Problems solved by technology

Due to the unevenness of the rock surface, the contact between the clamp and the rock surface is uneven during clamping. Sometimes the actual clamping part is very small, not only the fixing effect is limited, but also it is easy to cause the sample to be too concentrated, cracked or even crushed. Leading to sample preparation failure, therefore, the success rate of soft rock sample preparation is generally very low, resulting in great waste

Embodiment Construction

[0019] An adaptive clamping device for a rock cutter, which consists of an outer support A, an integral loading module B, an upper clamping rod C, a lower clamping rod D and a fine-tuning base E. Before loading the raw rock sample, turn on the power and pressure drive source of the clamping device; place the raw rock sample to be cut on the dot matrix formed by the lower clamping rod D, and manually adjust its posture according to the cutting position; after the sample is placed , control the lower clamping rod D to extend the lower clamping rod body D3, so that the elastic shock-absorbing contact pad D4 fits the bottom surface of the sample adaptively; control the pressure unit B1 of the overall loading module B, and drive the upper clamping support B2 to descend , when the upper clamping rod C comes into contact with the sample, the upper clamping rod support B2 stops falling; the upper clamping rod C is controlled to make the upper clamping rod body C3 stretch out, so that t...

Abstract

The invention relates to a self-adaption clamping device for a rock cutting machine. The device is characterized by consisting of an outer bracket, a whole loading module, an upper clamping rod, a lower clamping rod and a fine adjustment base. The upper clamping rod with an elastic vibration reducing contact pad and the lower clamping rod can automatically extend according to the rock surface fluctuation under control of a pressure sensor to adjust the jaw shape to keep consistent with the rock surface morphology so as to realize self-adaption clamping of country rock samples; and the fine adjustment base realizes translation and rotation fine adjustment of the cutting position through a guide rail and a rotating support. The device solves the stress concentration problem of the rock cutting machine in clamping of the country rock samples, effectively protects soft rock samples, improves the sample clamping effect and the sample production success rate, realizes fine adjustment of the cutting position after clamping of the samples, increases the flexibility, and improves the cutting efficiency.

Description

Technical field: [0001] The invention belongs to the field of development of rock testing and processing equipment, and in particular relates to an adaptive clamping device for a rock cutting machine, which is suitable for fixing and fine-tuning cutting positions when cutting rocks of various irregular shapes. technical background: [0002] Indoor rock test is one of the commonly used methods to study the physical and mechanical properties of rock. The processing and preparation of rock samples is the basis for carrying out various rock tests. Weak rock is a type of rock mass that is often encountered in engineering. It has the characteristics of low strength, easy softening and cracking when exposed to water. Destroyed under the combined action of other unfavorable factors. The existing rock cutting machine is used to fix the jig of the original rock sample as a rigid structure, and the steel beam or steel plate is in contact with the sample and exerts a clamping force. D...
