft rod 203;

[0031] This facilitates improved wear resistance at the contact point between the inner side of the driven plate 3 and the guide shaft rod 203.

[0032] In this embodiment, preferably, the driven plate 3 has an assembly groove 9 on its inner side, and one end of the anti-rotation pin 4 is provided with a connecting seat that cooperates with the assembly groove 9, and the connecting seat and the assembly groove 9 are fixed by connecting bolts.

[0033] This facilitates easy replacement and maintenance should the anti-rotation pin 4 be damaged in the future.

[0034] In this embodiment, preferably, the driven plate 3 has a "T" shaped cross-section;

[0035] This facilitates better installation support for the anti-rotation pin 4.

[0036] In this embodiment, preferably, the elastic guide component 2 is provided in four locations along the circumference of the mounting plate 1;

[0037] This facilitates better elastic support and guidance for the driven plate 3.

[0038] In this embodiment, preferably, the mounting plate 1 is annular, and the outer diameter of the mounting plate 1 is the same as the outer diameter of the driven plate 3.

[0039] The working principle and usage process of this utility model are as follows: During use, the workpiece shaft 6 can be automatically loaded and unloaded by a robotic arm. When the spindle of the CNC grinding machine rotates, it drives the mounting plate 1 to rotate. The mounting plate 1 drives the driven plate 3 to rotate via the guide rod 203. The driven plate 3 drives the axial anti-rotation pin 4 to rotate. Under the force of the compression spring 202, the anti-rotation pin 4 enters the shaft groove 7 of the workpiece shaft 6, thereby driving the workpiece shaft 6 to rotate and realizing the rotation of the workpiece during the grinding process. Compared with the traditional grinding machine chuck, this rotary spindle transmission device saves manual clamping actions, facilitates automatic loading and unloading of CNC machines, and improves production efficiency. Compared with the power chuck, it does not require changes to the headstock center structure, does not affect the grinding machine accuracy, and preserves the original accuracy level of the grinding machine.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
