Description

Technical Field

[0001] This utility model relates to the field of plastic parts machining technology, specifically to an auxiliary positioning frame for machining large plastic parts. Background Technology

[0002] Some plastic parts are only needed as single pieces, so they are generally not processed by mold making. They can be formed by machining to achieve the required shape. Small parts are usually fixed on the positioning table of the machine tool by positioning fixtures and then processed by the cutter shaft.

[0003] However, when processing some longer plastic parts, the parts are too long to be completely fixed on the machine tool, causing them to overflow onto both sides of the machine tool's positioning table. This results in poor stability of the plastic parts during milling and affects the processing quality. Utility Model Content

[0004] To address the problem that when machining long plastic parts, the parts cannot be fully fixed on the machine tool, resulting in poor stability during milling and affecting the quality of the machining, the purpose of this utility model is to provide an auxiliary positioning frame for machining large plastic parts.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an auxiliary positioning frame for machining large plastic parts, including a machine tool, a positioning table fixedly installed on the top surface of the machine tool, auxiliary devices installed on both sides of the positioning table, the auxiliary device including an auxiliary platform, a groove opened in the middle of the auxiliary platform, a bidirectional lead screw installed in the groove, two sliding sleeves symmetrically installed on the surface of the bidirectional lead screw, two positioning strips fixedly installed on the top surface of the two sliding sleeves, two positioning strips sliding relative to each other on the top surface of the auxiliary platform, a drive shaft fixedly installed at one end of the bidirectional lead screw, and a crank handle fixedly installed at one end of the drive shaft.

[0006] Preferably, positioning components are symmetrically installed on one side of the auxiliary platform, and the positioning components are slidably locked inside one side of the positioning platform. Fixing components are fixedly installed at both ends of the auxiliary platform on one side of the positioning components. The fixing components are threaded with positioning buckles, which pass through the fixing components and are threaded into the machine tool. A support frame is fixedly installed on the bottom surface of the auxiliary platform, and casters are installed at the four corners of the bottom surface of the support frame.

[0007] Preferably, the top surface of the auxiliary platform is provided with two sliding grooves on both sides of the groove. A guide rod is fixedly installed in each of the two sliding grooves. Guide sleeves are symmetrically installed on the bottom surface of the two positioning strips. The guide sleeves on the same side of the bottom surface of the two positioning strips slide relative to each other on the surface of a guide rod. A flexible pad is fixedly installed on one side of the positioning strip. The flexible pad cooperates with the positioning strip.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. In this utility model, two auxiliary devices are fixedly installed on both sides of the positioning table. The long plastic part to be processed is placed on the positioning table for positioning. The part of the long plastic part that extends beyond the positioning table is placed on the auxiliary table of the two auxiliary devices. After placement, the transmission shaft is controlled by the crank to drive the bidirectional lead screw to rotate. When the bidirectional lead screw rotates, it controls the two sliding sleeves to drive the corresponding positioning strips to move relative to each other, thus completing the clamping and positioning of the plastic part on the auxiliary table. This works in conjunction with the positioning table to complete the positioning work of the plastic part during processing, thereby improving the stability of the plastic part during milling.

[0010] 2. In this utility model, the auxiliary platform is installed and positioned on one side of the positioning platform by the positioning component. After positioning, the auxiliary platform is fixed on one side of the positioning platform with the cooperation of the corresponding positioning buckles of the two fixing components, thereby completing the installation and fixing of the auxiliary device on one side of the positioning platform. Similarly, the positioning buckles are removed from the fixing components, and with the cooperation of the moving wheels installed at the four corners of the bottom surface of the support frame, the auxiliary device is removed from one side of the positioning platform, completing the disassembly of the auxiliary device on one side of the positioning platform. The auxiliary device can be flexibly used according to the size of the plastic parts being processed. Attached Figure Description

Two sliding sleeves 23 are symmetrically installed on the surface of the bidirectional lead screw 22 and slide relative to each other on the surface of the bidirectional lead screw 22. Positioning strips 24 are fixedly installed on the top surface of the two sliding sleeves 23. There are two positioning strips 24 and they slide relative to each other on the top surface of the auxiliary table 21. A drive shaft 25 is fixedly installed at one end of the bidirectional lead screw 22, and a crank handle 251 is fixedly installed at one end of the drive shaft 25.

[0019] The positioning table 11 is installed and fixed by the machine tool 1. When a long plastic part needs to be processed, the two auxiliary devices 2 are installed and fixed on both sides of the positioning table 11. After the fixing is completed, the long plastic part to be processed is placed on the positioning table 11 for positioning. The part of the long plastic part that exceeds the positioning table 11 is placed on the auxiliary table 21 of the two auxiliary devices 2. After the placement is completed, the transmission shaft 25 is driven by the crank handle 251 to rotate the double-sided lead screw 22. When the double-sided lead screw 22 rotates, it controls the two sliding sleeves 23 to drive the corresponding positioning strips 24 to move relative to each other, thereby completing the clamping and positioning of the plastic part on the auxiliary table 21. The positioning of the plastic part on the auxiliary table 21 is completed by the two positioning strips 24.

