Description

TECHNICAL FIELD

[0001] The utility model relates to the field of heat tracing pipe processing, more specifically, it relates to a high-precision processing equipment for heat tracing pipe. BACKGROUND

[0002] In actual application scenarios, heat tracing pipes may need to be connected or matched with pipes and equipment in various directions, so drilling equipment is needed to drill holes at different angles to meet the functional requirements in complex systems. To achieve the drilling of heat tracing pipes at different angles, the clamping assembly used during drilling needs to be equipped with a driving device such as a motor to rotate the clamped heat tracing pipe, so that the heat tracing pipe fixed in the clamping assembly rotates according to the preset requirements, allowing the drill bit to drill at different angles of the heat tracing pipe to meet the requirements of the processing technology.

[0003] However, during actual drilling, a problem affecting drilling accuracy may occur. When the drill bit acts on the heat tracing pipe for drilling, friction between the drill bit and the heat tracing pipe will generate a certain force on the heat tracing pipe. At the same time, although the heat tracing pipe is fixed by the clamping assembly, it is not absolutely rigid and cannot completely rotate the heat tracing pipe, still having a certain space for movement (the heat tracing pipe is generally fixed by a gripper, and during design and manufacturing, the gripper and the heat tracing pipe must have a certain gap to ensure smooth gripping and release of the heat tracing pipe. Even when the heat tracing pipe is gripped, there is still a certain space for movement at the microscopic level). In this case, the frictional force exerted by the drill bit will easily cause the heat tracing pipe to rotate slightly, which will cause the originally intended drilling position of the drill bit to shift, affecting the accuracy of drilling and possibly resulting in inaccurate drilling, deviation in hole diameter, or rough hole wall, thereby affecting the processing quality and subsequent performance of the heat tracing pipe.

[0004] Therefore, to solve the above technical problems, the present application provides a high-precision processing equipment for heat tracing pipe. UTILITY MODEL CONTENT

[0022] like Figures 1-4 As shown, this utility model provides a high-precision processing equipment for heat tracing pipes, including a base 1 and a clamping assembly 2 located on the top of the base 1. An L-shaped support plate 3 is fixedly connected to the back of the base 1. A shifting device 4 for driving an electric drill bit 9 to move downward and laterally is installed at the bottom of the L-shaped support plate 3. A horizontal plate 5 is fixedly connected to the transmission part of the shifting device 4. The electric drill bit 9 is installed at the middle part of the bottom end of the shifting device 4. Elastic components 6 are installed on both sides of the bottom end of the horizontal plate 5. A pressing fixing block 7 is installed on the elastic support end of the elastic component 6. When the elastic component 6 is not squeezed, the pressing fixing block 7 is located below the electric drill bit 9.

[0023] The heat tracing pipe is clamped and rotated using clamping assembly 2. After being fixed, the optimal angle is found by rotating the pipe to drill holes. Once the angle is rotated to the appropriate position, the horizontal plate 5 is moved laterally to the appropriate position by the shifting device 4, and then the horizontal plate 5 is pressed down (the shifting device 4 consists of two parts: a horizontal moving device and a pressing and pushing device, which is installed on the rotating part of the horizontal moving device). The horizontal plate 5 drives the electric drill bit 9 to move downward (the electric drill bit 9 is turned on beforehand). The electric drill bit 9 can drill the clamped heat tracing pipe by moving downward. When the horizontal plate 5 drives the electric drill bit 9 to move downward, the pressing and fixing block 7, being below the electric drill bit 9, will first contact the heat tracing pipe, thereby compressing the elastic component 6 and forming a certain rebound force. This causes the pressing and fixing block 7 to exert a downward force on the heat tracing pipe, thereby further fixing the heat tracing pipe. The further the horizontal plate 5 drives the electric drill bit 9 to move downward, the higher the degree of compression of the elastic component 6 and the greater the rebound force, resulting in a better fixing effect of the pressing and fixing block 7 on the heat tracing pipe. This effectively prevents the heat tracing pipe from rotating slightly under force during drilling, thereby improving the processing accuracy.

