The positioning bolt 4 can fix the moving frame 3, and the position of the moving frame 3 can be fixed at any point on the outer wall of the column 2. The positioning bolt 4 is a prior art and can be realized by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. A manual press main body 5 is arranged on the front surface of the moving frame 3. A force gauge 10 is arranged on the front surface of the manual press main body 5. A manual press lever 8 is arranged on the right surface of the manual press main body 5. The manual press main body 5 and the manual press lever 8 together form a manual press. The manual press is a prior art and can be realized by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. Pressing the manual press lever 8 can drive the force gauge 10 to move slowly downward. The force gauge 10 is also a prior art. The bottom end of the force gauge 10 is a detection head. When receiving pressure, the display screen on the front surface of the force gauge 10 will display the pressure value. By changing the position of the force gauge 10, the magnitude of the pressure can be accurately controlled. A positioning component is arranged on the upper surface of the base 1. The positioning component can clamp and fix the rubber product to ensure the stability when the rubber product is pressed. Common rubber products include rubber rings and rubber blocks, etc.

[0032] Referring to Figure 1 , Figure 3 , Figure 4 , the positioning component includes a fixed seat 61. A motor 62 is arranged on the front surface of the fixed seat 61.

A guide groove 601 is opened on the rear surface of the guide block 64. A clamping component is arranged inside the fixed seat 61. The clamping component can clamp and fix the rubber product to be fixed. And under the influence of the guide block 64, the rubber product will be clamped in the middle position of the fixed seat 61 to ensure the position is centered and the force is evenly distributed. A limit component is arranged on the outer wall of the manual press lever 8.

[0033] Referring toFigure 1 , Figure 3 , Figure 4 , the clamping assembly includes a moving block 71. A clamping plate 72 is fixedly connected to the upper surface of the moving block 71. A T-shaped block 73 is fixedly connected to the front surface of the clamping plate 72. There are two sets of the T-shaped block 73, the moving block 71 and the clamping plate 72, which are symmetrically distributed about the center line of the fixed seat 61. The T-shaped block 73 fits into the guiding groove 601.

[0034] Refer to Figure 1 , Figure 5 , the limiting assembly includes a fixed ring 93. The fixed ring 93 is elastically connected to a toothed ring 91 through a compression spring 92. A toothed groove 901 is formed on the right surface of the manual press body 5. The left surface of the toothed ring 91 fits into the toothed groove 901. A pull rod 94 is fixedly connected to the rear surface of the toothed ring 91. The toothed ring 91 and the pull rod 94 will move synchronously.

[0035] Refer to Figure 1 , Figure 3 , Figure 4 , the lower surface of the fixed seat 61 is fixedly connected to the upper surface of the base 1. A threaded rod 63 penetrates and is rotatably connected to the front surface of the fixed seat 61. The threaded rod 63 penetrates and is threadedly connected to the front surface of the guiding block 64. When the threaded rod 63 rotates, it can drive the guiding block 64 to move in the front-rear direction. The left end and the right end of the rear surface of the guiding block 64 are set as inclined surfaces. The guiding groove 601 is formed in a T shape and is opened at the inclined surface of the rear surface of the guiding block 64.

[0036] Refer to Figure 1 , Figure 3 , Figure 4 , the fixed seat 61 is set in a U shape. The moving block 71 is slidably connected to the inner wall of the fixed seat 61. The clamping plate 72 penetrates and is slidably connected to the right surface of the fixed seat 61. The right end of the front surface of the moving block 71 is set as an inclined surface. The inclined surfaces of the moving block 71 and the guiding block 64 are in contact. The T-shaped block 73 is set in a T shape. The rear surface of the T-shaped block 73 is fixedly connected to the inclined surface of the front surface of the moving block 71. The T-shaped block 73 is slidably connected to the inner wall of the guiding groove 601. When the guiding groove 601 moves, it will squeeze the T-shaped block 73 and then drive the T-shaped block 73 to move horizontally.

[0037] Refer to Figure 1 , Figure 5, the tooth groove 901 is formed in a gear shape, the left surface of the tooth ring 91 is set in a gear shape, the fixing ring 93 is fixedly connected to the outer wall of the pressure bar 8 of the manual press, the tooth ring 91 is inserted into the inner wall of the tooth groove 901, the tooth ring 91 will be limited, and then the pressure bar 8 of the manual press will also be limited. The tooth ring 91 is slidably connected to the outer wall of the pressure bar 8 of the manual press. One end of the compression spring 92 is fixedly connected to the right surface of the tooth ring 91, and the other end of the compression spring 92 is fixedly connected to the left surface of the fixing ring 93. When the tooth ring 91 moves to the right, it will disengage from the tooth groove 901 to release the limit, and will squeeze the compression spring 92 to generate a reaction force.

[0038] Working principle: When the device is in use, first adjust the moving frame 3 to an appropriate height according to the model of the rubber product to be pressed. When adjusting, first loosen the positioning bolt 4, then move the moving frame 3 longitudinally. When it reaches the appropriate height, tighten the positioning bolt 4 to fix the moving frame 3. At this time, the dynamometer 10, the main body 5 of the manual press, and the pressure bar 8 of the manual press will all be at an appropriate height. Then place the rubber product into the opening on the upper surface of the fixing seat 61, and start the motor 62 to drive the threaded rod 63 to rotate. The rotating threaded rod 63 will drive the guide block 64 and the guide groove 601 to move forward. The forward-moving guide groove 601 will squeeze the T-shaped block 73, and then drive the T-shaped block 73, the moving block 71, and the clamping plate 72 to move towards the middle of the fixing seat 61. The clamping plates 72 on both sides will clamp and fix the rubber product. After the fixing is completed, turn off the motor 62, and the device will remain stable.

[0039] Then pull the pull rod 94 to the right to drive the tooth ring 91 to move to the right. The tooth ring 91 moving to the right will disengage from the tooth groove 901 to release the limit on the pressure bar 8 of the manual press. The pressure bar 8 of the manual press can rotate downward, and the tooth ring 91 moving to the right will also squeeze the compression spring 92 to generate a reaction force. At this time, slowly press down the pressure bar 8 of the manual press. Driven by the main body 5 of the manual press, the dynamometer 10 will slowly move downward. Gradually, the detection head at the bottom of the dynamometer 10 will contact the rubber product and gradually generate pressure. The display screen on the front surface of the dynamometer 10 will display the pressure value. When the appropriate value is reached, release the pull rod 94. The reaction force of the compression spring 92 will push the tooth ring 91 and the pull rod 94 to move to the left. The tooth ring 91 will be inserted into the tooth groove 901 to limit the pressure bar 8 of the manual press and the dynamometer 10 to ensure the stability of the dynamometer 10 and enable stable pressing. Then use standard parts to measure the length of the rubber product that is mostly a rubber ring under the pressure that needs to be detected for deformation length. Then judge whether it is qualified according to the measured length.

[0040] After the measurement is completed, pull the lever 94 to the right to release the limit on the gear ring 91, the pressing rod 8 of the manual press, and the dynamometer 10. Then, move the pressing rod 8 of the manual press upward to raise the dynamometer 10 to the highest point. Then, start the motor 62 to drive the threaded rod 63 to reverse, thereby driving the guide block 64 and the guide groove 601 to move backward. The moving guide groove 601 and the guide block 64 will squeeze the moving block 71 and the T-shaped block 73, thereby driving the moving blocks 71, the clamping plates 72, and the T-shaped blocks 73 on both sides to separate and release the clamping of the rubber product. Then, remove the rubber product.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
