Description

Technical Field

[0001] This utility model relates to the field of metal fittings sandblasting, and in particular to a sandblasting auxiliary fixture device. Background Technology

[0002] In the process of sandblasting hardware, existing auxiliary fixtures have obvious technical shortcomings: On the one hand, the hardware positioning structure is simple in design, mostly relying on a single slot or simple clamp for fixation. The impact force of the sand during sandblasting can easily cause the hardware to shift and shake, resulting in uneven sandblasting roughness and insufficient edge processing precision, affecting the consistency of product quality. On the other hand, the clamping distance of the fixture is fixed and cannot be flexibly adjusted according to the thickness of hardware of different specifications. When facing the processing needs of hardware with multiple thicknesses, it is necessary to frequently change special fixtures, which increases equipment procurement costs and prolongs process changeover time. In addition, after sandblasting, the hardware needs to be manually removed from the fixture and transferred to independent drying equipment for subsequent processing. During the transfer process, the surface of the hardware is easily scratched due to collisions, and the additional transfer steps and drying equipment occupy a lot of space, resulting in a cumbersome overall processing flow, long production cycle, significantly reduced processing efficiency, and difficulty in adapting to mass production scenarios. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a sandblasting auxiliary fixture device, which can stably clamp and sandblast the metal through multiple sets of fixtures. The fixture can be adjusted according to the metal of different thicknesses, and the drying operation can be carried out directly after sandblasting. It is very convenient to use.

[0004] This utility model is achieved using the following technical solution: a sandblasting auxiliary fixture device, comprising an upper template and a lower template for clamping fittings. The upper end face of the lower template has a plurality of fitting slots for placing fittings. The upper template has sandblasting nozzles corresponding to the fitting slots one by one. The bottom of the upper template is rotatably connected to a positioning pin via a bearing. The upper end of the lower template has a positioning groove adapted to the positioning pin, and the positioning pin and the positioning groove cooperate to guide and connect the upper template and the lower template. A positioning component for fixing the distance between the upper and lower templates is provided between the positioning pin and the positioning groove. A drying component for drying the sandblasted fittings is also integrated on the positioning pin.

[0005] Preferably, the positioning component includes a limiting block fixed to the outer side of the bottom of the positioning pin, a limiting groove formed on the edge of the positioning groove for vertical insertion of the limiting block, and a rotating groove formed on the inner wall of the positioning groove. The rotating groove is an annular structure and at least two sets are longitudinally spaced along the inner wall of the positioning groove. The limiting block can be selectively engaged in any set of rotating grooves to adjust the distance between the upper template and the lower template.

[0006] Preferably, the upper end of the positioning pin is movably connected to the upper template and then fixedly connected to a rotating block, and the contact surface between the rotating block and the positioning pin is also provided with a friction pad.

[0007] Preferably, the drying assembly includes a heat insulation groove located on the outside of the positioning pin near the upper end, a connection port and an air outlet located on the positioning pin and communicating with the heat insulation groove, and a heating wire installed inside the heat insulation groove. The connection port is used to connect to an external air source, and the gas heated by the heating wire can be ejected from the air outlet.

[0008] Preferably, several air outlets are evenly arranged along the circumference of the positioning pin, and each air outlet faces a different direction to ensure that the gas can flow evenly through the gap between the upper and lower templates.

[0009] Preferably, there are four sets of positioning pins and positioning grooves, which are respectively set at the four corners of the bottom of the upper template and the top of the lower template. Only two sets of positioning pins and positioning grooves distributed diagonally are equipped with the positioning components. The outer walls of the other two sets of positioning pins and the inner walls of the positioning grooves are smooth structures and only serve as guides.

[0010] Preferably, the outer walls of the upper and lower templates are fixedly connected with handles that facilitate opening and closing the templates, and the outer surface of the handles is provided with anti-slip texture to prevent the hands from slipping during operation.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) This utility model, through the initial guidance of the positioning pin and the positioning groove, combined with the snap-fit ​​structure of the limiting block, the limiting groove and multiple sets of rotating grooves, can ensure that there is no displacement after the upper and lower templates are closed, avoid the metal parts from shifting during sandblasting, and improve the sandblasting accuracy.

[0012] (2) This utility model has multiple sets of annular rotating grooves arranged longitudinally on the inner wall of the positioning groove, which can adjust the spacing between the upper and lower templates according to the thickness of the hardware, and can adapt to different specifications of hardware without changing the fixture, thus reducing equipment costs.