[0024] Furthermore, the bottom of the pressure fixing block 7 is designed as an arc shape corresponding to the heat tracing pipe, so that it can fit snugly against the outer wall of the heat tracing pipe and securely fix it.

[0025] The specific structure of the spring 603 assembly is as follows: the elastic assembly 6 comprises hollow shells 601 fixed at the bottom ends of the two sides of the horizontal plate 5, the inner plates 602 movably connected inside the hollow shells 601, the springs 603 installed between the top ends of the inner plates 602 and the inner top walls of the hollow shells 601, the vertical rods 604 fixedly connected to the bottom ends of the inner plates 602 and penetrating out of the bottom of the hollow shell 601, the bottom ends of the vertical rods 604 fixed to the downward pressing fixed blocks 7, the guide rails A 605 fixedly connected to the two sides of the inside of the hollow shells 601, and the inner plates 602 slidably connected in the guide rails A 605 through the sliding blocks A 606.

[0026] That is, when the horizontal plate 5 moves downward, the downward pressing fixed blocks 7 first contact the heat tracing pipes clamped by the clamping assembly 2, the downward pressing fixed blocks 7 drive the inner plates 602 to move upward along the inside of the hollow shells 601 through the vertical rods 604, the inner plates 602 drive the sliding blocks A 606 to move upward, the sliding blocks A 606 slide upward along the guide rails A 605 to maintain the linear movement of the inner plates 602, and meanwhile, the springs 603 between the inner plates 602 and the inner top walls of the hollow shells 601 are compressed, the springs 603 generate a certain rebound force when compressed, the downward pressing fixed blocks 7 generate a downward pressing force on the heat tracing pipes, and thus the heat tracing pipes are fixed, with the further downward movement of the horizontal plate 5, the springs 603 are further compressed, and the rebound force generated is larger, so that the fixing effect of the downward pressing fixed blocks 7 on the heat tracing pipes is better.

[0027] The specific structure of the clamping assembly 2 is also given, which comprises a rotary driving device 201 installed on one side of the top end of the base 1 and a bearing seat 202 installed on the other side of the top end of the base 1, the bearing seat 202 is internally provided with a bearing 203, the inner ring part of the bearing 203 is fixedly connected with a rotating rod 204, and the head of the rotating rod 204 and the transmission end of the rotary driving device 201 are both provided with an electric gripper 205.

[0028] The two ends of the heat tracing pipe are clamped and fixed by the grippers on the rotary driving device 201 and the rotating rod 204, after being fixed, the heat tracing pipe is rotated by the rotary driving device 201, the heat tracing pipe drives the rotating rod 204 to rotate, the rotating rod 204 drives the inner ring of the bearing 203 to rotate, and the inner ring rotates along the outer ring, so as to rotate and support the other end of the heat tracing pipe.

[0029] In addition, the moving and fixing structure 8 is arranged between the bearing seat 202, the rotary driving device 201 and the base 1, the positions of the bearing seat 202 and the rotary driving device 201 can be moved and then fixed, the distance between the bearing seat 202 and the rotary driving device 201 can be flexibly adjusted through the moving and fixing structure 8, so as to adapt to the clamping of heat tracing pipes with different lengths.

[0030] The specific structure of the mobile fixing structure 8 is as follows: the mobile fixing structure 8 comprises a guide rail B801 fixed at the top end of the base 1, and a sliding block B802 fixed at the bottom end of the bearing seat 202 and the rotary driving device 201 and sliding along the guide rail B801; the top end of the base 1 is provided with transversely arranged screw holes 803 at both sides of the guide rail B801; and the sliding block B802 is fixedly connected with L-shaped connecting plates 804 provided with through holes 805.

[0031] That is, the bearing seat 202 or the rotary driving device 201 is pulled to move back and forth, and the two will drive the respective sliding blocks B802 to slide along the guide rail B801, and the sliding block B802 drives the movement of the L-shaped connecting plates 804 at both sides; after the bearing seat 202 or the rotary driving device 201 is moved to a suitable position, the screw is screwed through the through hole 805 on the L-shaped connecting plate 804 and then is screwed into the screw hole 803 at the corresponding position of the base 1 in a clockwise direction, so that the positions of the two are fixed.
