Description

Technical Field

[0001] The utility model relates to the field of round tube processing equipment, in particular to a positioning device for processing round tubes. Background Art

[0002] Nowadays, round tubes play an increasingly important role in mechanical equipment parts, and they play many important roles such as connection and transmission. For example, they can be used in pipelines, thermal equipment, mechanical industry, petroleum geological drilling, containers, chemical industry and special purposes. The increasingly wide application has led to the need for round tubes to be connected with various parts during use. For example, machining operations such as chamfering the two ends of the round tube or tapping (i.e., tapping) one end of the round tube to facilitate the connection of various shapes of round tubes. Therefore, a positioning device is needed to fix the round tube during the processing.

[0003] The positioning device in the prior art solution is not able to fix round tubes of different diameters at the same time due to its relatively simple structure, which results in limitations in the use of the positioning device, thus affecting the processing efficiency of the round tubes. Utility Model Content

[0004] The embodiment of the present application provides a positioning device for processing round tubes, thereby solving the technical problem that the positioning device in the prior art solution cannot fix round tubes of different diameters at the same time due to its relatively simple structure, which leads to limitations in the use of the positioning device and affects the efficiency of round tube processing.

[0005] The technical solution adopted in the embodiment of the present application is as follows:

[0006] A positioning device for processing round tubes, comprising a base plate, a first arc plate for supporting the round tube, a second arc plate for fixing the round tube, a buffer device for buffering the second arc plate, a clamping device for clamping the second arc plate, a slideway for limiting the first arc plate and a first fixing member for fixing the first arc plate; two groups of symmetrically placed slideways are arranged on the base plate; the first arc plate and the second arc plate are both slidably connected to the two groups of slideways; the buffer device is arranged between the first arc plate and the second arc plate; the clamping device is arranged on the slideway; a plurality of groups of circular through holes arranged in a linear array are opened on the slideway; the first fixing member is connected to the first arc plate through the circular through holes.

[0007] A further technical solution is: the buffer device includes a spring for buffering the second arc plate and a telescopic rod for limiting the spring; the spring is arranged around the telescopic rod; the telescopic end of the telescopic rod is connected to the second arc plate, and the other end is connected to the first arc plate.

[0008] A further technical solution is: the clamping device includes a bending plate, a second fixing member for fixing the bending plate, and a threaded rod for clamping the second arc-shaped plate; the second fixing member is connected to the bending plate and the slide; the threaded rod is threadedly connected to the bending plate, and the end of the threaded rod rests on the second arc-shaped plate; a threaded handle is provided on the threaded rod.

[0009] A further technical solution is that rubber pads are provided on both the first arc plate and the second arc plate.

[0010] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0011] 1. Due to the use of the bottom plate, the first curved plate, the second curved plate, the buffer device, the clamping device, the slideway and the first fixing member, when the round tube needs to be fixed, the staff first places the round tube on the curved groove on the first curved plate, and then rotates the two sets of clamping devices at the same time, so that the two sets of clamping devices are pressed against the second curved plate at the same time, and push the second curved plate to slide along the slideway toward the first curved plate. When the curved groove on the second curved plate is firmly pressed against the top of the round tube, the round tube can be fixed at this time. When the clamping device pushes the second curved plate to slide along the slideway toward the first curved plate, the buffer device will be subjected to the pressure of the second curved plate, so that the buffer device can produce a buffering effect on the sliding process of the first curved plate, and then the second curved plate can be more stable in the process of fixing the round tube. Since the spacing between the first curved plate and the second curved plate can be adjusted through the mutual cooperation of the clamping device and the buffer device, the round tubes of different calibers can be fixed between the first curved plate and the second curved plate. Since both sets of slides are provided with a plurality of groups of circular through holes arranged in a linear array, and the two sets of first fixing members respectively pass through the corresponding circular through holes and are threadedly connected to the two ends of the first arc plate, the height of the first arc plate can be adjusted by adjusting the position of the first arc plate on the two sets of slides and fixing it through the two sets of first fixing members, thereby greatly increasing the practicality of the positioning device.

