The chain plates usually have holes for installing pins. Different types of leaf chains have different shapes, sizes and thicknesses of chain plates to adapt to different working environments and load requirements.

[0003] In the prior art, when detecting the thickness of the chain plate, a vernier caliper is usually used for detection. This is because the vernier caliper has a high measurement accuracy, which can generally reach the level of 0.02 mm or 0.05 mm, and can meet the measurement requirements of the thickness of the chain plate in most cases. It is also simple to operate and can simultaneously measure the thickness, width and other dimensions of the chain plate, and has a variety of functions. However, since the vernier caliper clamps the chain plate through measuring claws, when the two surfaces of the chain plate contacting the measuring claws are not parallel, one of the measuring claws of the vernier caliper is in point contact with the chain plate, which causes errors in the thickness measurement of the chain plate. Therefore, in view of the above problems, a plate thickness detection device for plate chain processing is proposed. Summary of the invention

[0004] In order to solve the problem proposed in the above background technology that the vernier caliper clamps the chain plate through measuring claws, when the two surfaces of the chain plate contacting the measuring claws are not parallel, one of the measuring claws of the vernier caliper is in point contact with the chain plate, thereby causing errors in the measurement of the chain plate thickness, the present invention provides a plate thickness detection device for plate chain processing.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown, the present invention provides a plate thickness detection device for plate chain processing, including a main scale component 1 and a vernier 2, the vernier 2 is slidably connected to the surface of the main scale component 1, and also includes a connecting frame 3, the connecting frame 3 is fixedly installed at the bottom of the vernier 2; a vernier component 4, the vernier component 4 is slidably connected to the inside of the connecting frame 3, and the number of the vernier components 4 is three; an extrusion block 5, the extrusion block 5 is fixedly installed on the side of the vernier component 4; a reset component 6, the reset component 6 is fixedly installed at both ends of the side of the connecting frame 3; a positioning bar 7, the positioning bar 7 is arranged on one side of the connecting frame 3 and is located inside the reset component 6.

[0033] The three vernier assemblies 4 are arranged so that they can be close to the workpiece during measurement. After the three vernier assemblies 4 are moved to the maximum value inside the connecting frame 3 by pressure, the position is the same as that of the conventional outer measuring claws, and will not affect the measured readings. When the vernier assemblies 4 move, the extrusion blocks 5 connected to the vernier assemblies 4 also move accordingly. The extrusion blocks 5 can squeeze the corresponding positioning bars 7 to move the positioning bars 7 in the horizontal direction. In this way, when the connecting frame 3 moves to the minimum value during measurement, if the surface of the workpiece is flat, the scale lines pointed to by the three positioning bars 7 driven by the three extrusion blocks 5 are the same; if the surface of the workpiece is uneven, the scale lines pointed to by the three positioning bars 7 driven by the three extrusion blocks 5 are different, so as to determine whether the surface of the workpiece is flat, and the flatness of the workpiece surface can be obtained according to the scale difference.

[0034] like Figure 3 As shown, the cursor assembly 4 includes a positioning cursor 401, an active clamping plate 402 and a first spring 403. The active clamping plate 402 is slidably connected to the inside of the connecting frame 3, the positioning cursor 401 is slidably connected to the middle of the active clamping plate 402, and the first spring 403 is arranged on both sides of the positioning cursor 401. The first spring 403 makes the positioning cursor 401 protrude in the direction of the outer measuring claw on the main scale assembly 1 inside the connecting frame 3.

[0035] The first spring 403 can push the positioning cursor 401 toward the direction close to the outer measuring claw on the main scale assembly 1 without external force, so that when the positioning cursor 401 is squeezed by the moving connecting frame 3 during measurement, when the workpiece is uneven, the positioning cursor 401 can also be close to the workpiece, ensuring that the positioning bar 7 can stably contact with the squeezing block 5 under pressure, and the movable clamping plate 402 can only slide up and down inside the connecting frame 3, so as to facilitate the adjustment of the position of the positioning cursor 401;

[0036] When using the inner measuring claws to measure the aperture, it is necessary to first move the connecting frame 3 to the leftmost side of the surface of the main scale assembly 1, at which time the first spring 403 is in a compressed state, and then place the inner measuring claws in the hole. The elastic force of the first spring 403 can quickly separate the two inner measuring claws, thereby facilitating the detection of the aperture.

[0037] The positioning cursor 401 and the movable clamping plate 402 are both able to slide inside the connecting frame 3. By changing the positions of the three cursor components 4, workpieces of different sizes can be inspected, and the application range is wide.

