[0002] When grinding automotive parts, it is necessary to place the product next to the grinder, place the product opposite to the grinder, and rotate the product to force the grinder to grind the product. Due to the high requirements on product roundness, runout, and tolerance, a heart-shaped chuck is generally used to reversely clamp the spindle to drive the product workpiece to rotate.

[0003] In the existing patent 201320684428.3, a grinder chuck ring is provided, on which two spaced clamping bolts are radially threaded and a clamping handle is hinged, one end of the clamping handle extends into the grinder chuck ring, and the other end extends to the outside of the grinder chuck ring. The handle is connected to a tension spring, and a concave-convex structure for increasing friction is provided on the arc surface of the clamping handle. The utility model has the advantages of stronger clamping force and higher workpiece processing accuracy, and solves the problem that the contact surface between the clamping handle and the workpiece of the existing heart-shaped chuck for grinders is a smooth metal surface, which makes the fixation of the workpiece not reliable enough, and causes deviation of the workpiece due to slipping, resulting in low processing accuracy.

[0004] In the above structure, since the workpiece is subjected to force at a single point and has poor stability, it cannot meet the requirements of continuous stable processing, which reduces the stability of the device and is not conducive to the processing of product workpieces. At the same time, it increases the chance of human reverse installation errors, which can easily lead to reverse collisions, reduce the service life of the device, affect the quality of product workpieces, and reduce the service life of the grinding wheel. Utility Model Content

[0005] In view of this, the purpose of the utility model is to propose a grinding machine drive error prevention device to solve the problem of single-point force on the workpiece, poor stability, inability to meet continuous stability processing, reduced stability of the device, increased the chance of human reverse installation errors, and easily lead to the problem of reverse collision of the machine.

[0006] Based on the above purpose, the utility model provides a grinder drive error prevention device, comprising a grinder mechanism arranged on a mounting surface, a blocking assembly being arranged on the grinder mechanism, a limiting mechanism being arranged at the other end of the mounting surface, a workpiece body being installed between the grinder mechanism and the limiting mechanism, a clamping mechanism being arranged on the workpiece body at the output end of the grinder mechanism, the clamping mechanism being used to clamp the workpiece body, wherein the blocking assembly blocks the clamping mechanism, and the rotation of the grinder mechanism forces the blocking assembly to rotate, thereby forcing the clamping mechanism to drive the workpiece body to rotate, so that the output end of the grinder mechanism processes the workpiece body.

[0007] Preferably, the grinding machine mechanism comprises a rotating disk with bearings mounted on the mounting surface, and a grinding head for processing the workpiece body is arranged on the rotating disk, and the grinding head is used to support the workpiece body.

[0008] Preferably, the blocking assembly includes a blocking rod disposed on the rotating disk, and the blocking rod is used to block the clamping mechanism.

[0009] Preferably, the clamping mechanism comprises a clamping ring arranged on the workpiece body, and the inner ring of the clamping ring and the outer ring of the workpiece body are provided with engaging teeth and grooves.

[0010] Preferably, the outer ring of the clamping ring is provided with a pole ear, and the blocking rod is in abutment with the pole ear.

[0011] Preferably, the limiting mechanism comprises an ejector pin arranged at one end of the mounting surface, the ejector pin is used to support the end of the workpiece body, and the ejector pin and the grinding head form a clamping connection with the workpiece body.

[0012] The beneficial effects of the utility model are as follows: the product workpiece body is installed between the grinding machine mechanism and the limiting mechanism, the clamping mechanism is installed on the workpiece body and abutted against the blocking component. When the workpiece body is processed, the grinding machine mechanism is started. Since the blocking component is located in an eccentric position, the rotation of the grinding machine mechanism drives the blocking component to rotate, and the blocking component drives the clamping mechanism to move. Under the action of the limiting mechanism, the clamping mechanism drives the workpiece body to rotate. At this time, the grinding machine mechanism grinds the workpiece body to complete the processing of the workpiece body. In summary, a grinder drive error prevention device of the present application can meet the continuous stability processing of the product, improve the stability of the device, facilitate the processing of the product, reduce the chance of human reverse installation errors, reduce the possibility of installation collisions, increase the service life of the device, improve the quality of the product, and increase the service life of the grinding wheel.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a grinder drive error prevention device includes a grinder mechanism 1 arranged on a mounting surface, a blocking component 2 is arranged on the grinder mechanism 1, a limiting mechanism 3 is arranged at the other end of the mounting surface, a workpiece body 4 is installed between the grinder mechanism 1 and the limiting mechanism 3, and a clamping mechanism 5 is arranged on the workpiece body 4 at the output end of the grinder mechanism 1, and the clamping mechanism 5 is used to clamp the workpiece body 4, wherein the blocking component 2 blocks the clamping mechanism 5, and the rotation of the grinder mechanism 1 forces the blocking component 2 to rotate, thereby forcing the clamping mechanism 5 to drive the workpiece body 4 to rotate, so that the output end of the grinder mechanism 1 processes the workpiece body 4.

