Description

Protective glove mounting structure of sand blasting machine

Technical Field

The utility model relates to a work piece surface treatment device, concretely relates to manual sand blasting machine, especially a mounting structure for sand blasting machine's protective gloves.

Background

The sand blasting machine is a device which utilizes compressed air to convey powdery particles, so that the particles moving at high speed scour the surface of an object to change the cleanliness and the roughness of the surface of a workpiece, and further change the mechanical property of the surface of the workpiece. The sand blasting machine requires that the working space is isolated and sealed from the outside in the working process, so that 2 protective gloves are usually required to be installed on the manual sand blasting machine, and an operator operates an internal workpiece through the protective gloves.

In the prior art, as shown in fig. 1 and fig. 2, 2 glove holes 6 are formed in a front panel of a sand blasting machine 1, a protective glove 3 is fixed on the front panel in a limiting manner by a fixing frame 2, and the frame is locked by 16M 6 bolts 4, so that the protective glove 3 is fixed to ensure sealing and prevent the protective glove 3 from falling off in an operation process.

Because the protection gloves receive the impact and easily take place the damage in the sandblast operation in-process, consequently often need change protection gloves, when full load operation, need carry out 4 changes usually weekly, change each time and all need demolish 16 bolts on the frame, take off protection gloves, install new protection gloves, 16 bolts of relocking, change the operation and need take about 30 minutes each time.

On the other hand, in the sand blasting operation process, the inner sand grains can also abrade the head of the bolt, and when the abrasion reaches a certain degree, the bolt is difficult to detach. Therefore, it is now necessary to replace the bolts with new bolts every week, resulting in an increase in production costs.

Disclosure of Invention

The invention aims to provide a protective glove mounting structure of a sand blasting machine, so as to realize the quick replacement and fixation of protective gloves.

In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows: the utility model provides a sand blasting machine's protective gloves mounting structure, is including installing the fixed frame around sand blasting machine panel glove hole, fixed frame is equipped with the profile modeling frame through a plurality of bolt locking on the sand blasting machine panel, the profile modeling frame the profile shape with the fixed frame cooperation, protective gloves cover are established fixed frame is last, the profile modeling frame card is established protective gloves outside and with protective gloves with the fixed frame card is fixed the position.

Among the above-mentioned technical scheme, fixed frame passes through bolt locking on sand blasting machine panel, and the protective gloves cover is established on fixed frame, and the profile modeling frame cover is in the well installed protective gloves of preventing, pushes away the profile modeling frame to with the fixed frame parallel and level, can lock protective gloves. Because the contour shapes of the profiling frame and the fixed frame are consistent, the sand can be fixed and sealed through the friction force between the protective gloves and the profiling frame, and the sand cannot leak.

In a preferred technical scheme, the clearance between the profiling frame and the fixing frame is 1.5 mm-2 mm.

According to the technical scheme, a jackscrew hole is formed in the profiling framework, an internal thread is arranged in the jackscrew hole, a jackscrew with an external thread is arranged in cooperation with the jackscrew hole, and the end of the jackscrew is in contact with a panel of the sand blasting machine. The design can facilitate the replacement of the protective gloves. When the protective gloves need to be replaced, the jackscrews are rotated to tightly jack the panel, the profiling frame is ejected out, and the protective gloves can be taken down.

According to a further technical scheme, the outer side of the profiling frame is provided with a decorative surface for covering protective gloves.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

1. the utility model changes the prior fixing of the protective gloves by the fixed frame and the bolt into the clamping and fixing of the profiling frame by arranging the profiling frame, so that the bolt is only used for positioning the fixed frame, and the bolt does not need to be disassembled when the protective gloves are replaced, and the replacement can be completed in 5 minutes after the test, which saves 25 minutes/time compared with the prior art and saves 100 minutes in a week;

2. the utility model is provided with the jackscrew hole on the profiling framework, and the profiling framework is easier to disassemble by matching with the jackscrew;

3. because the bolt is only used for positioning and fixing the frame and does not need to be frequently disassembled, the bolt can not influence the use even if the head of the bolt is worn, the bolt replacement period can be prolonged from 1 week to 1 year, and the bolt cost is saved.

Wherein: 1. a sand blasting machine; 2. a fixed frame; 3. protective gloves; 4. a bolt; 5. a profiling frame; 6. a glove hole; 7. a jackscrew hole; 8. and (5) jacking the screw.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

the first embodiment is as follows:

referring to fig. 3 and 4, in a protective glove mounting structure for a sand blasting machine, 2 glove holes are formed in a front panel of the sand blasting machine 1, fixing frames 2 are arranged around the corresponding glove holes, and the fixing frames 2 are respectively locked on the panel of the sand blasting machine through 8M 6 bolts 4.

The profiling frame 5 is arranged, the profile shape of the profiling frame 5 is the same as that of the fixed frame 2 and is slightly larger than that of the fixed frame 2, and a gap of 1.5 mm to 2 mm is formed between the profiling frame 5 and the fixed frame 2.

The outer side of the profiling frame is provided with a decorative surface for covering the protective gloves, the outline part of the profiling frame is connected with the decorative surface at an angle of 90 degrees, the outline part is sleeved on the periphery of the fixed frame, and the decorative surface covers the fixed frame and the protective gloves.

During installation, the protective gloves 3 are sleeved on the fixed frame 2, then the profiling frame 5 is clamped on the outer sides of the protective gloves 3, and the protective gloves 3 and the fixed frame 2 are clamped and fixed in position by utilizing friction force.

In the embodiment, the profiling frame 5 is provided with a jackscrew hole 7, the jackscrew hole 7 is provided with internal threads, a jackscrew 8 with external threads is arranged in cooperation with the jackscrew hole, and the end part of the jackscrew is in contact with a panel of the sand blasting machine. When the protective gloves need to be replaced, the jackscrews are rotated to jack the panel tightly, the profiling frame is ejected, and the protective gloves can be taken down. And then sleeving a new protective glove again and clamping and fixing the protective glove by using the profiling frame.
