DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0024] See also Figure 1-5 The present embodiment provides the following technical solution: a positioning device for preventing the valve housing from deflecting, comprising a placement table 1 and a valve housing body 2 arranged on the placement table 1, wherein the placement table 1 is provided with a plurality of fixing holes 7 for fixing the placement table 1 on the processing table of the punching equipment, and the placement table 1 can be fixed on the processing table of the punching equipment through the fixing holes 7, so as to facilitate the disassembly and assembly of the device.

[0025] The first positioning mechanism is used to position one end of the valve housing body 2. The first positioning mechanism includes a positioning platform 3 fixedly arranged on the placement platform 1 and a positioning cover 4 movably arranged above the positioning platform 3. The positioning platform 3 and the positioning cover 4 are adapted to the mounting cavity on the valve housing body 2. Through the positioning platform 3 and the positioning cover 4, after the mounting cavity of the valve housing body 1 is sleeved on the positioning platform 3, the positioning cover 4 can be placed in the valve body mounting cavity, and the positioning cover 4 is connected to the positioning platform 3 to cooperate with each other to position the front end of the valve housing body 1.

[0026] like Figure 5 As shown, the installation cavity is at the front end of the valve housing body 2, the diameter of the top end of the installation cavity is larger than that of the lower end of the installation cavity, the positioning platform 3 is adapted to the lower end of the installation cavity, the positioning cover 4 is adapted to the top end of the installation cavity, and the rear end between the positioning cover 4 and the positioning platform 3 is smaller than the thickness of the valve housing body 2, so that the positioning cover 4 and the positioning platform 3 can cooperate to press and fix the valve housing body 2.

[0027] The positioning platform 3 and the positioning cover 4 are connected by a first connecting member, which includes a first bolt 8, a first screw hole 9 provided on the positioning platform 3 and a first through hole 10 provided on the positioning cover 4. The first bolt 8 passes through the first through hole 10 and is threadedly connected with the first screw hole 9. Through the first bolt 8, the first screw hole 9 and the first through hole 10, the positioning cover 4 can be easily disassembled and assembled on the positioning platform 3, which is beneficial to the positioning and installation of the valve housing body 1.

[0028] The second positioning mechanism is used to position the other end of the valve casing body 2. The second positioning mechanism includes a positioning block 5 movably arranged on the placement table 1. The placement table 1 is provided with a moving groove 6 for the positioning block 5 to move, which is used to make the positioning block 5 slide closer to or away from the positioning table 3. Through the positioning block 5, while the positioning table 3 and the positioning cover 4 position the front end of the valve casing body 2, the positioning block 5 can slide closer to or away from the valve casing body 2, thereby avoiding the deflection of the valve casing body 2 during processing, thereby increasing the positioning effect of the valve casing body 1.

[0029] The positioning block 5 includes a movable plate 51 and a clamping plate 52. The clamping plate 52 is fixedly arranged at one end of the movable plate 51 opposite to the positioning platform 3. The movable plate 51 and the clamping plate 52 increase the stability of the positioning block 5 when positioning the valve housing body 2, and further increase the effect of positioning the valve housing body 2.

[0030] The bottom of the movable plate 51 is fixedly connected to the limiting block 11, and a limiting groove 12 adapted to the limiting block 11 is arranged in the movable groove 6. The limiting block 11 and the limiting groove 12 increase the stability of the movable plate 51 during movement, and further increase the stability of the positioning block 5 during movement.

[0031] In some embodiments, the movable plate 51 , the clamping plate 52 and the limiting block 11 are integrally arranged, thereby increasing the stability of the positioning block 5 .

[0032] The positioning block 5 is connected to the placement table 1 through a second connecting member, which includes a second bolt 13, a second screw hole 14 arranged on the limiting groove 12 and a second through hole 15 arranged on the positioning block 5. The second bolt 13 passes through the second through hole 15 and is threadedly connected with the second screw hole 14. The second bolt 13, the second screw hole 14 and the second through hole 15 facilitate the disassembly and assembly of the positioning block 5 on the placement table 1, thereby facilitating the removal and placement of the valve housing body 2.

[0033] The second through hole 15 is arranged along the length direction of the movable groove 6 , so that when the second bolt 13 is in a loose state, the position of the positioning block 5 can be adjusted, thereby facilitating the positioning of the valve housing body 2 .

[0034] The working principle of the utility model is as follows: firstly, the installation cavity on the valve housing body 2 is sleeved on the positioning platform 3, and then the positioning cover 4 is placed on the top of the installation cavity, and the first bolt 8 is threadedly connected to the inside of the first screw hole 9 through the first through hole 10, so that the positioning cover 4 and the positioning platform 3 cooperate to fix the front end of the valve housing body 2;

[0035] Then slide the positioning block 5 to move toward the positioning platform 3 until the positioning block 5 contacts the rear end of the valve housing body 2, and then fix the positioning block 5 on the placement platform 1 by tightening the second bolt 13, so that the positioning block 5 cooperates with the positioning platform 3 and the positioning cover 4 to complete the positioning operation of the valve housing body 2.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
