[0002] In materials science, mechanical engineering and related fields, it is of great significance to accurately measure the friction coefficient of tubular specimens. However, most of the existing friction coefficient test devices are for flat specimens, which is inconvenient for testing the friction coefficient of tubular specimens, and the test accuracy is difficult to guarantee. Therefore, it is particularly necessary to design a test device that can accurately and conveniently measure the friction coefficient of tubular specimens. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a simple, efficient, safe and reliable tubular sample friction coefficient testing device, which drives a clamping seat to slide on a sample placing guide rail through an adjustment mechanism and fixes a tubular sample placed on the sample placing guide rail through the clamping seat and a base.

[0004] The utility model is realized through the following technical scheme, providing a friction coefficient test device for a tubular sample, comprising a base, a plurality of sample placing guide rails arranged in parallel are arranged on the base, a clamping seat is slidably arranged on the sample placing guide rails, and an adjusting mechanism for driving the clamping seat to slide is arranged on the base; the tubular sample is stably placed by the parallel sample placing guide rails; and the tubular sample is fixed by the clamping seat and the base.

[0005] As an optimization, an adjustment seat is slidably provided on the sample placing guide rail, and the adjustment seat is connected to the sample placing guide rail through a clamping mechanism; tubular specimens of different lengths are fixed by the adjustment seat slidably provided on the sample placing guide rail.

[0006] As an optimization, the clamping mechanism includes relatively arranged clamping plates, which are fixed on the adjustment seat, and a channel adapted to the sample placing guide rail is formed between the clamping plates, and the sample placing guide rail slides through the channel; the end of the clamping plate away from the adjustment seat is connected by a clamping knob; the spacing of the clamping plates is adjusted by the clamping knob, so that the adjustment seat is fixed on the sample placing guide rail.

[0007] As an optimization, the adjustment mechanism includes an adjustment knob rotatably mounted on the base, and the adjustment knob is connected to the clamping seat through a transmission mechanism. The transmission mechanism can adopt threaded transmission, gear transmission, or worm gear transmission. The power is provided by the adjustment knob and transmitted through the transmission mechanism to drive the clamping seat to slide on the sample guide rail, thereby fixing the tubular specimen.

[0008] The beneficial effects of the utility model are as follows: the tubular specimen is stably placed by means of parallel sample placement guide rails; the tubular specimen is fixed by means of a clamping seat and a base; tubular specimens of different lengths are fixed by means of an adjustment seat slidably arranged on the sample placement guide rails; the spacing between the clamping plates is adjusted by means of a clamping knob, thereby fixing the adjustment seat on the sample placement guide rails; the clamping seat is driven to slide on the sample placement guide rails by means of an adjustment knob and a transmission mechanism, thereby fixing the tubular specimen.

[0015] like Figure 1 An adjustment seat 4 is slidably provided on the sample placing guide rail 2 shown, and the adjustment seat 4 is connected to the sample placing guide rail 2 through a clamping mechanism 5; the tubular sample 7 is placed on the sample placing guide rail 2, and one end of the tubular sample 7 is close to the clamping seat 3, the adjustment seat 4 is slid to the end of the tubular sample 7 away from the clamping seat 3, and the adjustment seat 4 is fixed on the sample placing guide rail 2 through the clamping mechanism 5; the adjustment mechanism 6 is started to drive the clamping seat 3 to approach the tubular sample 7 until the clamping seat 3 and the adjustment seat 4 complete the clamping of the tubular sample 7.

[0016] like Figure 1 The clamping mechanism 5 shown includes clamping plates 501 arranged opposite to each other, the clamping plates 501 are fixed on the adjustment seat 4, and a channel adapted to the sample placement guide rail 2 is formed between the clamping plates 501, and the sample placement guide rail 2 is slidably penetrated in the channel; the end of the clamping plate 501 away from the adjustment seat 4 is connected through a clamping knob 502; the clamping knob 502 is the prior art; rotating the clamping knob 502 increases the spacing of the clamping plates 501, and slides the adjustment seat 4 to the end of the tubular sample 7 away from the clamping seat 3; rotating the clamping knob 502 in the opposite direction reduces the spacing of the clamping plates 501, and fixes the adjustment seat 4 on the sample placement guide rail 2.

[0017] like Figure 1 The shown adjustment mechanism 6 includes an adjustment knob 601 rotatably mounted on the base 1, and the adjustment knob 601 is connected to the clamping seat 3 via a transmission mechanism 602, and the transmission mechanism 602 can adopt threaded transmission, gear transmission, or worm gear transmission; the transmission mechanism 602 includes a transmission screw 6021 connected to the adjustment knob 601, and a screw hole matching the transmission screw 6021 is provided on the base 1, and the axis of the screw hole faces the clamping seat 3, and the transmission screw 6021 is rotatably mounted on the clamping seat 3; the adjustment knob 601 is rotated to drive the clamping seat 3 to slide on the sample placement guide rail 2 via the transmission mechanism 602.

[0018] In the actual production process, the tubular sample 7 is placed on the sample placing guide rail 2, and one end of the tubular sample 7 is close to the clamping seat 3; the clamping knob 502 is rotated to increase the spacing of the clamping plates 501, and the adjustment seat 4 is slid to the end of the tubular sample 7 away from the clamping seat 3; the clamping knob 502 is rotated in the opposite direction to reduce the spacing of the clamping plates 501, and the adjustment seat 4 is fixed on the sample placing guide rail 2, and the adjustment seat 4 is fixed on the sample placing guide rail 2 through the clamping mechanism 5; the adjusting knob 601 is turned to drive the clamping seat 3 to approach the tubular sample 7 through the transmission mechanism 602 until the clamping seat 3 and the adjustment seat 4 complete the clamping of the tubular sample 7.

[0019] like Figure 2 As shown, a test sample 8 is added, and the test sample 8 is placed on the tubular sample 7. The test sample 8 is connected to a force measuring mechanism, and the force measuring mechanism is arranged on a driving mechanism. The test sample and the force measuring mechanism move under the pull of the driving mechanism. Since the test sample and the tubular sample have a relative displacement, friction will be generated between the samples due to the movement. At this time, the force measuring mechanism can measure the corresponding friction and friction coefficient.
