Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, and specifically to a device for grinding the ends of pipes. Background Technology

[0002] During the processing and installation of metal pipes such as steel pipes and aluminum pipes, it is often necessary to grind their ends to remove burrs and oxide layers produced during cutting, or to perform beveling to facilitate welding.

Specifically, the clamping units of existing devices are mostly fixed or only finely adjustable, and their clamping spacing cannot be flexibly adjusted according to the length of the pipe. When clamping long pipes, because the distance between the two end support points is fixed, a large overhang is formed at the other end of the pipe. When subjected to the radial force of the grinding head during the grinding process, it is very easy to generate obvious vibration and shaking. This not only seriously affects the dimensional accuracy and surface finish of the grinding, but also poses safety hazards. Utility Model Content

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.

[0017] Please see Figure 1-3 As shown, a pipe grinding device according to an embodiment of the present invention includes a base 1, a pipe clamping mechanism provided on the top surface of the base 1, the pipe clamping mechanism including a first clamping unit 2 and a second clamping unit 20; the first clamping unit 2 is fixedly installed on the top surface of the base 1; the second clamping unit 20 is slidably disposed on the top surface of the base 1 through a positioning mechanism; the positioning mechanism is configured to adjust the distance between the first clamping unit 2 and the second clamping unit 20; a grinding mechanism 3 is provided on one side of the top surface of the base 1 located at the first clamping unit 2; the grinding mechanism 3 is connected to a driving mechanism, the driving mechanism being configured to drive the grinding mechanism 3 to reciprocate along the base 1.

[0018] In use, the adjustable-spacing double clamping unit structure effectively adapts to pipes of different lengths, ensuring the stability of long pipes during the grinding process; the independent grinding mechanism 3 and its drive system enable precise control of reciprocating grinding motion, improving grinding quality and efficiency.

[0019] Both the first clamping unit 2 and the second clamping unit 20 include a base 21 and a frame 22; the frame 22 is disposed on the top surface of the base 21; two side plates 23 are disposed on the left and right sides of the frame 22 respectively; an installation interval is formed between the two side plates 23 and the frame 22; two arc-shaped clamping plates 24 are disposed in front and behind each installation interval respectively.

[0020] When in use, the symmetrical frame structure 22 and the arc-shaped clamping plate 24 design provide a uniform clamping force distribution, avoid deformation of the pipe during the clamping process, and ensure accurate positioning of the pipe.

[0021] Each arc-shaped clamping plate 24 includes an upper clamping section 25, a middle hinge section 26, and a lower driving section 27. The arc-shaped clamping plate 24 is rotatably disposed within the installation area via the hinge section 26. Two clamping blocks 28 are detachably mounted on the clamping section 25. A first driving member 29 is connected between the driving sections 27 of the two corresponding arc-shaped clamping plates 24. The main body of the first driving member 29 is rotatably connected to the driving section 27 of one of the arc-shaped clamping plates 24. The output end of the first driving member 29 is rotatably connected to the driving section 27 of the other arc-shaped clamping plate 24.

[0022] During use, the segmented design of the arc-shaped clamping plate 24 and the connection method of the first driving component 29 enable the synchronous movement of the two arc-shaped clamping plates 24, ensuring the balance of clamping force; the design of the detachable clamping block 28 facilitates the replacement of worn parts and extends the service life of the device.

[0023] Multiple mounting slots 4 are provided at the center of the top of the frame 22; each mounting slot 4 is equipped with a support base 40; a support block 41 is fixedly installed on the top surface of the support base 40; a V-groove 42 is formed on the top surface of the support block 41; a first fastening hole 43 is provided on one side of the mounting slot 4; a number of second fastening holes 44 corresponding to the first fastening holes 43 are formed in an array at the mating ends of the support base 40 and the mounting slot 4.

[0024] During use, the support block 41 and its V-groove 42 structure provide stable intermediate support for the pipe, preventing the long pipe from sagging and deforming due to its own weight; the adjustable support seat 40 design allows the support position to be flexibly adjusted according to the outer diameter of the pipe.

[0025] The positioning mechanism includes a first guide rail 10 and a first slider 11; the first slider 11 is slidably engaged with the first guide rail 10; the second clamping unit 20 is fixedly installed on the top surface of the first slider 11; a locking knob 12 is also provided on the outer side of the first slider 11.

[0026] In use, the guide rail slider mechanism, combined with the design of the locking knob 12, enables the second clamping unit 20 to be quickly and accurately adjusted and reliably locked, making operation simple and positioning accurate.