[0020] A positioning element 213 is symmetrically installed on one side of the auxiliary table 21. The positioning element 213 is slidably locked inside one side of the positioning table 11. Fixing elements 214 are fixedly installed at both ends of the auxiliary table 21 on one side of the positioning element 213. A positioning buckle 215 is threaded into the fixing element 214 and threaded into the machine tool 1. A support frame 26 is fixedly installed on the bottom surface of the auxiliary table 21. Four casters 27 are installed at the four corners of the bottom surface of the support frame 26. With the cooperation of the casters 27 installed at the four corners of the bottom surface of the support frame 26, the auxiliary table 213 completes the auxiliary movement. The auxiliary platform 21 is installed and positioned on one side of the positioning platform 11. After positioning, with the cooperation of the positioning buckles 215 corresponding to the two fixing parts 214, the auxiliary platform 21 is fixed on one side of the positioning platform 11, thereby completing the installation and fixing of the auxiliary device 2 on one side of the positioning platform 11. Similarly, the positioning buckles 215 are removed from the fixing parts 214. With the cooperation of the moving wheels 27 installed at the four corners of the bottom surface of the support frame 26, the auxiliary device 2 is removed from one side of the positioning platform 11, completing the disassembly of the auxiliary device 2 on one side of the positioning platform 11. The auxiliary device 2 can be flexibly used according to the size of the plastic parts being processed.

[0021] The top surface of the auxiliary platform 21 is provided with two sliding grooves 212 on both sides of the groove 211. Guide rods 242 are fixedly installed in both sliding grooves 212. Guide sleeves 241 are symmetrically installed on the bottom surface of the two positioning bars 24. The guide sleeves 241 on the same side of the bottom surface of the two positioning bars 24 slide relative to each other on the surface of a guide rod 242. The two guide rods 242 are installed and fixed by the two sliding grooves 212 respectively. When the positioning bar 24 clamps and positions the plastic part to be positioned, the guide sleeves 241 installed on the bottom surface of the positioning bar 24 slide on the surface of the corresponding guide rod 242 as the positioning bar 24 moves, increasing the stability of the positioning bar 24 when it moves, and at the same time completing the guiding work of the positioning bar 24.

[0022] A flexible pad 243 is fixedly installed on one side of the positioning strip 24. The flexible pad 243 cooperates with the positioning strip 24. The flexible pad 243 installed on one side of the positioning strip 24 assists the positioning strip 24 in positioning and clamping the plastic part to be processed, preventing damage to the plastic part when the positioning strip 24 directly clamps the clamping surface of the plastic part. Positioning grooves 111 are symmetrically opened on both sides of the positioning table 11. The positioning component 213 is slidably locked in the positioning groove 111. The corresponding positioning component 213 is inserted and positioned by the positioning grooves 111 opened on both sides of the positioning table 11.

[0023] Two rotating parts 221 are fitted on both ends of the surface of the bidirectional lead screw 22. The two rotating parts 221 are fixedly installed on both sides of the groove 211. The bidirectional lead screw 22 is installed and positioned in the groove 211 by the two rotating parts 221, and at the same time, the bidirectional lead screw 22 is assisted to rotate in the groove 211. The bottom surface of the machine tool 1 is fixedly installed on both sides with evenly distributed support seats 12. The support seats 12 cooperate with the machine tool 1. The device is installed in the designated area for processing plastic parts by the cooperation of the support seats 12 and the machine tool 1.

[0024] Working principle: The positioning table 11 is installed and fixed by the machine tool 1. When a long plastic part needs to be processed, the two auxiliary devices 2 are installed and fixed on both sides of the positioning table 11. After the fixing is completed, the long plastic part to be processed is placed on the positioning table 11 for positioning. The part of the long plastic part that exceeds the positioning table 11 is placed on the auxiliary table 21 of the two auxiliary devices 2. After the placement is completed, the transmission shaft 25 is driven by the crank 251 to rotate the double-sided lead screw 22. When the double-sided lead screw 22 rotates, it controls the two sliding sleeves 23 to drive the corresponding positioning strips 24 to move relative to each other, thereby completing the clamping and positioning of the plastic part on the auxiliary table 21. The positioning of the plastic part on the auxiliary table 21 is completed by the two positioning strips 24.

[0025] With the cooperation of the movable wheels 27 installed at the four corners of the bottom surface of the support frame 26, the auxiliary platform 21 is installed and positioned on one side of the positioning platform 11 by the positioning component 213. After positioning, with the cooperation of the positioning buckles 215 corresponding to the two fixing components 214, the auxiliary platform 21 is fixed on one side of the positioning platform 11, thereby completing the installation and fixing of the auxiliary device 2 on one side of the positioning platform 11. Similarly, the positioning buckles 215 are removed from the fixing component 214, and with the cooperation of the movable wheels 27 installed at the four corners of the bottom surface of the support frame 26, the auxiliary device 2 is removed from one side of the positioning platform 11, completing the disassembly of the auxiliary device 2 on one side of the positioning platform 11. The auxiliary device 2 can be flexibly used according to the size of the plastic parts being processed.
