Description

TECHNICAL FIELD

[0001] The utility model belongs to special vehicle assembly technical field, concretely relates to a kind of special vehicle press fitting equipment of auxiliary tooling can be switched quickly. BACKGROUND

[0002] In order to improve the efficiency of track, reduce the noise and impact generated by track in the process of vehicle driving, the equal polygonal hard rubber ring is installed on the hub of driving wheel of special vehicle, so that track plate is just laid on a plane of rubber ring after track and driving wheel enter engagement, the purpose of stable transmission, reducing impact and noise is achieved, and the technology is widely used in engineering machinery field such as energy, heavy industry, underground operation.

[0003] Rubber ring is integrally formed with connecting ring, and rotation of rubber ring is prevented by using friction force under interference fit with driving wheel hub.Press fitting rubber ring needs to ensure its installation direction and angle, and interference amount is large, so pressure machine is used for press fitting, and it is not detachable, and it must be ensured that press fitting is successful once.

[0004] When press fitting rubber ring, metal piece fitted with rubber ring has no chamfer, and inner diameter of rubber ring is smaller than outer diameter of metal piece, which belongs to tight fit, and rubber ring itself is soft, so many positions cannot be directly put in when directly fitted by hand, and rubber ring is sheared when press machine is pressed down, so rubber ring is not installed in place, and rubber ring is damaged, even cut off;In addition, manual assembly is time-consuming and laborious, and efficiency is low.

[0005] Now, press fitting mainly uses special tooling for single press fitting, and personnel is needed in whole process of press fitting, so labor intensity is large, and speed is slow, and specific press fitting steps are as follows: after driving wheel is hoisted and fixed on press fitting table, driving wheel rubber ring is placed, and then pressure disc welding assembly is pressed;After adjusting position, positioning pin is loaded, then appropriate fine adjustment is carried out by using scale line, and then press fitting is carried out;After press fitting is completed, scale line is used for inspection.

[0006] As shown in Figures 1-4 , press fitting tooling is composed of pressure disc welding assembly 12 and positioning pin 13.Pressure disc welding assembly 12 is used as main component, and its structure is as shown in Figure 5 and 6As shown, the pressure plate 1201 and the positioning block 1202 are composed of material selected from alloy structural steel or high-quality carbon steel. Among them, the outer size of the pressure plate 1201 is approximately the same as that of the driving wheel rubber ring, and is uniformly provided with positioning holes 1203 with the same size and position as the process holes on the driving wheel 14 and the rubber ring 15. By passing the positioning pin 13 through the positioning hole 1203, the rubber ring 15 and the driving wheel 14, the cooperation accuracy between the driving wheel 14 and the driving wheel rubber ring 15 is ensured. The specific size of the pressure plate 1201 can be adjusted according to the driving wheel 14, the driving wheel rubber ring 15 or other structural sizes. The positioning block 1202 is located in the groove at the bottom end of the pressure plate 1201 and is connected by welding, as shown in Figure 7 and 8 As shown, the circumferential cooperation angle during the pressing is quantified and inspected through the scale line 120201, and the front and back sides of the driving wheel rubber ring 4 are prevented from being mistaken through the protruding part below the pressure plate 1201. The positioning hole 1203 can be designed in shape and accuracy according to specific size requirements, and the pressing accuracy is ensured and inspected through cooperation with the scale line 120201 on the positioning block 1202. The main disadvantage of the existing pressing tool is that personnel intervention is required throughout the pressing process, which is labor-intensive and slow.

[0007] Therefore, it is necessary to design a special vehicle pressing equipment capable of quickly switching auxiliary tooling, so that the assembly of the rubber ring is more convenient and convenient, effectively improves the installation efficiency, and reduces the installation difficulty of the rubber ring and the working intensity of the workers.

[0037] In order to make the purpose, content and advantages of the utility model more clear, the specific implementation manner of the utility model is further described in detail below in combination with the drawings and examples.

[0038] The embodiment proposes a special vehicle press fitting device capable of quickly switching auxiliary tooling, as shown in Figure 9 and 10 , the device mainly comprises a rubber ring press head 1, auxiliary tooling 3 or 5, a guide rod air cylinder 4, a rotary air cylinder 6, a hard limit 7, a magnetic coupling rodless air cylinder 8, a connecting piece 9, a rack 10 and a three-jaw air cylinder 11.

[0039] When the metal workpiece 12 (without the rubber ring installed on the drive wheel) moves to below the press 13, according to the model of the metal workpiece 12, the auxiliary tooling 3 or 5 of the corresponding model is rotated to the auxiliary tooling gripping position by the rotary cylinder 6. Figure 9 The auxiliary tooling 3 or 5 is positioned in the middle, and a hard limit 7 and a spring buffer are used to precisely position the rotation of the auxiliary tooling 3 or 5. The guide rod cylinder 4 drives the three-jaw cylinder 11 to descend through the connecting piece 9. The three-jaw cylinder 11 clamps the auxiliary tooling 3 or 5 by supporting it from the inside out. The guide rod cylinder 4 rises, and the magnetically coupled rodless cylinder 8 drives the guide rod cylinder 4 to move along the guide rail on the frame 10, moving the auxiliary tooling 3 or 5 directly above the metal workpiece 12. The guide rod cylinder 4 descends, lowers the auxiliary tooling, and positions it with the metal workpiece 12. The three-jaw cylinder 11 releases the auxiliary tooling, the guide rod cylinder 4 rises, and the magnetically coupled rodless cylinder 8 drives the guide rod cylinder 4 to move along the guide rail on the frame 10. Cylinder 4 retracts along the guide rail. The operator holds the rubber ring 2 and places it on the auxiliary fixture 3 or 5. The press 13 is started and pressed down. The rubber ring press head 1 presses down on the rubber ring 2 until the rubber ring 2 is pressed into place on the metal workpiece 12. The press 13 retracts, and the magnetic coupling rodless cylinder 8 drives the guide rod cylinder 4 to move directly above the metal workpiece 12. The three-jaw cylinder 11 clamps the auxiliary fixture, the guide rod cylinder 4 is raised, and the magnetic coupling rodless cylinder 8 drives the guide rod cylinder 4 to retract along the guide rail. The guide rod cylinder 4 descends and lowers the auxiliary fixture 3 or 5. Pressing is completed, and the product is ejected.

[0040] Among them, the auxiliary tooling 3 or 5 has a basically the same structure except for the size. Both are circular ring structures with trapezoidal cross sections. The upper end of the circular ring structure is chamfered, and the outer diameter of the upper end of the chamfer is smaller than the inner diameter of the rubber ring 2. The lower end of the circular ring structure is equipped with a positioning block, which can quickly align the angle of the rubber ring 2, making it convenient for the operator to directly put the rubber ring 2 in, avoiding problems such as the rubber ring not being able to be put in or taking too long to put in.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
