Abstract
Description
Technical fields:
[0001] This utility model relates to the field of materials testing technology, and more specifically to a horizontal tensile testing machine. Background technology:
[0002] A horizontal tensile testing machine is a common testing device, mainly used for tensile testing of materials such as power fittings, metal materials, steel strands, and steel wire ropes.
[0003] The existing horizontal tensile testing machine includes a main frame, a rear chuck installed at the rear of the main frame, a front chuck installed in the middle, and a hydraulic cylinder installed at the front of the main frame. The front chuck is moved back and forth by the push rod of the hydraulic cylinder, so as to perform tensile testing on the test piece installed in the front and rear chucks.
[0004] Furthermore, when the testing machine performs tensile tests on the test samples, the test samples are subjected to a large tensile force. When the test samples break, they may inevitably break off from the testing machine, causing injury to the staff next to the testing machine. This results in a defect in the poor safety of the testing machine during use. Utility model content:
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a horizontal tensile testing machine. Its upper protective cover can be flipped up and down or moved back and forth, thereby meeting the protection requirements of the test specimen during installation and testing, and has a good performance.
[0006] The solution of this utility model to the aforementioned technical problem is:
[0007] A horizontal tensile testing machine includes a main frame, a front fixing plate fixed to the front part of the main frame, a hydraulic cylinder fixed to the front end face of the front fixing plate, and the end of the push rod of the hydraulic cylinder extending out of the rear wall of the front fixing plate and connected to a load sensor fixed to the front end face of the front clamp.
[0008] A rear clamp is fixed on the front end face of the rear beam of the main frame, and the rear clamp corresponds to the front clamp.
[0009] The upper and lower parts of the left and right sides of the front end face of the rear chuck are fixed with front-to-back extending guide rods. The front ends of the guide rods are fixed to the front fixing plate, and all the guide rods are inserted into the corresponding front-to-back extending guide through holes on the front chuck.
[0010] An upper protective cover is provided above the main unit frame;
[0011] The upper protective cover can slide back and forth and flip up and down.
[0012] The top surfaces of the left and right side beams of the main frame are fixed with front-to-back extending guide rails, and the bottom surfaces of the front-to-back extending sliders are formed with front-to-back extending slide grooves, with the upper part of the guide rails inserted into the corresponding slide grooves.
[0013] The upper protective cover is mounted on two sliders.
[0014] Multiple connecting seats are fixed on the top surface of the slider on the left side, and multiple connecting plates are fixed on the bottom surface of the left side plate of the upper protective cover. The connecting plates and the corresponding connecting seats are movably connected by hinge shafts.
[0015] Multiple bent connecting seats are fixed on the top surface of the slider on the right side. A permanent magnet sheet is fixed on the right side wall of the vertical plate of the bent connecting seat. The left side wall of the right vertical plate of the upper protective cover is in close contact with and adsorbed onto the permanent magnet sheet.
[0016] Connecting plates are fixed on the rear outer walls of the side beams on the left and right sides of the main frame. A push cylinder is fixed on the front wall of one of the connecting plates. The end of the push rod of the push cylinder extends out of the rear wall of the corresponding connecting plate and is fixed on the push block fixed on the rear outer wall of the corresponding slider.
[0017] The outstanding effect of this utility model is:
[0018] Compared with existing technologies, its upper protective cover can be flipped up and down or moved forward and backward. That is, when there is no obstruction at the rear of its installation location, the upper protective cover can be moved backward to install the test sample for testing. When there is an obstruction at the rear, the upper protective cover can be flipped up to install the test sample for testing. It can prevent fragments from splashing out when the test sample breaks during the test, thus providing a protective effect. Attached image description:
[0019] Figure 1 This is a partial top view of the present invention;
[0020] Figure 2 This is a partial structural diagram of the upper protective cover and the main unit frame of this utility model. Detailed implementation method:
[0021] For example, see below. Figures 1 to 2 As shown, a horizontal tensile testing machine includes a main frame 10, which includes two side beams, left and right. A rear transverse beam is fixed between the rear ends of the two side beams. The front ends of the two side beams are fixed with the same front fixing plate 11. A hydraulic cylinder 12 is fixed on the front end surface of the front fixing plate 11. A lower support block is fixed on the bottom surface of the hydraulic cylinder 12. The bottom surface of the lower support block presses against the ground. Lower support legs are fixed at the front and rear of the bottom surface of the side beams. The bottom surfaces of the lower support legs are fixed to the ground.
[0022] The end of the push rod of the hydraulic cylinder 12 extends out of the rear wall of the front fixing plate 11 and is connected to the load sensor 14 fixed to the front end face of the front chuck 13.
