Description

Technical Field

[0001] The utility model relates to the technical field of clamping tooling equipment, in particular to a pipe auxiliary clamping tooling. Background Art

[0002] In the process of processing large-diameter pipes, stable and efficient clamping of the pipes is a prerequisite for ensuring the normal processing. The existing pipe clamping tooling can meet the clamping requirements, but the existing tooling lacks a driving device, which means that when the pipe needs to be rotated, it can only be operated manually. For large-diameter pipes, it is difficult to manually drive the pipe to rotate, which greatly reduces work efficiency and poses a safety hazard.

[0003] In view of this, we propose a pipe auxiliary clamping tool to solve the existing problems. Utility Model Content

[0014] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Embodiment 1

[0016] like Figure 1 and Figure 2 As shown, the utility model proposes a pipe auxiliary clamping tool, including a base 1, two parallel sliding guide rods 2 are arranged on both sides of the top surface of the base 1 along its length direction, and a fixed seat 3 is slidably connected to the two sliding guide rods 2, and a concave groove for accommodating the pipe is provided at one end of the top surface of the fixed seat 3, and a belt 7 for tightening the outer circumference of the pipe is provided in the concave groove, and a motor 6 is provided on one side of the outer wall of the fixed seat 3, and the output end of the motor 6 passes through the fixed seat 3 and is driven and connected to a transmission gear 4 arranged inside the fixed seat 3, and the transmission gear 4 is meshed and connected with a driving wheel group 5, and the driving wheel group 5 is in friction contact with the belt 7 to drive the pipe to rotate.

[0017] In the embodiment, the driving wheel group 5 includes a first step gear 501 and a second step gear 502. The first step gear 501 is meshed with the transmission gear 4 through a small tooth portion, and the large tooth portion of the first step gear 501 is meshed with the small tooth portion of the second step gear 502. The outer wall of the large gear ring of the second step gear 502 is covered with a rubber ring, and the second step wheel is in friction contact with the belt 7 through the rubber ring.

[0018] In the embodiment, the opening diameter of the concave groove of the fixing seat 3 is equal to the diameter of the pipe, so that the pipe can be firmly placed in the fixing seat 3 .

[0019] In the embodiment, there are at least two fixing seats 3, which are used to be flexibly distributed and fixed on multiple supporting points at the bottom of the pipe so that the pipe can be kept horizontal.

[0020] In the embodiment, freely rotatable bearings are provided at the bottom of the concave groove of the fixing seat 3 and at both ends of the opening of the concave groove, and the bearings are in rolling contact with the pipe.

[0021] The working principle of a pipe auxiliary clamping tool based on the first embodiment is: when the utility model is used, the pipe to be processed is placed in the concave groove of the fixing seat 3. Since the opening diameter of the concave groove is equal to the diameter of the pipe, the pipe can be stably placed in the concave groove. The sliding guide rod 2 is slidably connected to at least two fixing seats 3. The fixing seat 3 slides along the sliding guide rod 2 to adjust the position, thereby adapting to the length of the pipe, and at the same time providing flexible positioning and support clamping for the pipe. The motor 6 on one side of the outer wall of the fixing seat 3 is started, and the output end of the motor 6 passes through the fixing seat 3 to drive the transmission gear 4 installed inside the fixing seat 3 to rotate, and the transmission gear 4 and the drive gear 4 are connected to the drive gear 4. The driving wheel group 5 is meshed and connected. Specifically, the transmission gear 4 is meshed and transmitted with the small teeth of the first step gear 501, and the large teeth of the first step gear 501 are meshed and connected with the small teeth of the second step gear 502. The power of the motor 6 is transmitted to the second step gear 502 through these two gears. The outer wall of the large gear ring of the second step gear 502 is covered with a rubber ring. The material of the rubber ring allows sufficient friction to be generated between the rubber ring and the belt 7. Since the belt 7 is tightly clamped on the surface of the pipe, when the pipe needs to be rotated, it is only necessary to continue to rotate the motor 6, and finally drive the pipe to rotate through the meshing transmission of the transmission gear 4 and the driving wheel group 5.

[0022] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
