Description

Technical Field

[0001] The present invention relates to the technical field related to tappet surface processing technology, and in particular to a tappet surface processing device. Background Art

[0002] The production of tappets involves multiple steps, among which surface treatment is crucial. This involves polishing and coating the tappets. During use, the tappet's end face directly contacts the camshaft, subjecting it to high-frequency sliding friction and impact loads. Polishing the end face significantly reduces friction, wear, and heat buildup, thereby extending service life. Coating the tappet's outer circumference enhances fatigue and scratch resistance, improves surface oil retention, and enhances boundary lubrication.

[0003] Figure 14 The figure shows the simple structure of a tappet 6, which is cylindrical in shape with an open bottom. A ring plate 61 is provided on the inner circumference of the tappet 6, which has a bottom opening 62. The conventional polishing method involves placing a large number of tappets 6 on a workbench in a disorderly manner. Each tappet 6 is then manually held and placed on the polishing side of a polishing wheel for polishing. The polished tappets 6 are then placed on another workbench. This method is labor-intensive and difficult to control the force with which the tappets 6 contact the polishing wheel during polishing. This results in uneven polishing of each tappet 6.

[0004] Figure 1 The simple structure of the coating machine 5 is shown in FIG. 5 , wherein the coating chamber 51 which can be opened is mounted on a base plate 54 , and a control box 55 is also provided on the base plate 54 . Figure 15 As shown, a workpiece rack 52 is provided for tappets 6, and a plurality of placement rods 53 are provided on its side for placing each tappet 6. The conventional method is to manually place the tappets 6 one by one on the placement rods 53, and then remove the tappets 6 one by one after the coating is completed and collect them. This method is also labor-intensive. Summary of the Invention

[0005] In view of the above-mentioned defects, the present invention provides a tappet surface treatment device, which can improve the efficiency of tappet polishing and coating and reduce manual operations.

[0006] In order to achieve the purpose of the present invention, the following technologies are proposed: A tappet surface treatment device is provided at one end of a coating machine and includes: The transfer unit includes a first linear mechanism. A second linear mechanism is provided at the sliding end of the first linear mechanism. An outer frame is provided at the output end of the second linear mechanism. A square opening is formed at one end of the outer frame facing the coating machine. An inner frame is provided inside the outer frame.

When placing the tappet, the outer peripheral side of the top pipe abuts against the inner peripheral side of the bottom opening of the tappet. A ring opening matching the pipe rack is formed at the lower end of the top pipe. The polishing unit includes a polishing assembly provided above the transfer unit and a top feeding assembly provided below the transfer unit. The polishing assembly is used to polish the end face of a single tappet, and the top feeding assembly is used to jack up a single tappet upward so that it contacts the polishing assembly. The switching unit is provided at one end of the transfer unit and is used to transfer each tappet between the inner frame and the loading and unloading unit. The loading and unloading unit is provided at one end of the switching unit and includes a fifth linear mechanism arranged parallel to the first linear mechanism. A third rotary motor is vertically provided at the sliding end of the fifth linear mechanism. A clamping assembly is provided at the upper end of the output shaft of the third rotary motor and is used to clamp each tappet simultaneously.

[0007] Furthermore, the polishing assembly includes a first rotary motor arranged vertically, and a polishing wheel is provided at the lower end of its output end.

[0008] Furthermore, the switching unit includes a second rotary motor. One end of its output shaft is provided with a fourth linear mechanism. One end of the output shaft of the fourth linear mechanism is provided with a receiving block, and a receiving groove matching the square plate is formed at one end of the receiving block.

[0009] Furthermore, the clamping assembly includes an F-shaped frame. Sixth linear mechanisms with opposite output directions are respectively provided at one ends of its two horizontal sides.

[0010] The beneficial effects of this technical solution are as follows: [[ID=##]]1. The processes of polishing and coating the tappets are combined. Only need to place each tappet at the beginning and remove each tappet after all are completed, reducing the material removal during polishing, or the sorting process, and reducing the separate feeding process during coating, which can reduce a large amount of manual operations and improve production efficiency.

More specifically, the first linear mechanism 11 is provided on a pair of first brackets 111, and the chute 17 is provided on a pair of second brackets.

[0030] The polishing unit 2 includes a polishing assembly disposed above the transfer unit 1 and a blanking assembly disposed below the transfer unit 1. The polishing assembly is used to polish the end face of a single tappet 6, and the blanking assembly is used to jack up a single tappet 6 upward to make it contact the polishing assembly. The polishing assembly includes a first rotating motor 21 arranged vertically. At the lower end of the output end of the first rotating motor 21, there is a polishing wheel 22. Guard plates 221 covering 3 / 4 of its circumference are provided on the upper, lower and outer peripheral sides of the polishing wheel 22. The blanking assembly is provided with a vacuum pump 23. The suction end of the vacuum pump 23 is provided with a connecting pipe 24, which includes a horizontal part and a 90° elbow. The upper end of the 90° elbow is connected with a telescopic hose 241. The upper end of the telescopic hose 241 is provided with a vertical pipe 242. The upper end of the vertical pipe 242 is provided with a connecting pipe 25 for upwardly penetrating into the vertical hole 143. Specifically, a tapered pipe is also connected between the vertical pipe 242 and the connecting pipe 25. When the connecting pipe 25 penetrates into the vertical hole 143, the outer peripheral side of the connecting pipe 25 abuts against the inner peripheral side of the vertical hole 143. The inner diameter of the connecting pipe 25 is the same as the inner diameter of the top pipe 16. The blanking assembly also includes a third linear mechanism 26 arranged vertically.

