Description

Technical Field

[0001] This utility model belongs to the technical field, and specifically relates to an automatic grinding device for plunger ball heads. Background Technology

[0002] A plunger ball head is a special mechanical connector widely used in applications requiring angle adjustment and rotational flexibility. It typically consists of a plunger with a spherical head and a matching cup-shaped seat, allowing it to swing or rotate freely within a certain range, thus adapting to more complex working environments.

[0003] Existing automatic plunger ball head grinding devices work by placing the plunger ball head to be ground in a designated position, then starting a motor to control a three-rotor chuck to clamp and fix the plunger ball head to be ground. The grinding head is then mounted on the grinding module, and the grinding head rotates under the control of a motor. During rotation, the position of the grinding head is adjusted by various electronic control devices such as cylinders and motors, allowing the grinding head to grind the plunger ball head quickly and stably. However, in actual use, before the grinding operation, personnel need to pre-control the position of the grinding head to ensure that it is in the optimal position for grinding the plunger ball head, and then start the equipment to move the grinding head around the rotating plunger ball head. This pre-adjustment of the grinding head position is cumbersome, time-consuming, and labor-intensive, which may prolong the grinding time of the plunger ball head and reduce processing efficiency. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an automatic grinding device for plunger ball heads. It can quickly and stably adjust the position of the plunger ball head when needed, is simple and convenient to operate, and is easy for processing personnel to use, which can effectively improve processing efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an automatic grinding device for plunger ball heads, including a bracket, with evenly distributed support feet on the lower surface of the bracket, a mounting plate on the upper surface of the bracket, a spindle box on the upper surface of the mounting plate, a rotating rod rotatably mounted inside the spindle box, a chuck at one end of the rotating rod near the vertical center of the bracket, symmetrically distributed slide rails on the upper surface of the mounting plate, and sliding seats slidably mounted between the slide rails. An electrical control module for driving the chuck to rotate is also mounted on the bracket, and a grinding module for grinding is also mounted on the sliding seats. The electrical control module includes a driven pulley fixedly sleeved on the outer arc surface of the rotating rod, a drive motor mounted on the bottom of the bracket via a mounting seat, a drive pulley fixedly sleeved on the output shaft of the drive motor, and a transmission belt connecting the drive pulley and the driven pulley. A material collection trough is formed on the upper surface of the mounting plate, and a waste bin cooperating with the material collection trough is provided on the lower surface of the mounting plate.

[0008] As a further improvement of this utility model, a control box is provided on the upper surface of the mounting plate, and the drive motor, electric push rod one, electric push rod two, servo motor one and servo motor two are all electrically connected to the control box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Secondly, the operation of the electric push rod is controlled by the control box, so that the extension end of the electric push rod drives the sliding seat connected to it to slide between the slide rails, thereby further stabilizing and adjusting the position of the grinding head, so that the grinding head can quickly and stably adapt to the position of the plunger ball head for grinding.

The inner bottom of the bracket 101 is equipped with a drive motor 108 through a mounting seat. The output shaft of the drive motor 108 is fixedly sleeved with a driving pulley 109. A transmission belt 110 is provided between the driving pulley 109 and the driven pulley 107.

[0023] like Figure 2 , 3 As shown, the grinding module includes a semi-circular sliding rail 214 disposed on the upper surface of the sliding seat 202. A drive box 213 is slidably disposed on the upper side of the semi-circular sliding rail 214. A guide rail 208 is disposed on the upper surface of the drive box 213. A slide table 209 is slidably disposed on the upper side of the guide rail 208. A servo motor 210 is disposed on the upper surface of the slide table 209. The output shaft of the servo motor 210 is fixedly sleeved with a grinding head 211. An electric push rod 212 is disposed in a clearance groove opened on the guide rail 208. The telescopic end of the electric push rod 212 is connected and fixed to the slide table 209. An adjustment unit for adjusting the position of the sliding seat 202 is also provided on the mounting plate 103. The drive box 213 is also provided with... The drive housing 213 is equipped with a moving unit for driving the drive housing 213 to move; the adjusting unit includes a support plate 203 disposed between slide rails 201, and an electric push rod 204 is disposed in each of the mounting slots on the support plate 203. The telescopic ends of the electric push rods 204 are connected and fixed to the sliding seat 202; the moving unit includes a semi-helical gear ring 207 disposed on the upper surface of the sliding seat 202; a rotating shaft 205 is rotatably disposed inside the drive housing 213; a helical gear is fixedly sleeved on the outer arc surface of the rotating shaft 205; the helical gear meshes with the semi-helical gear ring 207; a servo motor 206 is disposed inside the drive housing 213; the output shaft of the servo motor 206 is fixed to the rotating shaft 205 by a coupling.

[0024] like Figure 1 , 4 As shown, a control box 301 is provided on the upper surface of the mounting plate 103. The drive motor 108, electric push rod 1 204, electric push rod 212, servo motor 1 206 and servo motor 210 are all electrically connected to the control box 301.

[0025] During use, the plunger ball head that needs to be ground is placed on the chuck 106, so that the chuck 106 clamps and fixes the plunger ball head, and clamps the plunger ball head quickly and stably.

[0026] The control box 301 controls the operation of electric push rod 204, causing the telescopic end of electric push rod 204 to drive the sliding seat 202 connected to it to slide between the slide rails 201.

[0027] The drive motor 108 is controlled by the control box 301, which causes the output shaft of the drive motor 108 to drive the active pulley 109 connected to it to rotate. In turn, the active pulley 109 drives the rotating rod 105 where the driven pulley 107 is located to rotate through the transmission belt 110, so that the chuck 106 drives the clamped and fixed plunger ball head to rotate stably.

[0028] The control box 301 regulates the operation of servo motor 206 and servo motor 210, causing the output shaft of servo motor 210 to drive the grinding head 211 connected to it to rotate. The output shaft of servo motor 206 drives the helical gear connected to it to rotate. Then, through the meshing relationship between the helical gear and the semi-helical gear ring 207, the drive box 213 is driven to slide on the upper side of the semi-circular sliding rail 213. This allows the drive box 213 to drive the rotating grinding head 211 to rotate stably around the plunger ball head, thereby performing stable grinding on the plunger ball head.
