Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a fixture for processing nozzles. Background Technology

[0002] A nozzle is a device used to spray liquids or gases. It typically consists of a nozzle, a housing, and connecting parts. Based on the spraying method, nozzles are classified as direct-jet nozzles, diffuser nozzles, and rotary nozzles. The working principle of a nozzle is mainly based on the pressure difference used to propel liquids or gases. When liquids or gases pass through the nozzle of the nozzle under pressure, the special shape and size of the nozzle increase the fluid velocity and decrease the pressure, thus creating a spraying effect. During manufacturing, nozzles require clamps to hold them in place.

[0003] The nozzle is usually cylindrical. When existing clamps hold and fix it, they usually use V-shaped clamps to fit the surface of the nozzle. However, when clamping the nozzle, the different sizes of the nozzles result in different heights of the nozzle axis after clamping, which makes it inconvenient to process the nozzle. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for processing nozzles and spray heads, which has the advantage of coaxial clamping and solves the problem that the axial height of the current fixture is different after clamping nozzles and spray heads of different sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for processing nozzles and spray heads, comprising a housing, wherein a pushing mechanism and two limiting mechanisms are installed inside the housing, the pushing mechanism is located in the middle of the housing, and the two limiting mechanisms are symmetrically arranged about the pushing mechanism, two first limiting posts are symmetrically installed at the top of the housing, and two second limiting posts are installed in the middle of the housing, the pushing mechanism includes a slider, the top of the slider has a short plate, the bottom of the slider has a movable plate, the top of the short plate has a first clamping part, each limiting mechanism includes a rotating shaft, the top of the rotating shaft has a first arc plate bent toward the pushing mechanism, the bottom of the rotating shaft has a second arc plate bent toward the pushing mechanism, and the end of the first arc plate has a second clamping part.

[0006] Preferably, the first limiting post is placed at the top of both sides of the short plate, and the second limiting post is placed at the top of both sides of the movable plate.

[0007] Preferably, the vertical cross-section of the slider is trapezoidal, with the trapezoidal cross-section being narrower at the top and wider at the bottom.

[0008] Preferably, the movable plate has a through groove, and a rack is installed on one side of the through groove, the rack engaging with a drive mechanism.

[0009] Preferably, the rotating shaft, the first arc plate, and the second arc plate together form a C-shaped plate structure, wherein a roller that abuts against the inclined side of the slider is rotatably connected to the second arc plate, and a spring is installed at the end of the second arc plate near the roller, and the spring is in a compressed state.

[0010] Preferably, the driving mechanism includes a long rod, one end of which is rotatably connected to the inner wall of the housing, and the other end extends out of the side of the housing and is provided with a gripping part, and a gear that meshes with a rack is installed in the middle of the long rod.

[0011] Preferably, a lifting eye bolt is spirally connected to the side of the housing, and one end of the lifting eye bolt passes through the side of the housing and abuts against the side of the pushing mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a slider, a short plate, a first clamping part, a rotating shaft, a first arc plate, a second clamping part, a second arc plate, and rollers, allows the slider to move upward, and the rollers abutting the inclined side of the slider drive the second arc plate to rotate around the rotating shaft, while simultaneously driving the first arc plate to rotate synchronously. The nozzle is clamped by the rising second clamping part and the synchronous movement of the two second clamping parts. It can clamp nozzles of different sizes, and the nozzle axis of the clamped nozzle is in the same position.

[0014] 2. This utility model uses a movable plate, rack, long rod, grip, gear, and eye bolt. The grip drives the long rod to rotate, and the gear meshes with the rack to move the movable plate upward. The eye bolt abuts against the side of the pushing mechanism to fix the pushing mechanism. Loosening the eye bolt allows the spring to push the roller to quickly lower the pushing mechanism, enabling quick installation and removal of the nozzle. Attached Figure Description
