Description

Technical Field

[0001] The utility model relates to the technical field of nozzle processing, in particular to a fixture for drilling in nozzle processing. Background Technique

[0002] At present, the nozzle is a very crucial component in many kinds of equipment such as spraying, atomizing, oil spraying, sandblasting, spraying, etc., playing an important role. The nozzle is widely used in the industry, and its materials range from stainless steel, plastic to silicon carbide, polytetrafluoroethylene, PP (engineering plastic), aluminum alloy and tungsten steel, etc. Its application scope is generally commonly used in various industries such as automobiles, electroplating, surface treatment, high-pressure cleaning, dust removal, cooling, desulfurization, humidification, stirring, gardening, etc.

[0003] Among them, when processing the nozzle, it is necessary to drill the blank. During the processing, the nozzle is positioned in the fixture, and then the center of the nozzle is drilled through a drilling machine to complete the perforation of the nozzle, and then the next processing is carried out.

[0004] However, for the fixture for nozzle processing used in the market, the distance between the two groups of clamping blocks is relatively large. When in use, it is not easy to control whether the nozzle is positioned between the two groups of clamping blocks, and it is very easy to place the palm and the nozzle between the two groups of clamping blocks together, thus causing accidents. Therefore, it is necessary to design a new technical solution to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fixture for drilling in nozzle processing, which solves the problems put forward in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fixture for drilling in nozzle processing, including a driving box, an installation groove is opened inside the driving box, a positioning block is installed on one side inside the installation groove, and a positioning and clamping mechanism is installed inside the installation groove;

[0007] The positioning and clamping mechanism includes limiting sliding grooves opened on both sides of the installation groove, limiting sliders slidably installed at both ends of the two groups of limiting sliding grooves, extrusion blocks fixedly installed between adjacent two groups of limiting sliders, driving arms rotatably installed on the inner sides of the two groups of extrusion blocks, connecting seats rotatably installed at the other ends of the two groups of driving arms, and push arms fixedly installed on one side of the connecting seats.

[0008] As an optional solution of the technical solution of the present application, circular grooves are opened in the middle of one side of each of the extrusion block and the positioning block located on one side, and the two circular grooves correspond to each other, which can position the nozzle.

[0009] As an alternative solution of the technical solution of the present application, piston holes are provided at both ends of one side of the driving box. Piston rods are movably installed in the two piston holes. One side of the two piston rods is fixedly installed on the side wall of the positioning block, and a pressure sensor is fixedly installed on the side wall of the positioning block, which can detect the pressure of the positioning block.

[0010] As an alternative solution of the technical solution of the present application, springs are sleeved on the outer walls of the two piston rods. The two sides of the two springs are respectively fixedly installed on the side walls of the positioning block and the driving box, which can support the positioning block.

[0011] As an alternative solution of the technical solution of the present application, a mounting seat is fixedly installed on the side wall of the driving box. An electric push rod is fixedly installed in the middle of the side wall of the mounting seat. The other end of the electric push rod is fixedly installed with a push arm, which can push the push arm to move back and forth.

[0012] As an alternative solution of the technical solution of the present application, limiting grooves are provided on both sides of the mounting seat. Push plates are slidably installed in the two limiting grooves. The two sides of the push plate are respectively fixedly installed on the side walls of the electric push rod and the push arm, which can limit the push arm.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. After the nozzle is installed in the inner circular grooves of the positioning block and the extrusion block in the technical solution of the present application, the electric push rod is driven at the same time to push the push arm to move in the reverse direction, so that the two driving arms squeeze the two extrusion blocks and move synchronously to both sides of the installation groove, effectively clamping the nozzles in the two circular grooves. When adjusting the distance between the extrusion block and the positioning block, this device is firmly limited by the driving arm and the connecting seat, so that the reserved space in the two circular grooves is limited and the palm cannot be directly inserted into the circular groove, and the nozzle positioning is rapid, which greatly improves the safety when the operator uses it.

[0015] 2. In the technical solution of the present application, one side of the two piston rods is fixedly installed on the side wall of the positioning block, and a pressure sensor is fixedly installed on the side wall of the positioning block. When the operator drives the electric push rod to push the extrusion block, so that the extrusion block continuously squeezes the positioning block, after the pressure sensor installed on one side of the positioning block receives a fixed value of pressure, it will send a signal to the control processor to control the electric push rod to stop pushing the push arm, which can well detect whether the nozzle between the extrusion block and the positioning block is firmly clamped.

[0020] Please refer to Figure 1-2 , the present utility model provides a technical solution: a fixture for drilling in nozzle processing, including a driving box 1, an installation groove 11 is opened inside the driving box 1, a positioning block 12 is installed on one side inside the installation groove 11, and a positioning and clamping mechanism is installed inside the installation groove 11;

[0021] The positioning and clamping mechanism includes limiting chutes 2 opened on both sides of the installation groove 11, limiting sliders 21 slidably installed at both ends of the two groups of limiting chutes 2, extrusion blocks 22 fixedly installed between adjacent two groups of limiting sliders 21, driving arms 23 rotatably installed on the inner sides of the two groups of extrusion blocks 22, connecting seats 24 rotatably installed at the other ends of the two groups of driving arms 23, and pushing arms 25 fixedly installed on one side of the connecting seats 24. Circular grooves are opened in the middle of one side of one extrusion block 22 and the positioning block 12, and the two circular grooves correspond to each other, which can position the nozzle.

