Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a mold steel perpendicularity testing device. Background Technology

[0002] Perpendicularity is a tolerance requirement in directional tolerance that controls the angle between the measured element and the datum element. It is divided into perpendicularity requirements for a given plane, a given direction, and arbitrary directions, and is represented by the symbol ⊥. According to the characteristics of the measured element and the datum element, perpendicularity evaluates the perpendicularity between lines, between planes, or between a line and a plane. When measuring the perpendicularity of some workpieces, a perpendicularity measuring device is required.

[0003] For example, Chinese patent CN217276115U discloses a mold steel verticality testing device, which relates to the field of workpiece inspection technology. This utility model includes a support device, a power device, a clamping device, a pushing device, and a testing device. The support device includes a supporting base plate, an L-shaped plate, a vertical plate, and a download plate. The power device includes a motor bracket and gears. The clamping device includes a slide rail and a toothed straight plate. The pushing device includes a contact frame, a pushing plate, a sliding plate, and a T-shaped slider. The testing device includes a column and a mold steel block. In this utility model, the mold steel block to be tested is placed on the download plate. The rotary motor is controlled to rotate so that the clamping plate presses the mold steel block to be tested. The entire pushing device is pushed by the handle. When the contact frame contacts the mold steel block to be tested, it stops. The circular slider moves up and down along the column, and the verticality test gauge also moves up and down accordingly to complete the test.

[0004] While the mold steel verticality testing device in the aforementioned patent has many advantages and a high safety factor, the testing process requires moving a circular slider up and down along the column, causing the verticality test gauge to move up and down as well. This is labor-intensive and reduces practicality when testing a large quantity of mold steel. Utility Model Content

It solves the problem that when testing, it is necessary to move a circular slider up and down along the column, and the verticality test gauge moves up and down accordingly, which is labor-intensive and reduces practicality when testing a large number of mold steels.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mold steel verticality testing device, including a base, a support frame is provided on the left side of the upper surface of the base, a moving mechanism is provided on the right side of the upper surface of the base, and a pressing mechanism is provided on the upper surface of the support frame; The moving mechanism includes a fixed plate fixed to the right side of the upper surface of the base.

A verticality measuring instrument body is provided on the left side of the fixing block, and the right side of the fixing block is in contact with the left side of the moving plate.

[0007] Furthermore, the telescopic rod includes a first sliding rod, and a second sliding rod is slidably connected inside the first sliding rod.

[0008] Furthermore, the movable plate moves linearly left and right on the upper surface of the base.

[0009] Furthermore, the pressing mechanism includes a second electric push rod fixed to the upper surface of the support frame by a mounting bracket.

This mold steel verticality testing device, when the handwheel is turned, moves the moving plate to the left on the upper surface of the base under the limiting action of the telescopic rod and two sliding rods. This causes the detection end of the verticality test gauge to move to the left and contact the right side of the mold steel after it is pressed down and fixed. After contact, the handwheel can be stopped, and then the first electric push rod can be started to move the verticality test gauge body up and down.

[0013] 2. This mold steel verticality testing device allows the mold steel to be tested to be placed on the upper surface of a support platform, positioned at the center of the platform and parallel to it. Then, the second electric push rod is activated, causing the lower pressure plate to move downwards and press the mold steel down to fix it on the upper surface of the support platform, thus improving the stability of the test. During testing, the second motor can be activated to rotate the pressed and fixed mold steel to test its verticality, thereby improving testing efficiency. Attached Figure Description

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.

[0018] Please see Figures 2 to 3 In order to save labor when testing a large number of mold steels, the moving mechanism 3 in this embodiment includes a fixed plate 301 fixed to the right side of the upper surface of the base 1. The fixed plate 301 is internally threaded with a threaded rod 302. A handwheel 303 is fixed to the right side of the threaded rod 302. A moving plate 304 is rotatably connected to the left side of the threaded rod 302 through a bearing.

[0019] In this embodiment, the lower surface of the movable plate 304 is in contact with the upper surface of the base 1. A telescopic rod 305 is provided inside the upper side of the fixed plate 301. The left side of the telescopic rod 305 is fixedly connected to the right side of the movable plate 304.

