Description

Technical Field

[0001] This invention relates to the field of grinding technology, and more particularly to a wheel grinding head base. Background Technology

[0002] For some workpieces, grinding is usually required to remove discoloration or foreign matter from the surface.

[0003] Chinese patent CN214559777U discloses a grinding device comprising a moving device, a clamping device, and a grinding device. The moving device includes a linear displacement mechanism and a rotating mechanism, which can drive the clamping device to move linearly and rotate to adjust the angle between the product and the grinding device, controlling the grinding taper. The clamping device uses a diaphragm chuck to clamp the product, and the grinding device includes a grinding wheel with a protective cover. This device solves the problems of difficult taper control and high scrap rate associated with manual grinding, improving accuracy and efficiency.

[0004] However, the device lacks details in its transmission structure, and has no dedicated bearings, seals, or lubrication design, resulting in poor stability and lifespan. Secondly, the device adjusts the workpiece angle through a rotating mechanism and moves the workpiece position through a linear displacement mechanism, but does not involve the position adjustment of the grinding wheel itself, thus limiting its flexibility and application range.

[0005] Therefore, it is necessary to develop a wheel grinding head base to solve the above problems. Utility Model Content

[0030] Please refer to Figure 4The first bearing 34 is installed at one end near the driven wheel 31. Its inner ring is fixedly sleeved with the transmission rod 32, and its outer ring extends radially to abut against the inner surface of the fixed cylinder 33. Specifically, the first bearing 34 is a telescopic ball bearing, with a seal 36 and a first bearing cover 37 on its outer side. The seal 36 is fixedly sleeved with the transmission rod 32, and its outer surface extends axially towards the first bearing cover 37 to form a first oil baffle ring 361. The first bearing cover 37 is movably sleeved with the seal 36, and its outer ring extends to the outer side of the fixed cylinder 33 and is fixedly connected to the fixed cylinder 33 by bolts or screws. Its inner ring extends axially towards the seal 36 to form a first mating ring 371. The first oil baffle ring 361 and the first mating ring 371 are arranged alternately.

[0031] Preferably, the fixed cylinder 33 has a first oil injection hole 331, which penetrates the fixed cylinder 33 and is located on one side of the first bearing 34.

[0032] Please refer to Figure 5 The second bearing 35 is installed at one end near the grinding wheel 4. Its inner ring is fixedly sleeved on the transmission rod 32, and its outer ring extends radially and is fixedly connected to the inner surface of the fixed cylinder 33.

The second bearing cover 38 is sleeved on the transmission rod 32, and its outer ring extends to the outer side of the fixed cylinder 33. It is fixedly connected to the fixed cylinder 33 by bolts or screws. Its inner ring extends axially in the direction of the second oil baffle ring 321 to form a second mating ring 381.

[0034] Please refer to Figure 2 Furthermore, the present invention also includes an X-axis adjustment component 5 and a Y-axis adjustment component 6 for a wheel grinding head base.

[0035] The X-axis adjustment assembly 5 includes an X-axis drive member 51, a connecting rod 52 connected to the X-axis drive member 51, and a movable plate 53 fixedly connected to the connecting rod 52. The X-axis drive member 51 pushes the movable plate 53 to move in the X direction through the connecting rod 52.

[0036] The Y-axis adjustment assembly 6 includes a Y-axis drive member 61, a Y-axis transmission shaft 62 connected to the Y-axis drive member 61, and a lifting plate 63 fixedly connected to the Y-axis transmission shaft 62.

The bracket 1 is fixed on the lifting plate 63.

[0037] When using the wheel grinding head base of this utility model, after the drive component 2 is started, the driving wheel 21 at its output end begins to rotate, driving the driven wheel 31 to rotate synchronously via a belt. The rotation of the driven wheel 31 drives the transmission rod 32 to rotate, and the transmission rod 32 rotates stably within the fixed cylinder 33. The end of the transmission rod 32 away from the driven wheel 31 is connected to the grinding wheel 4, and the rotation of the transmission rod 32 drives the grinding wheel 4 to rotate. Under the drive of the drive component 2, the grinding wheel 4 continues to rotate, and by contacting the workpiece to be ground, it achieves grinding by utilizing its own rotation.

[0038] During processing, lubricating oil can be injected into the first bearing 34 through the first oil injection hole 331 of the fixed cylinder 33, and lubricating oil can be injected into the second bearing 35 through the second oil injection hole 332 to ensure the lubrication effect of the bearing.

[0039] When the position of the grinding wheel 4 needs to be adjusted to accommodate different workpieces, the X-axis drive component 51 pushes the moving plate 53 to move along the X-axis via the connecting rod 52, causing the Y-axis adjustment component 6 and the bracket 1 mounted on the moving plate 53 to move as a whole, thereby adjusting the X-axis position of the grinding wheel 4. The Y-axis drive component 61 pushes the lifting plate 63 to move along the Y-axis via the Y-axis transmission shaft 62. Since the bracket 1 is fixed on the lifting plate 63, it ultimately drives the grinding wheel 4 to adjust its Y-axis position.

[0040] This utility model is a wheel grinding head base, which is flexible and stable. Through the cooperation of double bearings and labyrinth seal design, combined with oil injection hole, the transmission stability is improved, wear is reduced and service life is extended. The X and Y direction adjustment components can finely adjust the position of the grinding wheel to adapt to more scenarios. In addition, the fixed cylinder provides more comprehensive protection for the transmission components, reducing failures. It is suitable for high-precision and long-term operation and has greater advantages in stability and reliability.

Any modifications, equivalent substitutions, improvements, etc., made within the principles of the present utility model should be included within the protection scope of the present utility model.
