Description

Technical Field

[0001] The utility model relates to the technical field of plunger processing, in particular to a supporting device for plunger processing. Background Technique

[0002] A plunger is a mechanical component commonly used in pumps, engines, and other devices that require the conversion of linear motion into fluid power. The main function of the plunger is to push or extract fluid through its linear reciprocating motion. During the processing of the plunger, a supporting device is required, which can ensure that the plunger will not shift or deform due to external forces during processing, thus ensuring the processing accuracy and quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Please refer to Figures 1 - 5, A supporting device for plunger processing, including a plunger body 100 and a supporting mechanism 200 for clamping and positioning the plunger body 100. The bottom of the supporting mechanism 200 is fixedly connected with an installation mechanism 300:

[0025] Furthermore, the supporting mechanism 200 includes a supporting plate 201 arranged at the bottom of the plunger body 100. A placing groove 223 for carrying the plunger body 100 is opened at the center of the top of the supporting plate 201. A plurality of first clamping plates 220 are slidably connected to the top of the supporting plate 201 in a circumferential array. One end of the plurality of first clamping plates 220 close to the center of the supporting plate 201 abuts against the circumferential surface of the plunger body 100. The bottom of the supporting plate 201 is fixedly connected with a supporting shell 202. The center of the bottom inner wall of the supporting shell 202 is fixedly connected with a supporting column 203. The top of the supporting column 203 is fixedly connected with the bottom of the supporting plate 201.

[0026] The supporting plate 201 is located at the bottom of the plunger body 100 and has a placing groove 223 for placing the plunger body 100. The design of the placing groove 223 helps to initially position the plunger body 100. The first clamping plates 220 are distributed in a circumferential array around the supporting plate 201, can slide along the supporting plate 201, and can abut against the circumferential surface of the plunger body 100 to provide uniform clamping force. The installation mechanism 300 is installed at the bottom of the supporting mechanism 200 and is used to fix the entire supporting device on a machine tool or other processing equipment.

[0027] Furthermore, a first gear 204 is rotatably sleeved on the lower surface of the supporting column 203. A power gear 205 is meshed and connected to one side surface of the first gear 204. The bottom inner wall of the supporting shell 202 is fixedly connected with a power motor 206. The output end of the power motor 206 is fixedly connected with the inner wall of the power gear 205.

[0028] The supporting column 203 is located at the central position inside the supporting shell 202 and is fixedly connected with the supporting plate 201 at the top, playing a supporting role. After the power motor 206 is started, its output end drives the power gear 205 to rotate. Since the power gear 205 is meshed with the first gear 204, the rotation of the power gear 205 will be transmitted to the first gear 204.

[0029] Furthermore, a plurality of installation grooves 207 are opened on the surface of the supporting column 203 in a circumferential array. A limiting rod 208 is fixedly connected inside the plurality of installation grooves 207.

[0030] The limiting rod 208 is fixed inside the installation groove 207 to limit the movement path of the threaded sleeve 211 and ensure that the threaded sleeve 211 can only slide up and down along the limiting rod 208.

[0031] Further, a plurality of second gears 209 are meshed and connected to the surface of the first gear 204 in a circumferential array. A threaded rod 210 is fixedly connected to the inner walls of the plurality of second gears 209, and the tops of the plurality of threaded rods 210 are rotatably connected to the bottom of the support plate 201.

[0032] The power motor 206 transmits the rotational power to the first gear 204 through the power gear 205. When the first gear 204 rotates, it will drive the plurality of second gears 209 meshed with it to rotate simultaneously. Each second gear 209 is connected to the support plate 201 through the threaded rod 210. When the second gear 209 rotates, it will drive the threaded rod 210 to rotate.

[0033] Further, a threaded sleeve 211 is threadedly connected to the surfaces of the plurality of threaded rods 210. A limiting rod 208 is slidably connected to the inner wall of the threaded sleeve 211. A first spring 212 is movably sleeved on the surface of the limiting rod 208. The top of the first spring 212 is fixedly connected to the bottom of the threaded sleeve 211, and the other end of the first spring 212 is fixedly connected to the bottom of the inner wall of the installation groove 207.

[0034] The rotation of the second gear 209 will drive the threaded rod 210 to rotate, thereby realizing the up and down movement of the threaded sleeve 211 along the threaded rod 210. The design of the limiting rod 208 and the first spring 212 ensures the stable movement of the threaded sleeve 211 and prevents shaking or jamming during the processing.

[0035] Further, a fixed sleeve 213 is rotatably connected to one side of the threaded sleeve 211. A telescopic rod 214 is slidably connected to the inside of the fixed sleeve 213. One end of the telescopic rod 214 extends outside the fixed sleeve 213 and is rotatably connected to a moving block 216. A second spring 215 is fixedly connected between the fixed sleeve 213 and the telescopic rod 214.

[0036] The second spring 215 provides the restoring force for the telescopic rod 214 to ensure that the telescopic rod 214 can automatically reset when clamping is not required, so that the first clamping plate 220 returns to the initial position.

[0037] Further, the moving blocks 216 are arranged in a circumferential array on the top of the support plate 201. A plurality of moving grooves 217 are opened in a circumferential array on the top of the support plate 201. A guide rod 218 is fixedly connected to the inside of the plurality of moving grooves 217. The plurality of moving blocks 216 are slidably connected to the guide rod 218. A first clamping plate 220 is fixedly connected to the top of the moving block 216 near one side of the center of the support plate 201.

[0038] When the threaded sleeve 211 moves upward along the threaded rod 210, it will drive the telescopic rod 214 to expand and contract through the fixed sleeve 213. When the telescopic rod 214 extends, the moving block 216 moves inward along the guide rod 218, thereby driving the first clamping plate 220 to close. Through the design of the telescopic rod 214 and the second spring 215, the automatic clamping and releasing functions of the first clamping plate 220 can be realized, which can adapt to plungers of different specifications, increasing the flexibility of the equipment. At the same time, multiple first clamping plates 220 are arranged in a circumferential array, which can clamp the plunger evenly and provide better stability.

[0039] Further, a third spring 219 fixedly connected between the moving block 216 and the moving groove 217 is movably sleeved on the surface of the guide rod 218. A second clamping plate 221 is arranged above the first clamping plate 220. One side of the bottom of the second clamping plate 221 is fixedly connected with an electric push rod 222, and the bottom of the electric push rod 222 is fixedly connected with the top of the moving block 216.

[0040] The combined use of the first clamping plate 220 and the second clamping plate 221 can provide a stronger clamping force to ensure the stability of the plunger during the processing. Through the automatic control of the electric push rod 222, the precise adjustment of the second clamping plate 221 can be realized, improving the clamping accuracy and reliability, and can adapt to plungers of different sizes and shapes, increasing the flexibility of the equipment.

[0041] Further, the mounting mechanism 300 includes a mounting plate 301 fixedly arranged at the bottom of the support shell 202. Mounting bolts 302 for fixing the device are threadedly connected at the four corner positions of the mounting plate 301.

[0042] By tightening the mounting bolts 302 at the four corner positions of the mounting plate 301, the entire support device can be firmly fixed on the machine tool or the workbench. The design of the mounting plate 301 enables the user to conveniently install the support device at the required position and fasten it through the mounting bolts 302 to ensure the stability of the support device during the processing.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