[0038] like Figure 4 As shown, the positioning cursor 401 includes a movable block 4011, a positioning block 4012, a first stop block 4013 and a second stop block 4014, the first stop block 4013 and the second stop block 4014 are fixedly installed at both ends of the movable block 4011, the positioning block 4012 is fixedly installed on one side of the movable block 4011, the movable clamping plate 402 is slidably connected to the surface of the movable block 4011 and is located between the first stop block 4013 and the second stop block 4014, and the length and width of the side of the positioning block 4012 close to the movable block 4011 are both smaller than the length and width of the side away from the movable block 4011.

[0039] The movable block 4011 is capable of sliding conveniently inside the connecting frame 3, and the positioning block 4012 is capable of being blocked after entering a certain distance inside the vernier 2 due to its shape. At this time, the cooperation between the positioning block 4012, the connecting frame 3 and the vernier 2 has the same effect as a conventional vernier caliper, thereby facilitating reading. The second stopper 4014 is used to block the movable clamping plate 402 to prevent the movable clamping plate 402 from separating from the movable block 4011. The first stopper 4013 and the movable clamping plate 402 cooperate with each other, and the first spring 403 is located between the two and exerts elastic force so that the positioning block 4012 is always close to the workpiece.

[0040] like Figure 6As shown, the extrusion block 5 is fixed to the surface of the positioning block 4012 and is located on the same side as the positioning strip 7. The lengths of the three extrusion blocks 5 increase from top to bottom. The extrusion block 5 is in an "L" shape. There are three positioning strips 7 and they are arranged in sequence along the width direction of the connecting frame 3. The positioning strip 7 is a right-angled trapezoid. The three extrusion blocks 5 can be in pressure contact with the corresponding three positioning strips 7 when moving along the length direction of the movable block 4011.

[0041] The three extrusion blocks 5 are able to contact and squeeze the positioning bar 7 when the positioning cursor 401 moves. By pushing the positioning bar 7, when the surface of the workpiece is uneven, the three positioning bars 7 will be misaligned, and the scale lines pointed to by the tops of the three positioning bars 7 are different, so that the surface flatness of the workpiece can be easily judged.

[0042] like Figure 6 As shown, the reset assembly 6 includes a fixing frame 601, a guide column 602 and a second spring 603. The fixing frame 601 is fixedly mounted on the surface of the connecting frame 3. Three guide columns 602 are equidistantly mounted inside the fixing frame 601. The second spring 603 is sleeved on the surface of the guide column 602. The positioning bar 7 slides on the surface of the guide column 602. The second spring 603 moves the positioning bar 7 toward the direction of the outer measuring claw on the main scale assembly 1 through the elastic force.

[0043] The fixed frame 601 is used to position the guide column 602 and the second spring 603. The positioning bar 7 can slide on the surface of the guide column 602, and the second spring 603 can use elastic force to make the positioning bar 7 close to the direction of the outer measuring claw on the main scale assembly 1, thereby maintaining the stability of the position of the positioning bar 7 when the extrusion block 5 squeezes the positioning bar 7 to move.

[0044] like Figure 1 As shown, the surface of the main scale assembly 1 is provided with a main scale scale, the surface of the vernier 2 is provided with a vernier scale, and the positioning bar 7 is parallel to the scale lines of the vernier scale on the surface of the vernier 2.

[0045] The scale setting is prior art and is well known to those skilled in the art, so it is not shown in the figure. The positioning bar 7 is parallel to the scale line and can ensure stable movement when moving, thereby ensuring the accuracy of the reading.

[0046] The working principle and use process of the present invention:

[0047] When the outer measuring claw is used to detect the thickness of the workpiece, first move the three cursor components 4 so that the three cursor components 4 are all located within the area of ​​the workpiece to be measured, and place the workpiece to be measured between the outer measuring claw and the positioning cursor 401. Then move the connecting frame 3 to make the positioning cursor 401 contact with the workpiece to be measured by pressure, and make the positioning block 4012 contact with the connecting frame 3 by pressure, and then turn the set screw on the cursor 2 to fix it. During the movement of the positioning cursor 401, the three extrusion blocks 5 respectively connected to the positioning block 4012 can push the corresponding positioning bar 7 to move. When the scale lines pointed to by the three positioning bars 7 are the same, it means that the surface of the workpiece is flat. When the scale lines pointed to by the three positioning bars 7 are different, it means that the surface of the workpiece is uneven, and the size of the inclination of the workpiece is judged by the distance between the scale lines.

[0048] When using the inner measuring claw to detect the aperture of the workpiece, first move the connecting frame 3 toward the inner measuring claw on the main scale assembly 1, then place the inner measuring claws on the main scale assembly 1 and the vernier 2 in the hole, cancel the control of the position of the connecting frame 3, and under the action of the elastic force of the first spring 403, the connecting frame 3 moves away from the outer measuring claw on the main scale assembly 1, thereby facilitating the measurement of the aperture.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