[0020] Working principle: install the product workpiece body 4 between the grinding machine mechanism 1 and the limiting mechanism 3, install the clamping mechanism 5 on the workpiece body 4, and abut against the blocking component 2. When processing the workpiece body 4, start the grinding machine mechanism 1. Since the blocking component 2 is located in an eccentric position, the rotation of the grinding machine mechanism 1 drives the blocking component 2 to rotate, and the blocking component 2 drives the clamping mechanism 5 to move. Under the action of the limiting mechanism 3, the clamping mechanism 5 drives the workpiece body 4 to rotate. At this time, the grinding machine mechanism 1 grinds the workpiece body 4 to complete the processing of the workpiece body 4. In summary, a grinder drive error prevention device of the present application can meet the continuous stability processing of the product, improve the stability of the device, facilitate the processing of the product, reduce the chance of human reverse installation errors, reduce the possibility of installation collisions, increase the service life of the device, improve the quality of the product, and increase the service life of the grinding wheel.

[0021] like Figure 1 and Figure 2 As shown, a grinding machine driving error prevention device, the grinding machine mechanism 1 includes a rotating disk 101 with a bearing mounted on a mounting surface, and a grinding head 102 for processing a workpiece body 4 is arranged on the rotating disk 101, and the grinding head 102 is used to support the workpiece body 4.

[0022] Working principle: The system controls the rotating disk 101 to rotate, and the rotating disk 101 drives the grinding head 102 to rotate. The grinding head 102 grinds the workpiece body 4 and limits the workpiece body 4 at the same time, and drives the blocking component 2 to rotate. The setting of the grinding machine mechanism 1 facilitates the grinding of the workpiece body 4 and limits the workpiece body 4 at the same time. While the workpiece body 4 is being ground, the workpiece body 4 is clamped to improve the stability of the device and improve flexibility.

[0023] like Figure 1 and Figure 2 As shown, a grinding machine drive error prevention device, the blocking component 2 includes a blocking rod 201 arranged on the rotating disk 101, the blocking rod 201 is arranged perpendicular to the rotating disk 101, and the blocking rod 201 is located at the eccentric position of the rotating disk 101, and the blocking rod 201 is used to block the clamping mechanism 5.

[0024] Working principle: When the rotating disk 101 rotates, the blocking rod 201 is also driven to rotate. The blocking rod 201 generates a force on the clamping mechanism 5, forcing the clamping mechanism 5 to drive the workpiece body 4 to rotate. The setting of the blocking component 2 uses the same driving source to improve the rationality and flexibility of the device, and at the same time indirectly generates a force on the clamping mechanism 5, so that the clamping mechanism 5 moves synchronously, forcing the device to continue stable processing.

[0025] like Figure 1 and Figure 3 As shown, a grinding machine driving error prevention device, the clamping mechanism 5 includes a clamping ring 501 arranged on the workpiece body 4, the inner ring of the clamping ring 501 and the outer ring of the workpiece body 4 are provided with engaging tooth grooves 502, and there are multiple tooth grooves 502, which are arranged in a circumferential shape.

[0026] like Figure 1 and Figure 3 As shown, a grinding machine driving error prevention device, the outer ring of the clamping ring 501 is provided with a pole ear 503, in this solution, two pole ears 503 are provided, and the blocking rod 201 is in contact with the pole ears 503.

[0027] Working principle: the baffle rod 201 rotates, and the pole ear 503 is forced to rotate with the baffle rod 201 due to the contact between the pole ear 503 and the baffle rod 201, and the pole ear 503 drives the clamping ring 501 to rotate. Under the action of the engagement of the tooth groove 502 of the inner ring of the clamping ring 501 and the outer ring of the workpiece body 4, the clamping ring 501 is forced to drive the workpiece body 4 to rotate, so that the grinding head 102 performs a processing operation on the workpiece body 4. The setting of the clamping mechanism 5 can transfer the force on the baffle rod 201 to the workpiece body 4, thereby driving the workpiece body 4 to rotate, forcing the workpiece body 4 and the grinding head 102 to form friction, thereby grinding the workpiece body 4; the setting of the pole ear 503 makes it easy to apply the force on the baffle rod 201 to the clamping ring 501, providing a fulcrum, which is convenient for the baffle rod 201 to act on the clamping ring 501. Two pole ears 503 are set to improve the balance and stability of the device.

[0028] like Figure 1 As shown, a grinding machine driving error prevention device, the limiting mechanism 3 includes a pin 301 arranged at one end of the mounting surface, the pin 301 is used to support the end of the workpiece body 4, and the pin 301 and the grinding head 102 form a clamping connection with the workpiece body 4.

[0029] Working principle: In order to improve the stability and rationality of the workpiece body 4, the end of the workpiece body 4 is supported by the ejector pin 301. Since the head of the ejector pin 301 is sharp and compatible with the workpiece body 4, it will not cause damage to the workpiece body 4. The setting of the limit mechanism 3 is used in conjunction with the grinding head 102 to form a clamping effect on the workpiece body 4, thereby improving the stability of the workpiece body 4, improving the quality of the product workpiece body 4, and improving the accuracy of processing.