[0023] A rear clamp 15 is fixed on the front end face of the rear beam of the main frame 10, and the rear clamp 15 corresponds to the front clamp 13.
[0024] The upper and lower parts of the left and right sides of the front end face of the rear chuck 15 are fixed with front and rear extending guide rods 1. The front end of the guide rod 1 is fixed on the front fixing plate 11. All guide rods 1 are inserted into the corresponding front and rear extending guide through holes on the front chuck 13.
[0025] An upper protective cover 20 is provided above the main frame 10;
[0026] The upper protective cover 20 can slide back and forth and flip up and down.
[0027] Furthermore, the top surfaces of the left and right side beams of the main frame 10 are fixed with front-to-back extending guide rails 2, and the bottom surfaces of the front-to-back extending sliders 3 are formed with front-to-back extending grooves. The upper part of the guide rails 2 is inserted into the corresponding grooves. The guide rails 2 are I-shaped, and the grooves cooperate with the upper part of the guide rails 2.
[0028] The upper protective cover 20 is installed on the two sliders 3.
[0029] Multiple connecting seats 31 are fixed on the top surface of the slider 3 on the left side, and multiple connecting plates 21 are fixed on the bottom surface of the left side plate of the upper protective cover 20. The connecting plates 21 and the corresponding connecting seats 31 are movably connected by hinge shafts.
[0030] Multiple bent connecting seats 32 are fixed on the top surface of the slider 3 on the right side. A permanent magnet sheet 33 is fixed on the right side wall of the vertical plate of the bent connecting seat 32. The left side wall of the right vertical plate of the upper protective cover 20 is in close contact with and adsorbed to the permanent magnet sheet 33.
[0031] Connecting plates are fixed on the rear outer walls of the side beams on the left and right sides of the main frame 10. A push cylinder 16 is fixed on the front wall of one of the connecting plates. The end of the push rod of the push cylinder 16 extends out of the rear wall of the corresponding connecting plate and is fixed on the push block 34 fixed on the rear outer wall of the corresponding slider 3.
[0032] Another connecting plate also has a push cylinder 16 fixed on its front wall. The end of the push rod of the push cylinder 16 extends out of the rear wall of the corresponding connecting plate and is fixed on the push block 34 fixed on the rear outer wall of the corresponding slider 3.
[0033] The slide groove and the guide rail 2 have a certain gap, which ensures that when the push rods of the two push cylinders 16 push or retract, there is a small time difference, the upper protective cover 20 can still move back and forth without getting stuck.
[0034] An extension baffle 36 is fixed on the inner wall of each slider 3. The bottom surface of the extension baffle 36 is close to the top surface of the corresponding side beam of the main frame 10 and is located inside the corresponding guide rail 2.
[0035] The bottom surface of the extension baffle 36 is fixed with a brush layer 5, and the bottom surface of the brush layer 5 is in close contact with the top surface of the corresponding side beam of the main frame 10. The extension baffle 36 and the brush layer 5 can protect the guide rail 2.
[0036] A gripping part is fixed on the top surface of the upper protective cover 20.
[0037] In use, this embodiment can be installed in a location with space at the rear or in a location with space at the top. When used in a location with space at the rear, the upper protective cover 20 can be moved backward by pushing the push rod of the hydraulic cylinder 16, so that the test specimen to be tested can be installed on the front chuck 13 and the rear chuck 15. Then, by retracting the push rods of the two hydraulic cylinders 16, the upper protective cover 20 covers the area above the front chuck 13 and the rear chuck 15, and the test can be carried out. This can prevent fragments from flying when the test specimen breaks, thus providing protection.
[0038] Among them, the front part of the top surface of the two side beams is fixed with a stop block, and the rear wall of the stop block is fixed with an elastic plate 9, which can limit the movement of the upper protective cover 20 forward and reduce the impact force.
[0039] When installed in a position with available space, the upper protective cover 20 can be opened (the upper protective cover 20 can be made of transparent materials such as acrylic, and its top surface is fixed with a gripping part). The test specimen to be tested can then be installed on the front chuck 13 and the rear chuck 15. Then, the upper protective cover 20 is flipped down, and the left side wall of the right vertical plate of the upper protective cover 20 is tightly attached to and attracted to the permanent magnet sheet 33 to achieve a cover, so that the upper protective cover 20 covers the area above the front chuck 13 and the rear chuck 15, and the test can be carried out. This can prevent fragments from flying when the test specimen breaks, thus playing a protective role.
[0040] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
