[0002] The guide sleeve is mainly used as a spare part of a high-voltage line vacuum switch tube. In a hydraulic cylinder, the guide sleeve plays a role in supporting and ensuring the coaxiality of the piston rod and the cylinder barrel. Since the blank part of the guide sleeve has many burrs and is not flat enough after forming, it is necessary to further process the guide sleeve, perform chamfering treatment to remove the burrs, and make the edge of the guide sleeve smoother. The chamfering process is usually completed on a chamfering machine. This solution specifically relates to a chamfering device for a guide sleeve. When the existing chamfering device for a guide sleeve is in use, the model specifications of the clamping tooling for fixing the guide sleeve are fixed and inconvenient. When chamfering guide sleeves with different diameters, it is necessary to replace the clamping tooling with corresponding model specifications. And after installing the new clamping tooling, it is necessary to debug the clamping tooling to ensure that after clamping and fixing the guide sleeve, the center of the guide sleeve is directly opposite to the chamfering tool. Otherwise, processing deviation will occur, so it is not convenient enough. Content of the Utility Model

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figures 1 - 5 shown, a chamfering device for a guide sleeve includes a bottom box 1, a control box 2 is fixedly installed on one side of the front surface of the bottom box 1, a machine box 3 is arranged on one side of the top end of the bottom box 1, a motor 4 is fixedly installed in the middle of both sides of the machine box 3, propulsion cylinders 5 are fixedly installed on both sides of the machine box 3 and in front of and behind the motor 4, a tool chuck 7 is fixedly installed at the end of the output shaft of the motor 4, a fixing block 6 is fixedly installed at the end of the piston rod of the propulsion cylinder 5, a clamping assembly 8 is installed on the top end of the bottom box 1 and on one side close to the control box 2, and a waste slot 10 is arranged through the back surface of the bottom box 1 and on one side;

[0023] The clamping assembly 8 includes a carrying sleeve 801, three clamping cylinders 802 are fixedly installed inside the carrying sleeve 801, a clamping plate 803 is fixedly installed at the end of the piston rod of the clamping cylinder 802, and a positioning assembly 9 is installed on one side of the carrying sleeve 801 away from the tool chuck 7.

[0024] The positioning assembly 9 includes a bracket 901, a positioning laser pen 902 is fixedly installed at the end of the bracket 901, clamping bolts 903 are arranged through both sides of the bracket 901 and at one end away from the positioning laser pen 902, and an isolation ring 904 is arranged on the outer circle of the clamping bolt 903. By setting the positioning assembly 9, it is convenient to position the center of the guide sleeve so that the center of the guide sleeve and the center of the tool chuck are on the same straight line.

[0025] The fixing block 6 is fixedly connected to the bottom box 1 through bolts. Two sliding grooves are opened through the top surface of the bottom box 1, and the machine box 3 is slidably connected to the bottom box 1 through the sliding grooves. After the propulsion cylinder 5 is started, it drives the machine box 3 to slide towards the direction of the fixing block 6, and then drives the tool chuck 7 to move towards the direction of the carrying sleeve 801.

[0026] The waste chute 10 is located directly below the end of the tool chuck 7, and the waste chute 10 is sleeved with the bottom box 1. When the chamfering device is started to chamfer the guide sleeve, the generated waste falls into the waste chute 10, which is convenient for collecting the waste.

[0027] The carrier sleeve 801 is fixedly connected to the bottom box 1 by bolts. The included angle between two adjacent clamping cylinders 802 is 120°. The surface of the clamping plate 803 opposite to the clamping cylinder 802 is arc-shaped. When the clamping cylinder 802 is started, it drives the clamping plate 803 to move to clamp and fix the guide sleeve.

[0028] The isolation ring 904 is fixedly connected to the carrier sleeve 801. The clamping bolts 903 are sleeved between the support 901 and the isolation ring 904. The clamping bolts 903 are threadedly connected to the carrier sleeve 801. After tightening the clamping bolts 903, the support 901 is clamped by cooperating with the isolation ring 904, which is convenient for fixing the support 901. At the same time, the isolation ring 904 is used to prevent the support 901 and the positioning laser pen 902 from directly contacting the side surface of the carrier sleeve 801. When the support 901 is rotated, friction occurs between the positioning laser pen 902 and the carrier sleeve 801.

[0029] The inner side surface of the carrier sleeve 801 is arc-shaped, and the center of the carrier sleeve 801 and the center of the tool chuck 7 are on the same straight line. When the support 901 is rotated to a position perpendicular to the bottom box 1, the center of the positioning laser pen 902 and the center of the carrier sleeve 801 are on the same straight line. After installing the chamfering tool on the tool chuck 7, the support 901 is rotated to a position perpendicular to the bottom box 1, the guide sleeve is placed on the lower clamping plate 803, the clamping cylinder 802 is started to drive the clamping plate 803 to rise, so that the center of the guide sleeve coincides with the laser ray emitted by the positioning laser pen 902, and then the other two clamping cylinders 802 are started to drive the clamping plate 803 to clamp and fix the guide sleeve.

[0030] It should be noted that the present utility model is a chamfering device for a guide sleeve. When in use, first, according to the chamfering requirements of the guide sleeve, a suitable chamfering tool is installed on the tool chuck 7. Then, the clamping bolts 903 are loosened, and the support 901 is rotated to a position perpendicular to the bottom box 1. The clamping bolts 903 are tightened to clamp and fix the support 901 by cooperating with the isolation ring 904. Then, the positioning laser pen 902 is started to emit a laser ray through the control box 2;

[0031] After the positioning laser pointer 902 is turned on, place the guide sleeve to be chamfered on the clamping plate 803 located below, and then start the clamping cylinder 802 connected thereto through the control box 2 to drive the clamping plate 803 and the guide sleeve to rise synchronously. When the center position of the guide sleeve rises to the position of the laser ray emitted by the positioning laser pointer 902, turn off the clamping cylinder 802 located below, and start the other two clamping cylinders 802 to drive the other two clamping plates 803 to clamp and fix the guide sleeve.

[0032] After the guide sleeve is fixed, start the motor 4 and the propulsion cylinder 5. The propulsion cylinder 5 pulls the chassis 3 in the direction of the fixed block 6, and at the same time, the motor 4 drives the tool holder 7 to rotate. The two work together to drive the chamfering cutter to rotate and approach the guide sleeve at the same time, chamfering the guide sleeve. The waste generated during the chamfering process falls into the waste chute 10 and is collected, which is convenient for collecting and cleaning the waste.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
