Description

Technical Field

[0001] This utility model belongs to the technical field of material mechanical property testing equipment, specifically relating to a high and low temperature horizontal electronic pressure testing machine that facilitates the replacement of environmental chambers. Background Technology

[0002] High and low temperature horizontal electronic pressure testing chambers simulate extreme environmental conditions by controlling the temperature and pressure within the chamber. They can stably control the temperature of products within a set range and simulate different temperature environments through constant temperature, heating, and cooling modes. Furthermore, this equipment also has pressure testing capabilities, enabling the testing of the mechanical properties of materials under specific pressures. The environmental chamber used in high and low temperature horizontal electronic pressure testing chambers is typically a high and low temperature test chamber. High and low temperature test chambers are devices used to simulate the performance and stability of products under high and low temperature environments, and are widely used in aerospace, battery, automotive, home appliance, and scientific research fields.

[0003] Existing environmental chambers are mostly fixed to the main unit with bolts, which is time-consuming and labor-intensive to replace each time, requiring professional tools. Replacing the environmental chamber of a traditional testing machine requires disassembling the transmission mechanism or using lifting equipment, which is inconvenient for the operator. Therefore, we propose a high and low temperature horizontal electronic pressure testing machine that facilitates the replacement of the environmental chamber. Utility Model Content

A movable crossbeam and a middle crossbeam are threaded to both ends of the surface of the bidirectional screw, respectively. A linear guide rail is installed on one side of the machine body, and one end of the movable crossbeam and the middle crossbeam slides on the surface of the linear guide rail.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a high and low temperature horizontal electronic pressure testing machine that facilitates the replacement of environmental chambers, including a body 1, with connecting grooves 11 symmetrically opened on both sides of the bottom of the body 1, an environmental chamber body 12 provided below the body 1, and metal sliders 13 symmetrically installed on both sides of the top of the environmental chamber body 12. The metal sliders 13 are snap-fitted to the connecting grooves 11, and an electromagnetic layer 16 is fixedly installed on the inner wall of the connecting grooves 11.

[0020] Specifically, an upper crossbeam 2 is installed at one end of the upper part of the machine body 1. Bidirectional screws 3 are symmetrically rotated on both sides of the top of the machine body 1. One end of the bidirectional screw 3 extends to the outer end of the machine body 1 and is fixedly connected to a large pulley 7. A motor 9 is fixedly installed at one end of the machine body 1. A small pulley 10 is fixedly connected to the output end of the motor 9. The large pulley 7 and the small pulley 10 are connected by a synchronous belt 8. A movable crossbeam 4 and a middle crossbeam 5 are threadedly connected to both ends of the surface of the bidirectional screw 3. A linear guide rail 6 is installed on one side of the machine body 1. One end of the movable crossbeam 4 and the middle crossbeam 5 are slidably disposed on the surface of the linear guide rail 6.

[0021] Specifically, a nano-magnetic fluid layer 17 is provided on the inner side of the connecting groove 11, and the nano-magnetic fluid layer 17 is located between the metal slider 13 and the electromagnetic layer 16.

[0022] Specifically, a connecting pipe 14 is fixedly installed at the outer end of the connecting groove 11. The inside of the connecting pipe 14 is connected to the inside of the connecting groove 11, and an installation end 15 is fixedly connected to one end of the connecting pipe 14.

[0023] Specifically, upper flanges 18 are symmetrically installed at both ends of the body 1, and multiple sets of positioning holes 19 are opened through the surface of the upper flanges 18. Lower flanges 20 are symmetrically installed at both ends of the environmental chamber body 12, and connecting holes 21 are opened through the surface of the lower flanges 20. The positioning holes 19 and the connecting holes 21 are fixedly connected by fixing bolts 22.

[0024] Specifically, a control touch screen 23 is installed on one side of the environmental chamber body 12, and the connection slot 11 is dovetail-shaped.

[0025] In this embodiment, the device controls the left and right movement of the moving crossbeam 4 by reversing the motor 9 via software. The motor 9 drives the small pulley 10, which is connected to the large pulley 7 by a high-precision circular arc tooth synchronous belt 8. This drives the large pulley 7 to rotate synchronously, which in turn drives the bidirectional screw 3 to rotate. This allows the moving crossbeam 4 and the middle crossbeam 5 to move relative to each other. The linear guide rail 6 further enhances the stability of the moving crossbeam 4 and the middle crossbeam 5 during movement. When installing the environmental chamber body 12, align the surface metal slider 13 with the connecting groove 11, and then slide it into the interior of the connecting groove 11. After the electromagnetic layer 16 is energized, it will generate magnetic attraction with the metal slider 13, thereby locking and fixing the environmental chamber body 12 to the bottom of the body 1. The nano-magnetic fluid layer 17 is injected into the space between the metal slider 13 and the electromagnetic layer 16 through the connecting pipe 14, which can adaptively compensate for the gap between the metal slider 13 and the electromagnetic layer 16, improving the sealing performance. The upper flange 18 and the lower flange 20 can be used to further fix the environmental chamber body 12 to the body 1, improving stability.