[0012] 2. Due to the use of the spring, when the clamping device pushes the second curved plate to slide along the slideway toward the first curved plate, the second curved plate will compress the spring, and the spring in the compressed state will buffer the sliding process of the first curved plate, thereby making the second curved plate more stable in the process of fixing the round tube. Due to the use of the telescopic rod, when the spring is in a compressed state, the telescopic rod can prevent the spring from deforming, thereby providing a certain degree of protection for the spring.

[0013] 3. Due to the arrangement of the bent plate, the second fixing member and the threaded rod, when the second curved plate needs to slide along the slideway toward the first curved plate, the staff can tighten the threaded rod threadedly connected to the bent plate to make the end of the threaded rod push the second curved plate to slide. Since the second fixing member passes through the bent plate and is threadedly connected to the slideway, it is convenient for the staff to disassemble and install the clamping device.

[0014] 4. Due to the setting of the rubber pad, when the round tube is fixed between the first arc plate and the second arc plate, the rubber pads on the first arc plate and the second arc plate will contact the surface of the round tube, thereby being able to provide a certain degree of protection for the round tube.

DETAILED DESCRIPTION

[0019] The embodiment of the present application provides a positioning device for processing round tubes, thereby solving the technical problem that the positioning device in the prior art solution cannot fix round tubes of different diameters at the same time due to its relatively simple structure, which leads to limitations in the use of the positioning device and affects the efficiency of round tube processing.

[0020] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] A positioning device for processing round tubes, such as Figure 1As shown, it includes a base plate 1, a first curved plate 2 for supporting a circular tube, a second curved plate 3 for fixing the circular tube, a buffer device 4 for buffering the second curved plate 3, a clamping device 5 for clamping the second curved plate 3, a slide 6 for limiting the first curved plate 2, and a first fixing member 7 for fixing the first curved plate 2. Two groups of slides 6 symmetrically arranged are arranged on the base plate 1. The first curved plate 2 and the second curved plate 3 are both slidably connected to the two groups of slides 6. The buffer device 4 is arranged between the first curved plate 2 and the second curved plate 3. The clamping device 5 is arranged on the slide 6. The slide 6 is provided with a plurality of groups of circular through holes 61 arranged in a linear array. The first fixing member 7 is connected to the first curved plate 2 through the circular through holes 61.

[0023] Two groups of symmetrically placed slideways 6 are fixedly connected to the top of the bottom plate 1. Both ends of the first curved plate 2 and the second curved plate 3 are slidably connected to the two groups of slideways 6, and both ends of the first curved plate 2 and the second curved plate 3 are clamped on the two groups of slideways 6. Two groups of symmetrically placed buffer devices 4 are fixedly connected between the first curved plate 2 and the second curved plate 3. A clamping device 5 is fixedly connected to the top of the two groups of slideways 6. The two groups of clamping devices 5 are respectively against the second curved plate 3. A plurality of groups of circular through holes 61 arranged in a linear array are provided on the two groups of slideways 6. The first fixing member 7 is preferably a bolt. The two groups of first fixing members 7 pass through the corresponding circular through holes 61 and are threadedly connected to the two ends of the first curved plate 2.

