Description

Technical Field

[0001] This utility model relates to the field of grinding head manufacturing technology, specifically to a grinding head manufacturing centering device. Background Technology

[0002] A grinding head is a general term for a small, shanked grinding tool used in electric grinders, pendant grinders, and hand drills. There are many types, including ceramic grinding heads, rubber grinding heads, diamond grinding heads, and abrasive cloth grinding heads. Ceramic grinding heads: The abrasive grains (generally brown corundum, white corundum, chromium corundum, or silicon carbide) are sintered from a ceramic binder, with a metal shank in the center. They are mainly used for grinding various metals, for grinding the inner walls of holes, and for mold correction.

[0003] In the production of existing ceramic grinding heads, grinding head rods need to be installed on the grinding head. However, it is impossible to ensure that each grinding head rod is inserted into the grinding head rod groove of the grinding head in a centered manner, which affects subsequent processing and product quality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing ceramic grinding heads cannot guarantee that the grinding head rod can be accurately inserted into the grinding head during production, which affects subsequent processing and product quality.

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

[0006] A grinding head production centering device, characterized in that: it includes a grinding head clamping fixture disposed on a grinding head turntable for holding the grinding head body, an L-shaped motor frame disposed on one side of the grinding head turntable, a centering motor mounted on the motor frame, one end of the centering motor being fixedly connected to a cylinder seat, and a pneumatic gripper assembly for holding the grinding head rod being mounted on the other end of the cylinder seat, the pneumatic gripper assembly including a first centering gripper and a second centering gripper.

[0007] A further improvement is that a first centering rod groove is provided on the end face of the first centering jaw facing the grinding head rod.

[0008] A further improvement is that a second centering rod groove is provided on the end face of the second centering jaw facing the grinding head rod.

[0009] A further improvement is that the first and second centering rod grooves are combined to form a complete grinding head rod centering groove.

[0010] A further improvement is that, after the pneumatic gripper assembly clamps the grinding head rod, the grinding head rod centering groove is aligned with the grinding head rod groove of the grinding head body for inserting the grinding head rod.

[0011] A further improvement is that a fixed sleeve is installed on one end of the motor frame near the gripper drive device, and the output end of the centering motor is fixedly connected to the cylinder seat through the fixed sleeve. The cylinder seat is rotatably mounted on the end of the fixed sleeve facing the gripper drive device.

[0012] A further improvement is that a motor frame drive cylinder is provided below the motor frame to drive the entire device to move in the direction of the grinding head, and the output end of the motor frame drive cylinder is fixedly connected to the bottom surface of the motor frame.

[0013] Compared with existing technologies, the above technical solution has the following advantages:

[0014] The inserted grinding head rod can be aligned into the grinding head rod groove of the grinding head, ensuring the installation accuracy of the grinding head rod, improving product quality, and the structure is simple and easy to implement. Attached Figure Description

[0021] See Figures 1-4As shown, the technical solution adopted in this specific embodiment is: a grinding head production centering device, characterized in that: it includes a grinding head clamp 91 set on the grinding head turntable 9 for clamping the grinding head body 8, an L-shaped motor frame 1 set on one side of the grinding head turntable 9, a centering motor 2 installed on the motor frame 1, one end of a cylinder seat 4 fixedly connected to the output end of the centering motor 2, and a pneumatic gripper assembly 5 for clamping the grinding head rod 81 installed on the other end of the cylinder seat 4, the pneumatic gripper assembly 5 including a first centering gripper 6 and a second centering gripper 7.

[0022] The first centering jaw 6 has a first centering groove 61 on one end face facing the grinding head rod 81; the second centering jaw 7 has a second centering groove 71 on one end face facing the grinding head rod 81.

[0023] The first centering rod groove 61 and the second centering rod groove 71 are combined to form a complete grinding head rod centering groove.

[0024] When the two centering jaws clamp the grinding head rod, the centering groove of the grinding head rod is aligned with the grinding head rod groove 82 of the grinding head body 8 for inserting the grinding head rod 81.

[0025] The motor frame 1 is equipped with a fixed sleeve 3 at one end near the pneumatic gripper assembly 5. The output end of the centering motor 2 is fixedly connected to the cylinder seat 4 through the fixed sleeve 3. The cylinder seat 4 is rotatably mounted on the end of the fixed sleeve 3 facing the pneumatic gripper assembly 5.

[0026] The motor frame 1 is provided with a motor frame drive cylinder 10 below it, which is used to drive the entire device to move in the direction of the grinding head. The output end of the motor frame drive cylinder 10 is fixedly connected to the bottom surface of the motor frame 1.

[0027] The working principle of this utility model is as follows: When the grinding head body is equipped with the grinding head rod, it is driven to rotate to the centering jaws by the grinding head turntable. The two centering jaws of the pneumatic jaw assembly hold the grinding head rod in the grinding head rod centering groove. Then, the centering motor drives the cylinder seat to rotate, and the corresponding two centering jaws rotate, which drives the held grinding head rod to rotate. Since the grinding head rod centering groove is aligned with the grinding head rod groove of the grinding head body for inserting the grinding head rod, after rotating a few times, the grinding head rod can be centered in the grinding head rod groove of the grinding head body.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions provided are merely illustrative of the principles of this utility model.
