Problems solved by technology

The traditional portable ultrasonic impact gun has good mobility and flexibility when dealing with emergencies on the spot, but due to the manual hand-held operation of the portable ultrasonic impact gun, the stability is poor, the technical requirements for workers are high, and it cannot meet the requirements of mass processing.
Ultrasonic impact special treatment machine tool has the advantages of high precision, good stability and high efficiency, but it is expensive, maintenance costs are high, and it needs to be installed on an independent site, and the cost of use is high

Embodiment 1

[0030] See Figure 1 to Figure 13 , The support device has a ball screw mechanism 2, a sliding seat 3, a guide rod front frame 4, two guide rods 6, a support base 7 and a guide rod rear frame 10.

[0031] The ball screw mechanism 2 includes a ball screw 2-1 whose axial movement is hindered and a nut 2-2 threaded on the ball screw 2-1, and an operating handle 1 is connected to the front end of the screw 2-1. Described sliding seat 3 is made up of main body 3-1 and the nut seat 3-2 that is connected on the bottom front side of main body 3-1 with screw. The rear side of the bottom surface of the main body 3-1 is provided with a dovetail groove 3-1-a. The nut seat 3-2 is provided with a forward and backward through hole 3-2-a, and the nut seat 3-2 is sleeved on the nut 2-2 through the through hole 3-2-a, and tightly fits with the nut 2-2. When the ball screw 2-1 rotates, the nut 2-2 drives the sliding seat 3 to move on the ball screw 2-1 through the nut seat 3-2, and the sliding...

Embodiment 2

[0039] The support device adopts the anti-vibration rubber pad 13 on the inner wall of the lower seat 7-2 of the support seat 7 and the upper cover 7-1. All the other are identical with embodiment 1. The gun body of the portable ultrasonic impact gun is placed in the positioning hole 7-a of the support seat 7 of the supporting device, and the gun body is wrapped by the anti-vibration rubber pad on the positioning hole, so no rubber ring is needed.

Abstract

The invention provides a supporting device and a portable ultrasonic impact gun provided with the same. The supporting device is provided with a ball screw mechanism and a sliding seat driven by the ball screw mechanism to slide. A guide rod front bracket and a guide rod rear bracket are fixed to the sliding seat. A pair of guide rods is connected between the lower portion of the guide rod front bracket and the guide rod rear bracket. The two guide rods both support an adjusting seat. A supporting seat is fixed to the adjusting seat. A front-back locating hole matched with the corresponding position of a gun body is formed in the supporting seat. A pair of buffer springs is arranged between the upper portion of the guide rod front bracket and the supporting seat. The front ends of the two buffer springs are inserted into corresponding adjusting holes in the guide rod front bracket correspondingly. A fine adjustment bolt used for pushing the corresponding buffer spring is arranged in each adjusting hole. According to the portable ultrasonic impact gun, the middle portion of the gun body is arranged in the locating hole of the supporting seat to be fixed; impact abrasion between the gun body and the supporting seat can be reduced through rubber rings or rubber gaskets; reciprocating impact vibration can be effectively buffered through the buffer springs; and accordingly, the operational stability is improved.

Description

technical field [0001] The invention relates to a support device and a portable ultrasonic impact gun with the support device. Background technique [0002] Ultrasonic impact technology is an efficient method to eliminate harmful residual tensile stress on the surface of components or weld area, and introduce beneficial compressive stress, which has been applied in various fields. For example, in the rail transit transmission system, the shaft is usually designed as a gear shaft with teeth, and the gear shaft must often have a circumferential oil groove and a radial oil injection hole drilled at the bottom of the groove. The gear shaft oil groove orifice of this structure must be For surface strengthening treatment, ultrasonic shock treatment is generally used. The traditional portable ultrasonic impact gun has good mobility and flexibility when dealing with emergencies on site, but due to the manual hand-held operation of the portable ultrasonic impact gun, the stability i...
