Technical Field
[0001] This utility model relates to the field of automated grinding equipment technology, specifically to an electric spindle grinding wheel device for grinding equipment. Background Technology
[0002] Currently, spherical grinding machines for sapphire machining use a grinding wheel mechanism to drive the grinding wheel to grind the grinding wheel. However, the grinding wheel mechanism currently used is an asynchronous motor + pulley structure, which has a low speed, resulting in low cutting efficiency. The belt drive also has a certain amount of vibration, which leads to poor surface roughness of the workpiece and does not meet the requirements of high precision. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an electric spindle grinding wheel device.
[0004] The technical solution is as follows: an electric spindle grinding wheel device, comprising: a lower spindle seat, a grinding wheel spindle seat disposed on the lower spindle seat, a grinding wheel waterproof cover disposed at one end of the grinding wheel spindle seat, an electric spindle horizontally disposed on the grinding wheel spindle seat with its front end located outside the grinding wheel waterproof cover, and an electric spindle cover disposed on the grinding wheel spindle seat and covering the rear section of the electric spindle.
[0005] Preferably, the grinding wheel spindle seat includes a spindle seat base plate, a spindle mounting block integrally formed with the upper surface of the spindle seat base plate, a transverse spindle hole in the spindle mounting block, a bottom plate through hole in the spindle seat base plate and located behind the spindle mounting block, and a bottom plate dovetail groove in the bottom surface of the spindle seat base plate; a dovetail groove pad is provided on one side of the bottom plate dovetail groove.
[0006] Preferably, it also includes a locking screw and a locking handle located at the rear end of the locking screw; the front end of the locking screw passes through the rear end of the spindle seat base plate and abuts against the dovetail groove pad through the bottom plate through the hole.
[0007] Preferably, the lower spindle seat includes a lower base plate, a connecting block disposed on the lower base plate, an upper connecting plate disposed on the upper end of the connecting block, a spindle dovetail slide rail disposed on the upper surface of the upper connecting plate and connected to the dovetail groove of the base plate, and a spindle seat longitudinal through hole disposed in the grinding wheel spindle seat with its upper opening located in the spindle dovetail slide rail; the upper surface of the spindle dovetail slide rail is an inclined surface.
[0008] Preferably, the side of the spindle dovetail slide rail is provided with a mounting side plate, an adjusting screw with one end passing through the end face of the spindle dovetail slide rail and extending into the longitudinal through hole of the spindle seat, a transmission nut located at one end of the adjusting screw and in the longitudinal through hole of the spindle seat, and a spindle adjusting handle located at the other end of the adjusting screw and outside the mounting side plate; the transmission nut is connected to the bottom surface of the spindle seat base plate.
[0009] Preferably, the lower base plate, connecting block, upper connecting plate, and main shaft dovetail slide rail are connected by an integral molding method.
[0010] Technical Advantages: This invention employs an electric spindle to directly drive the grinding wheel. The electric spindle is mounted inside the grinding wheel spindle holder, eliminating the need for motor brackets, asynchronous motors, pulleys, belts, and other components. It features high speed, high precision, variable frequency speed control, and low vibration, while also saving space. Furthermore, the grinding wheel spindle holder is connected to the lower spindle holder, and the position and height of the grinding wheel spindle holder are adjustable, thereby allowing for adjustment of the position and height of the electric spindle.

Detailed Implementation
[0013] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0014] like Figure 1-5 As shown, this utility model embodiment provides an electric spindle grinding wheel device, which is installed on an automated grinding machine, including: a lower spindle seat 10, a grinding wheel spindle seat 20 installed on the lower spindle seat, a grinding wheel waterproof cover 30 installed at one end of the grinding wheel spindle seat, an electric spindle 40 horizontally installed on the grinding wheel spindle seat with its front end outside the grinding wheel waterproof cover, and an electric spindle cover 50 installed on the grinding wheel spindle seat and covering the rear section of the electric spindle. The electric spindle is a commercially available standard part.
[0015] The grinding wheel spindle seat 20 includes a spindle seat base plate 20a, a spindle mounting block 20b integrally formed with the upper surface of the spindle seat base plate, a transverse spindle hole 20c in the spindle mounting block, a bottom plate through hole 20d in the spindle seat base plate and located behind the spindle mounting block, and a bottom plate dovetail groove 20e in the bottom surface of the spindle seat base plate; a dovetail groove pad 60 is provided on one side of the bottom plate dovetail groove.
[0016] It also includes a locking screw 70 and a locking handle 80 located at the rear end of the locking screw; the front end of the locking screw passes through the rear end of the spindle seat base plate and abuts against the dovetail groove pad through the bottom plate through hole 20d.
[0017] The lower spindle seat 10 is installed on the cabinet of the automated grinding equipment, including a lower base plate 10a, a connecting block 10b on the lower base plate, an upper connecting plate 10c on the upper end of the connecting block, a spindle dovetail slide rail 10d on the upper surface of the upper connecting plate and connected to the dovetail groove 20e of the base plate, and a spindle seat longitudinal through hole 10e located inside the grinding wheel spindle seat 20 with its upper opening located inside the spindle dovetail slide rail. The upper surface of the spindle dovetail slide rail 10d is an inclined plane, that is, the upper surface of the lower base plate 10a is a horizontal plane, and the upper surface of the spindle dovetail slide rail and the upper surface of the lower base plate form an angle greater than zero degrees. The upper surface of the spindle dovetail slide rail has a taper of 1:100 with the horizontal plane to adjust the installation height of the grinding wheel spindle seat 20, thereby adjusting the height of the electric spindle 40 to adapt to the automated grinding equipment.
[0018] A mounting side plate 90 is provided on the side of the spindle dovetail slide rail 10d. An adjusting screw 100, one end of which passes through the end face of the spindle dovetail slide rail and extends into the longitudinal through hole 10e of the spindle seat, has a transmission nut 110 located at one end of the adjusting screw and within the longitudinal through hole of the spindle seat, and a spindle adjusting handle 120 located at the other end of the adjusting screw and outside the mounting side plate. The transmission nut is connected to the bottom surface of the spindle seat base plate 20a. The end face of the spindle dovetail slide rail has a transverse through hole 10f communicating with the longitudinal through hole 10e of the spindle seat. The end of the adjusting screw 100 extends from the transverse through hole into the longitudinal through hole of the spindle seat. In use, rotating the adjusting screw drives the transmission nut 110 to move on the adjusting screw, thereby moving the spindle seat base plate and the grinding wheel spindle seat 20, thus adjusting the position and height of the electric spindle 40.
[0019] The lower base plate 10a, connecting block 10b, upper connecting plate 10c, and spindle dovetail slide rail 10d are connected by an integral molding method, such as a common metal machining process.