[0024] Due to the arrangement of the bottom plate 1, the first curved plate 2, the second curved plate 3, the buffer device 4, the clamping device 5, the slideway 6 and the first fixing member 7, when it is necessary to fix the round tube, the staff first places the round tube on the curved groove on the first curved plate 2, and then rotates the two sets of clamping devices 5 at the same time, so that the two sets of clamping devices 5 are pressed against the second curved plate 3 at the same time, and push the second curved plate 3 to slide along the slideway 6 toward the first curved plate 2. When the curved groove on the second curved plate 3 is firmly pressed against the top of the round tube, the round tube can be fixed at this time. When the clamping device 5 pushes the second curved plate 3 to slide along the slideway 6 toward the first curved plate 2, the buffer device 4 will be subjected to the pressure of the second curved plate 3, so that the buffer device 4 can produce a buffering effect on the sliding process of the first curved plate 2, and then the second curved plate 3 can be made more stable in the process of fixing the round tube. Since the spacing between the first arc plate 2 and the second arc plate 3 can be adjusted by the cooperation between the clamping device 5 and the buffer device 4, round tubes of different diameters can be fixed between the first arc plate 2 and the second arc plate 3. Since the two sets of slideways 6 are provided with a plurality of groups of circular through holes 61 arranged in a linear array, and the two sets of first fixing members 7 respectively pass through the corresponding circular through holes 61 and are threadedly connected to the two ends of the first arc plate 2, the height of the first arc plate 2 can be adjusted by adjusting the position of the first arc plate 2 on the two sets of slideways 6 and fixing it with the two sets of first fixing members 7, thereby greatly increasing the practicality of the positioning device.

[0025] like Figure 2 As shown, the buffer device 4 includes a spring 41 for buffering the second arc plate 3 and a telescopic rod 42 for limiting the spring 41. The spring 41 is arranged around the telescopic rod 42. The telescopic end of the telescopic rod 42 is connected to the second arc plate 3, and the other end is connected to the first arc plate 2.

[0026] The telescopic end of the telescopic rod 42 is fixedly connected to the bottom end of the second arc plate 3, and the other end is connected to the top end of the first arc plate 2. The spring 41 is arranged around the telescopic rod 42, and one end of the spring 41 is fixedly connected to the bottom end of the second arc plate 3, and the other end is connected to the top end of the first arc plate 2.

[0027] Due to the setting of the spring 41, when the clamping device 5 pushes the second curved plate 3 to slide along the slideway 6 toward the first curved plate 2, the second curved plate 3 will compress the spring 41, and the spring 41 in the compressed state will have a buffering effect on the sliding process of the first curved plate 2, thereby making the second curved plate 3 more stable in the process of fixing the round tube. Due to the setting of the telescopic rod 42, when the spring 41 is in the compressed state, the telescopic rod 42 can prevent the spring 41 from deforming, thereby playing a certain protective role for the spring 41.

[0028] like Figure 2As shown, the pressing device 5 includes a bending plate 51, a second fixing member 52 for fixing the bending plate 51, and a threaded rod 53 for pressing the second curved plate 3. The second fixing member 52 is connected to the bending plate 51 and the slideway 6. The threaded rod 53 is threadedly connected to the bending plate 51, and the end of the threaded rod 53 abuts against the second curved plate 3. A threaded handle 531 is provided on the threaded rod 53.

[0029] The second fixing member 52 is preferably a bolt. The second fixing member 52 passes through the bent plate 51 and is threadedly connected to the slideway 6. A threaded handle 531 is fixedly connected to the top of the threaded rod 53. The threaded handle 531 facilitates the staff to rotate the threaded rod 53.

[0030] Due to the arrangement of the bent plate 51, the second fixing member 52 and the threaded rod 53, when it is necessary to slide the second curved plate 3 along the slideway 6 toward the first curved plate 2, the staff can tighten the threaded rod 53 threadedly connected to the bent plate 51, so that the end of the threaded rod 53 can push the second curved plate 3 to slide. Since the second fixing member 52 passes through the bent plate 51 and is threadedly connected to the slideway 6, it is convenient for the staff to disassemble and install the clamping device 5.

[0031] like Figure 3 As shown, rubber pads 8 are provided on both the first arc-shaped plate 2 and the second arc-shaped plate 3 .

[0032] A plurality of groups of rubber pads 8 arranged in an arc-shaped array are fixedly connected to the arc-shaped grooves of the first arc-shaped plate 2 and the second arc-shaped plate 3 for abutting against the circular tube.

[0033] Due to the provision of the rubber pad 8, when the round tube is fixed between the first arc plate 2 and the second arc plate 3, the rubber pad 8 on the first arc plate 2 and the second arc plate 3 will contact the surface of the round tube, thereby being able to provide a certain degree of protection for the round tube.