A connecting plate 307 is provided on the upper left side of the movable plate 304.

[0020] In this embodiment, by rotating the handwheel 303, the threaded rod 302 is driven to rotate inside the fixed plate 301. The moving plate 304 moves to the left on the upper surface of the base 1 under the limiting action of the telescopic rod 305 and the two sliding rods 306, which drives the detection end of the verticality measuring instrument body 310 to move to the left and contact the right side of the mold steel after pressing and fixing. After contact, the rotation of the handwheel 303 can be stopped.

[0021] In this embodiment, the moving mechanism 3 also includes a first electric push rod 308 fixed to the upper surface of the connecting plate 307 by a mounting bracket. The outer side of the output shaft of the first electric push rod 308 slides through the connecting plate 307 and extends to the lower side.

The efficiency of the test can be improved by setting the first electric push rod 308.

[0022] It should be noted that starting the first electric push rod 308 drives the fixed block 309 and the verticality measuring instrument body 310 to move up and down. The verticality measuring instrument body 310 on the upper and lower sides completes the inspection. Therefore, when a large number of mold steels need to be inspected, it can save the labor of inspection. During the inspection, the verticality measuring instrument body 310 can display the inspection value.

[0023] Please see Figure 4 To improve the stability and efficiency of the test, in this embodiment, the pressing mechanism 4 includes a second electric push rod 401 fixed to the upper surface of the support frame 2 by a mounting bracket. The outer side of the output shaft of the second electric push rod 401 slides through the support frame 2 and extends into the interior. The outer side of the output shaft of the second electric push rod 401 is rotatably connected to a pressing plate 402 by a bearing. The upper surface of the base 1 is rotatably connected to a support cylinder 403 by a bearing. A support platform 404 is provided on the upper surface of the support cylinder 403.

[0024] In this embodiment, the mold steel to be tested can be placed on the upper surface of the support platform 404, located at the center of the support platform 404, and placed parallel to the support platform 404. Then, the second electric push rod 401 is activated, which can drive the lower pressure plate 402 to move downward and press down and fix the mold steel on the upper surface of the support platform 404, thereby improving the stability of the test.

[0025] In this embodiment, a first bevel gear 405 is provided on the outer side of the support cylinder 403, and a second bevel gear 406 meshes with the outer side of the first bevel gear 405.

The left side of the front and rear sliding rods 306 is fixedly connected to the front and rear sides of the right side of the protective frame 408.

[0026] It should be noted that during testing, the second motor 407 can be started to drive the first bevel gear 405, the second bevel gear 406 and the support cylinder 403 to rotate, and then the mold steel that is pressed down and fixed can be driven to change the verticality test.

[0027] The working principle of the above embodiments is as follows: (1) The mold steel to be tested can be placed on the upper surface of the support platform 404, and located at the center of the support platform 404 and placed parallel to the support platform 404. Then, the second electric push rod 401 is started, which can drive the lower pressure plate 402 to move downward and press the mold steel down to fix it on the upper surface of the support platform 404, thereby improving the stability of the test. When the test is performed, the second motor 407 can be started to drive the first bevel gear 405, the second bevel gear 406 and the support cylinder 403 to rotate, and then the pressed and fixed mold steel can be driven to change the verticality test.

[0028] (2) By rotating the handwheel 303, the threaded rod 302 is driven to rotate inside the fixed plate 301. The moving plate 304 moves to the left on the upper surface of the base 1 under the limiting action of the telescopic rod 305 and the two sliding rods 306, which drives the detection end of the verticality tester body 310 to move to the left and contact the right side of the mold steel after pressing and fixing. After contact, the handwheel 303 can be stopped, and the first electric push rod 308 can be started to drive the fixed block 309 and the verticality tester body 310 to move up and down. The verticality tester body 310 on the upper and lower sides is used to complete the detection. Therefore, when a large number of mold steels need to be detected, the labor force for detection can be saved.