[0013] (3) The designed positioning pin integrated drying component does not require the hardware to be transferred after sandblasting. Only the template spacing needs to be adjusted again, and the hardware can be dried by heating gas flowing through the gap, which shortens the processing cycle and improves efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please combine Figure 1-5A sandblasting auxiliary fixture device is applicable to the surface sandblasting treatment of metal fittings 3. Its structural details and usage process are as follows: The upper template 1 and the lower template 2 are made of high-strength metal material, which has good impact resistance and wear resistance. The upper end face of the lower template 2 has multiple sets of fitting grooves 4 for placing the fittings 3 to be processed. The upper template 1 has sandblasting nozzles 5 at the positions corresponding to the fitting grooves 4 to ensure that the sand can accurately cover the surface of the fittings 3 during sandblasting. The bottom of the upper template 1 is fixed with four sets of positioning pins 6, and the upper end of the lower template 2 has four sets of positioning grooves 7. The positioning pins 6 and the positioning grooves 7 cooperate to achieve precise guiding and docking of the upper and lower templates. Among them, the two sets of positioning pins 6 and positioning grooves 7 distributed diagonally are equipped with positioning components 8. The positioning components 8 include a limiting block 801 fixed to the bottom of the positioning pin 6 and a limiting block 801 opened on the edge of the positioning groove 7. The positioning pin 6 has a groove 802 and a rotating groove 803 formed on the inner wall of the positioning groove 7. The outer end of the positioning pin 6 passes through the upper template 1 and is fixedly connected to the rotating block 602. The rotating block 602 can drive the corresponding positioning pin 6 to rotate. The contact surface between the upper template 1 and the positioning pin 6 is also provided with a rubber pad 601. The rubber pad 601 increases the friction. When the positioning pin 6 rotates, it requires a little force, but it can ensure the stability of the positioning pin 6 when it is stationary, and maintain the relative stability after the upper template 1 and the lower template 2 are connected. The positioning pin 6 can be rotated by rotating the rotating block 602, so that the limiting block 801 on its outer side is inserted along the limiting groove 802 and locked in the rotating groove 803, thereby fixing the distance between the upper template 1 and the lower template 2. The outer walls of the upper template 1 and the lower template 2 are fixed with handles 10. The surface of the handles 10 is provided with anti-slip texture, which makes it easy for the operator to open, close and move the upper template 1.

[0020] In addition, a drying component 9 is integrated on the positioning pin 6. The drying component 9 includes a heat insulation groove 901 opened on the outside of the positioning pin 6, a connection port 902 communicating with the heat insulation groove 901, an air outlet 903, and a heating wire 904 installed inside the heat insulation groove 901. The connection port 902 is used to connect to an external air source, and the heating wire 904 can heat the gas entering the heat insulation groove 901. The heated gas is sprayed out through the air outlet 903 into the gap between the upper template 1 and the lower template 2 to achieve the drying treatment of the fitting 3.

[0021] Based on the above structural design, this utility model is used as follows: S1. Place the entire fixture on the sandblasting workbench, lift the upper template 1 with handle 10 and place it on one side of the workbench; place the metal parts 3 to be sandblasted one by one into the metal parts slots 4 of the lower template 2, ensuring that the metal parts 3 are placed stably.

[0022] S2, grab the handle 10 to close the template 1, so that the four sets of positioning pins 6 are inserted into the positioning grooves 7 respectively. The limiting blocks 801 on the diagonally distributed positioning pins 6 slide down the limiting grooves 802 to the appropriate position. Then rotate the rotating block 602 so that the limiting blocks 801 are locked into the rotating grooves 803 of the corresponding height, thus completing the positioning and fixing of the upper template 1 and the lower template 2, and ensuring that the hardware 3 is stably clamped.

[0023] S3, push the fixture into the sandblasting equipment, turn on the sandblasting device, and perform sandblasting operation at the sandblasting nozzle 5 of the upper template 1 to ensure that the surface of the hardware 3 is evenly covered with sand.

[0024] S4. After sandblasting is completed, remove the fixture from the sandblasting equipment and adjust the positioning component 8 to increase the distance between the upper template 1 and the lower template 2. Connect the external air source through the connection port 902, turn on the heating wire 904, and the heated gas is sprayed out through the air outlet 903 and flows through the gap between the upper template 1 and the lower template 2 to dry the hardware 3.

[0025] S5, turn off the gas source and heating wire 904, lift the upper template 1, and take out the hardware 3 in the hardware slot 4; clean the sand material remaining on the surface of the upper template 1 and the lower template 2 to complete one processing cycle.

[0026] Based on this, it should be added that the heating wire 904 is controlled by an external switch and a display screen, and its heating temperature is monitored in real time. As someone skilled in the art, I will not go into the specific structural principles here.

[0027] Based on step S2, when installing fittings 3 of different specifications and thicknesses, corresponding matching rotating grooves 803 will be set. That is, in actual applications, the number of sets of rotating grooves 803 can be adjusted according to the specifications of fittings 3. All modifications, equivalent substitutions, etc. that do not depart from the principle and spirit of this utility model should be included within the protection scope of this utility model.

[0028] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