[0027] The grinding mechanism 3 includes two second guide rails 30 disposed on the top surface of the base 1; each second guide rail 30 is equipped with a second slider 31; the top surface of the two second sliders 31 is provided with a sliding seat 32; the top surface of the sliding seat 32 is provided with a motor mounting seat 33; the motor mounting seat 33 is equipped with a drive motor 34; the output shaft of the drive motor 34 is connected to a grinding disc 35; the base 1 has an opening 36 at the corresponding position of the sliding seat 32; the sliding seat 32 has a connecting part 37 extending downward into the opening 36; an adjusting screw 38 adapted to the connecting part 37 is disposed below the base 1; the adjusting screw 38 is connected to a first driving device 39.

[0028] In use, the combination of the multi-stage guide rail system and the adjusting screw 38 mechanism enables precise motion control of the grinding mechanism 3 in three-dimensional space, ensuring the accuracy of the grinding position and the stability of the feed. The base 1 has two fixed ears located below the opening 36. The adjusting screw 38 is rotatably mounted between the two fixed ears via a bearing, and one end of the adjusting screw 38 is connected to the output shaft of the first drive device 39. The connecting part 37 has a threaded hole that engages with the adjusting screw 38. The first drive device 39 (preferably a servo motor) is fixed to the lower surface of the base 1 and drives the adjusting screw 38 to rotate through the first drive mechanism. The adjusting screw 38, through the engagement with the threaded hole and the engagement between the second guide rail 30 and the second slider 31, drives the grinding mechanism 3 to reach the predetermined position or return to the preparatory position. An infrared laser positioner is located on one side of the base 1 at the final grinding point of the grinding mechanism 3.

[0029] Two third guide rails 5 are correspondingly provided on the top surface of the sliding seat 32; each third guide rail 5 is equipped with a third slider 50; the motor mounting base 33 is fixedly installed on each third slider 50; a stand 51 is provided on one side of the top surface of the sliding seat 32; a second drive device 52 is installed on the stand 51; the output end of the second drive device 52 is drivenly connected to the motor mounting base 33.

[0030] During use, the third guide rail 5 and the second drive device 52 enable the reciprocating motion of the grinding disc 35, allowing for continuous grinding of the inner and outer arc surfaces of the pipe end simultaneously, significantly improving processing efficiency. "Non-long-term contact grinding" (i.e., intermittent contact grinding achieved by driving the grinding disc 35 to reciprocate through the second drive device 52) brings several significant benefits. Specifically, under high-speed grinding, continuous contact between the grinding wheel and the metal pipe generates a large amount of frictional heat. Intermittent contact provides a short cooling time for the pipe and the grinding wheel, effectively preventing heat accumulation. This avoids local annealing (reduction in hardness), burn marks, or thermal deformation of the pipe, thereby ensuring the original properties of the material and the surface quality of the grinding area.

[0031] The specific working process of this utility model is as follows: According to the length of the pipe to be ground, loosen the locking knob 12, slide the second clamping unit 20 along the first guide rail 10, adjust the distance between the two clamping units to a suitable position and then lock them; according to the outer diameter of the pipe, select a suitable position in the mounting slot 4 of the frame 22 to install the support block 41 and fix it with fasteners; place the pipe in the clamping unit, with the middle part of the pipe supported by the V-groove 42 of the support block 41, and the end of the pipe extending into the grinding area; start the first driving component 29 to drive the arc-shaped clamping plate 24 to rotate, and reliably clamp the pipe through the clamping block 28; turn on the infrared laser positioner and align the end of the pipe to be ground with the laser indication position; Start the first drive device 39, and drive the sliding seat 32 forward by adjusting the lead screw 38, so that the grinding disc 35 approaches the end of the pipe to the predetermined position; start the drive motor 34, and drive the grinding disc 35 to rotate at high speed; start the second drive device 52, and drive the motor 34 mounting base 33 to reciprocate along the third guide rail 5, so that the grinding disc 35 continuously grinds the end of the pipe; during the grinding process, the operator can adjust the grinding parameters in real time through the control panel (the control panel is set on the front side of the top of the base 1 to drive the operation of various electrical components), including feed speed, reciprocating frequency, etc.; after the grinding of one end is completed, exit the grinding mechanism 3, release the clamping unit, turn the pipe around and repeat the above process to grind the other end; after the grinding is completed, return the grinding mechanism 3 to the ready position and turn off all power.

[0032] Preferred implementation scheme: The infrared laser locator can be replaced with other types of visual positioning systems, such as laser rangefinders or CCD camera systems; the first drive component 29 and the second drive device 52 can adopt linear drive elements such as electric push rods, hydraulic cylinders or pneumatic cylinders; the control panel can be integrated with a PLC control system to realize automated control of the grinding process; the grinding disc 35 can be replaced with grinding tools of different materials and grit sizes according to processing requirements to adapt to different grinding process needs.
