However, in order to achieve precise operation, the motor not only needs to be a servo motor, but also needs to be set with a matching control panel, which greatly increases the equipment cost of the fixture and is not conducive to its widespread use.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a jig for processing pump covers, comprising a jig table, wherein the jig table includes a base;

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 The present invention provides a technical solution: a jig for processing pump cover, including a jig table 1, the jig table 1 including a base 101;

[0027] An adjustment component 2 is provided on the top of the base 101. The adjustment component 2 includes a vertical shell 201. A first side groove 202 and a second side groove 203 are respectively opened on both sides of the vertical shell 201. A vertical rod 204 is fixedly connected inside the vertical shell 201. A lifting sleeve 205 is slidably sleeved on the outside of the vertical rod 204. The lifting sleeve 205 is also slidably connected to the first side groove 202. A connecting block 206 is fixedly connected to the top of the lifting sleeve 205. A sliding rod 207 slides through the middle of the connecting block 206. A friction pad 208 and a pull ring 209 are fixedly connected to both ends of the sliding rod 207. A first spring 210 is provided between the connecting block 206 and the pull ring 209.

[0028] The lifting sleeve 205 is rotatably connected to a rotating shaft 211 in the middle. The rotating shaft 211 passes through the first side groove 202 and the second side groove 203. A positioning ring 212 is fixedly connected to the outside of the rotating shaft 211. A rotating block 213 is symmetrically rotatably connected to one side of the lifting sleeve 205 located outside the vertical shell 201. A pressing strip 215 is fixedly connected to the side of the rotating block 213 near the positioning ring 212. A pinch plate 214 is fixedly connected to the other side of the rotating block 213. A second spring 216 is fixedly connected between the upper and lower pinch plates 214. A wear-resistant pad is provided at the sliding connection between the lifting sleeve 205 and the first side groove 202 to effectively reduce wear caused by long-term friction.

[0029] One end of the rotating shaft 211 is provided with a locking component 3.

[0030] The first spring 210 is sleeved on the outside of the sliding rod 207. One end of the first spring 210 is fixedly connected to the connecting block 206, and the other end of the first spring 210 is fixedly connected to the pull ring 209. The friction pad 208 is in contact with the outside of the vertical rod 204. The first spring 210 is a high-strength spring. The strong pulling force of the first spring 210 can ensure the squeezing force between the friction pad 208 and the vertical rod 204, thereby making the position of the lifting sleeve 205 automatically and stably locked.

[0031] The outer side of the positioning ring 212 is provided with friction texture, and the end of the extrusion strip 215 is attached to the outer side of the positioning ring 212. The end face of the extrusion strip 215 is provided with friction stripes. The friction stripes on the end face of the extrusion strip 215 adopt a cross pattern design to increase the friction coefficient. The two pinch plates 214 facilitate one-handed unlocking, while the second spring 216 will cause the extrusion strip 215 to return to its original position and be in contact with the positioning ring 212. The extremely high friction coefficient formed by the friction stripes and friction texture can prevent the positioning ring 212 and the extrusion strip 215 from slipping. Moreover, the two extrusion strips 215 are symmetrically and obliquely arranged to prevent the rotating shaft 211 from rotating arbitrarily in both directions.

[0032] The rotating shaft 211 passes through the first side groove 202 and the second side groove 203, and the first spring 210 and the sliding rod 207 both move within the second side groove 203.

[0033] The locking assembly 3 includes a fixed housing 301 fixed to one end of the rotating shaft 211. A double-ended screw 302 is rotatably connected inside the fixed housing 301, and a slide rod 303 is fixedly connected thereto. A threaded sleeve 304 is symmetrically threaded and slidably sleeved on the outside of the double-ended screw 302. A slide sleeve 305 is slidably sleeved on the outside of the slide rod 303. The threaded sleeve 304 is slidably connected to one side of the fixed housing 301. A clamping bar 306 is fixedly connected to one side of the threaded sleeve 304.

[0034] The sliding sleeve 305 is fixedly connected to the threaded sleeve 304.

[0035] The clamping bars 306 have a V-shaped groove on one side that is close to each other. A rubber pad 307 is fixedly connected in the V-shaped groove. One end of the double-headed screw 302 passes through the fixing shell 301 and is fixedly connected to the knob 308. The rubber pad 307 can prevent the pump cover from slipping.

[0036] Working principle: Before using this type of pump cover machining fixture, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, firstly, use a pry bar or your finger to pry or pull the pull ring 209 to make the sliding rod 207 slide, causing the friction pad 208 to disengage from the vertical rod 204, thereby allowing the sliding sleeve 205 to slide on the vertical rod 204, so that its height can be changed quickly to adapt to the operating habits of operators of different heights.

[0037] By squeezing the extrusion bar 215 with both hands, the rotating block 213 rotates, causing the extrusion bar 215 to move outward and disengage from the positioning ring 212. This allows the rotating shaft 211 to rotate rapidly with the fixed housing 301, which in turn allows the fixed housing 301 to rotate rapidly around the fixed pump cover. Ultimately, during the processing and inspection of the pump cover, it can be quickly rotated, flipped, and positioned without the need for component cooperation. This makes it more suitable for various working environments and eliminates the need for a control panel, thus reducing equipment costs.

[0038] Rotating the knob 308 causes the threaded sleeve 304 to move the clamping bar 306, thereby clamping the pump cover between the two rubber pads 307, thus enabling the fixation of pump covers of various sizes.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