[0022] In this technical solution, after the nozzle is installed in the circular grooves on the inner sides of the positioning block 12 and the extrusion block 22, the electric push rod 41 is driven simultaneously to push the pushing arm 25 to move in the reverse direction, so that the two driving arms 23 squeeze the two extrusion blocks 22 and move synchronously to both sides of the installation groove 11, effectively clamping the nozzles in the two circular grooves. When adjusting the distance between the extrusion block 22 and the positioning block 12, this device is firmly limited by the driving arm 23 and the connecting seat 24, so that the reserved space in the two circular grooves is limited and the palm cannot be directly inserted into the circular grooves, and the nozzle positioning is rapid, ensuring the safety of the operator during use and greatly improving the safety.

[0023] In some technical solutions, piston holes 3 are opened at both ends of one side of the driving box 1, piston rods 31 are movably installed in the two groups of piston holes 3, one side of the two groups of piston rods 31 is fixedly installed on the side wall of the positioning block 12, and a pressure sensor 33 is fixedly installed on the side wall of the positioning block 12, which can detect the pressure of the positioning block 12.

[0024] In this technical solution, when the operator drives the electric push rod 41 to push the extrusion block 22, causing the extrusion block 22 to continuously extrude the positioning block 12, after the pressure sensor 33 installed on one side of the positioning block 12 receives a fixed value of pressure, it will transmit a signal to the control processor to control the electric push rod 41 to stop pushing the push arm 25, which can well detect whether the nozzle between the extrusion block 22 and the positioning block 12 is firmly clamped.

[0025] In some technical solutions, a mounting seat 4 is fixedly installed on the side wall of the driving box 1, and an electric push rod 41 is fixedly installed in the middle of the side wall of the mounting seat 4. The other end of the electric push rod 41 is fixedly installed with the push arm 25 and can push the push arm 25 to move back and forth. Limiting grooves 42 are opened on both sides of the mounting seat 4, and a push plate 43 is slidably installed in the two groups of limiting grooves 42. The two sides of the push plate 43 are respectively fixedly installed with the side walls of the electric push rod 41 and the push arm 25, which can limit the push arm 25.

[0026] In this technical solution, when the electric push rod 41 is driven to push the push arm 25, the push plate 43 in the limiting groove 42 can be used to limit the push arm 25 to ensure that the push arm 25 is pushed in the vertical direction.

[0027] In some technical solutions, springs 32 are sleeved on the outer walls of the two groups of piston rods 31, and the two sides of the two groups of springs 32 are respectively fixedly installed with the positioning block 12 and the side wall of the driving box 1, which can support the positioning block 12.

[0028] In this technical solution, when the two groups of extrusion blocks 22 move inward synchronously, the extrusion blocks 22 will move away from the positioning block 12, and the positioning block 12 will automatically reset due to the supporting force of the spring 32, which is convenient for detecting the pressure of the next group of nozzles.

[0029] When a tooling fixture for nozzle processing and drilling is in use, it should be noted that the present utility model is a tooling fixture for nozzle processing and drilling, and each component is a general standard component or a component known to those skilled in the art. Its structure and principle can be known by those skilled in the art through technical manuals or through conventional experimental methods.

[0030] During use, first operate the electric push rod 41 on the driving mounting base 4 to push the push arm 25 on the positioning and clamping mechanism to move outward. Synchronously, pull one end of the two driving arms 23 to move outward. The extrusion blocks 22 rotatably installed at the other ends of the two driving arms 23 will move inward following the driving arms 23, leaving enough space between the positioning block 12 and the extrusion blocks 22. After waiting for the nozzle to be installed in the inner circular grooves of the positioning block 12 and the extrusion blocks 22, simultaneously drive the electric push rod 41 to push the push arm 25 in the reverse direction, causing the two driving arms 23 to squeeze the two extrusion blocks 22 and move synchronously towards both sides of the installation groove 11, effectively clamping the nozzles in the two circular grooves. When adjusting the distance between the extrusion blocks 22 and the positioning block 12, this device is firmly limited by the driving arms 23 and the connecting seat 24, so that the reserved space in the two circular grooves is limited and the palm cannot be directly inserted into the circular grooves. Moreover, the nozzle positioning is rapid, ensuring greatly improved safety for the operator during use. At the same time, one side of the two piston rods 31 is fixedly installed on the side wall of the positioning block 12, and a pressure sensor 33 is fixedly installed on the side wall of the positioning block 12. When the operator drives the electric push rod 41 to push the extrusion block 22, causing the extrusion block 22 to continuously squeeze the positioning block 12, after the pressure sensor 33 installed on one side of the positioning block 12 receives a fixed value of pressure, it will transmit a signal to the control processor to control the electric push rod 41 to stop pushing the push arm 25, which can well detect whether the nozzle between the extrusion block 22 and the positioning block 12 is firmly clamped.