A receiving groove 35 matching the square plate 141 is opened at one end of the receiving block 34. More specifically, the second rotating motor 31 is arranged on a fourth bracket 32.

[0032] The loading and unloading unit 4 is provided at one end of the switching unit 3, and the switching unit 3 is located between the transfer unit 1 and the loading and unloading unit 4. The loading and unloading unit 4 includes a fifth linear mechanism 41 arranged in parallel with the first linear mechanism 11, and a clamping assembly for simultaneously clamping each tappet 6. A third rotary motor 42 is vertically provided at the sliding end of the fifth linear mechanism 41. The clamping assembly includes an F-shaped frame 421 provided at the upper end of the output shaft of the third rotary motor 42. At one end of each of its two horizontal sides, a sixth linear mechanism 43 with opposite output directions is provided. At one end of the output shaft of the sixth linear mechanism 43, a lifting plate 431 is provided. At one end of the lifting plate 431, a rotating plate 432 perpendicular to it is provided. At one end of the rotating plate 432, a vertical plate 44 is provided. On one side surface of the vertical plate 44, a plurality of horizontal plates 441 are provided along the vertical direction. On one side surface of the horizontal plate 441, a plurality of extension plates 45 are provided. At one end of the extension plate 45, a clamping block 46 is provided. An arc-shaped groove 47 matching the outer peripheral side of the tappet 6 is provided on the upper end surface or the lower end surface of the clamping block 46. Specifically, each clamping block 46 connected to each extension plate 45 on one side of a vertical plate 44 has an arc-shaped groove 47 on the upper end surface, and each clamping block 46 connected to each extension plate 45 on one side of the other vertical plate 44 has an arc-shaped groove 47 on the lower end surface. The clamping blocks 46 with arc-shaped grooves 47 on the upper end surface and the clamping blocks 46 with arc-shaped grooves 47 on the lower end surface are arranged in pairs one by one for clamping the tappet 6. More specifically, the fifth linear mechanism 41 is provided on a pair of fifth brackets.

[0033] In this embodiment, the first linear mechanism 11 and the fifth linear mechanism 41 adopt a rodless linear cylinder or a linear guide rail, and the second linear mechanism 12, the third linear mechanism 26, the fourth linear mechanism 33, and the sixth linear mechanism 43 adopt a single-axis linear cylinder or a linear hydraulic cylinder.

[0034] Working mode: In the initial state, as Figure 1 shown, the inner frame 14 is horizontal, and as Figure 4 shown, the top pipe 16 is on the pipe rack 15. Figure 5 is used to separately display the top pipe 16 and the pipe rack 15. Tappets 6 are placed on the top pipe 16 respectively. At the very beginning, the area where the polishing wheel 22 is not covered by the guard plate 221 is located above a tappet 6. The tappet 6 mentioned here is located at a position close to a corner of the inner frame 14 inside the inner frame 14. Therefore, it can be seen that the sliding end of the first linear mechanism 11 is currently relatively close to the switching unit 3, and as Figure 1 or Figure 2 shown, the slider 133 does not extend out of the through groove by a large distance.

[0035] Next, start the vacuum pump 23. By means of air extraction, the tappet 6 can move more stably, thus solving the problem that the contact force between the tappet 6 and the polishing wheel 22 is inconsistent during polishing. Raise the connecting pipe 25 through the third linear mechanism 26 so that it enters the vertical hole 143, and further push the top pipe 16 to rise. Since the outer peripheral side of the top pipe 16 abuts against the inner peripheral side of the bottom port 62, and at the same time air is being extracted inside the pipe, and the pipe holder 15 and the top pipe 16 are in sliding fit, the tappet 6 rises relatively stably. The tappet 6 contacts the polishing wheel 22 and is then polished. Then lower the tappet 6 so that the top pipe 16 returns to the pipe holder 15, and then pause the air extraction.

[0036] And so on, move the other tappets 6 to the polishing positions in turn through the first linear mechanism 11 and the second linear mechanism 12 for polishing until the end faces of all the tappets 6 are polished.

[0037] Then, move the outer frame 13 through the second linear mechanism 12 so that the square plate 141 can correspond to the receiving groove 35. Then move the outer frame 13 through the first linear mechanism 11 so that the square plate 141 is inserted into the receiving groove 35. Then make the inner frame 14 rise a small distance through the fourth linear mechanism 33 to disengage from the outer frame 13, and then rotate the inner frame 14 to be vertical through the second rotary motor 31.

[0038] Then make one end of the clamping assembly approach each tappet 6 through the fifth linear mechanism 41, and make each pair of clamping blocks 46 clamp the tappet 6 through two sixth linear mechanisms 43. Then move each tappet 6 out through the fifth linear mechanism 41. Preferably, as described above, the pipe holder 15 is made of rubber, the top pipe 16 is made of metal material, and the tappet 6 is also metal. This makes it difficult for the top pipe 16 to be taken out from the outer peripheral side of the pipe holder 15 simultaneously when the tappet 6 is moved out.

[0039] Then rotate the clamping assembly 180° through the third rotary motor 42. The staff opens the door of the coating chamber 51, and then pushes each tappet 6 onto each placing rod 53 through the fifth linear mechanism 41 to prepare for coating. Then move out the clamping assembly, close the door of the coating chamber 51, and perform coating.

[0040] After coating is completed, open the door of the coating chamber 51 again. By analogy with the above steps, take out each tappet 6, and then remove the tappet 6.

[0041] The above are only some embodiments listed in this application and do not limit this application.
