Description

Technical Field

[0001] This utility model relates to the field of transmission belt manufacturing and quality inspection, specifically to a horizontal V-belt automatic length measuring machine. Background Technology

[0002] In the field of transmission belt manufacturing and quality inspection, V-belt length measurement is a crucial step in ensuring the matching of transmission systems. Existing technologies fall into two categories: ① Manual V-belt length measurement devices: These consist of a fixed pulley, a movable pulley, a scale, and a manual tension lever. Operators manually place the V-belt onto the two pulleys, apply pre-tension using the lever, and then push the movable pulley to tension the belt. The length data is then read from the scale. Some devices are equipped with mechanical clips for positioning the movable pulley. ② Semi-automatic V-belt length measuring machines: These add a motor drive module and a tension sensor to the manual device. The movable pulley feed can be controlled by a button, and the tension sensor displays the real-time tension value. However, manual assistance is required for belt placement, and measurement data must be manually recorded into a form. Disadvantages include low automation: belt placement, alignment, and unloading all require manual operation; manual data recording is prone to errors. Summary of the Invention

[0024] The following is combined Figure 1-10 Further explanation A horizontal V-belt automatic length measuring machine includes a belt loading mechanism 1, a length measuring frame mechanism 2, and a belt unloading mechanism 3. The length measuring frame mechanism 2 includes a length measuring frame 21, on which a driving wheel unit 23 and a driven wheel unit 22 are provided. The driven wheel unit 22 includes a driven wheel slider 221 and a driven wheel push cylinder 222. The driven wheel 223 is rotatably mounted on the driven wheel slider 221. The driven wheel push cylinder 222 is mounted on the length measuring frame 21, and the other end of the driven wheel push cylinder 222 is fixed to the driven wheel slider 221. The length measuring frame 21 is provided with a length measuring frame track 211. The driven wheel push cylinder 222 pushes the driven wheel slider 221 to move along the length measuring frame track 211. The movement of the driven wheel slider 221 by the driven wheel push cylinder 222 facilitates the loading and unloading of V-belts.

[0025] A counterweight 224 is provided on the side of the driven wheel slider 221 away from the driving wheel unit 23.

[0026] The driven wheel slider 221 is equipped with a V-belt fixing wheel cylinder 225, and a V-belt fixing wheel 226 is provided at one end of the V-belt fixing wheel cylinder 225. The V-belt fixing wheel cylinder 225 pushes the V-belt fixing wheel 226 to press down the V-belt for fixing.

[0027] The driven wheel slider 221 is equipped with a driven wheel V-belt push cylinder 227, and the driven wheel V-belt push cylinder 227 is equipped with a driven wheel V-belt push plate 228. The driven wheel V-belt push cylinder 227 can push the driven wheel V-belt push plate 228, thereby pushing out the V-belt during unloading.

[0028] The drive wheel unit 23 includes a drive wheel frame 231, a drive wheel motor 232 and a drive wheel 233 are mounted on the drive wheel frame 231, the drive wheel motor 232 drives the drive wheel 233 to rotate, and a grating ruler is mounted on the side of the drive wheel frame 231.

[0029] The drive pulley frame 231 has a drive pulley V-belt push cylinder 234 on its side, and a drive pulley V-belt push plate 235 on the drive pulley V-belt push cylinder 234. The drive pulley V-belt push cylinder 234 can push the drive pulley V-belt push plate 235, thereby pushing out the V-belt during unloading.

[0030] The drive pulley frame 231 (more preferably, the drive pulley frame 231 can also move laterally via a lead screw motor structure) is equipped with a first push cylinder 236. A first slide rail 237 is provided on the drive pulley frame 231, and a first sliding block 238 is provided on the first slide rail 237. The first push cylinder 236 pushes the first sliding block 238 to move along the first slide rail 237. The PLC controls the drive pulley motor to rotate the belt 3-5 times. At this time, a grating ruler (installed on the side of the drive pulley frame 231, with a resolution of 0.001mm) can collect the actual center distance between the drive pulley 233 and the driven pulley 223, and calculate the V-belt length based on the pulley groove diameter.

[0031] The first sliding block 238 is equipped with a sliding block screw 239, and the sliding block screw 239 is equipped with a sliding block motor 240. The sliding block motor 240 drives the sliding block screw 239 to rotate. The sliding block screw 239 is threaded with a mounting arm 241, and V-belt pressure rollers 242 are provided at both ends of the mounting arm 241. The above structure enables the adjustment of the V-belt pressure rollers 242, which can press down the V-belt.

[0032] The first sliding block 238 is provided with a guide rail 243, and the mounting arm 241 is slidably mounted on the guide rail 243. The guide rail 243 can better ensure the movement stability of the mounting arm 241.

[0033] The length measuring platform mechanism 2 of this utility model includes an active wheel unit 23 that uses a grating ruler to measure length, and a driven wheel unit 22 that includes a counterweight 224 for tension feedback and adjustment. The counterweight 224 transmits the tension to the tension sensor through a wire rope and a fixed pulley system. The sensor converts the force signal into an electrical signal and feeds it back to the PLC. The PLC controls the lifting platform to adjust the height of the counterweight, thereby realizing closed-loop tension control.

[0034] The PLC sends a command to "push out the driven wheel cylinder 222", which pushes the driven wheel slider 221 to move along the guide rail to its maximum stroke. At this time, the driving wheel unit 23 moves to the preset "belt loading position" (the center distance is preset according to the V-belt model, such as 800mm) under the drive of the servo motor. After the belt loading mechanism 1 puts the V-belt into the groove of the driving wheel 233 and the driven wheel 223, it sends a "belt loading complete" signal to the PLC. The PLC sends a command to "retract the driven wheel cylinder 222", and the cylinder piston rod retracts. The driven wheel slider 221 moves under the pulling force of the counterweight device until the tension reaches the set value and stabilizes for 3 seconds. After the tension stabilizes, the V-belt pressing roller 242 presses on the top of the belt. The PLC controls the driving wheel motor to rotate the belt 3-5 times. At this time, the grating ruler (installed on the side of the driving wheel slider, with a resolution of 0.001mm) collects the actual center distance between the driving wheel and the driven wheel, and calculates the V-belt length by combining it with the groove diameter.

[0035] The unloading mechanism 3 includes an unloading unit mounting frame 31, on which at least two unloading units 32 are provided (preferably the right unloading unit 32 can be moved laterally by a screw motor structure). The unloading unit 32 includes an unloading frame 33, on which an unloading cylinder 34 is provided, on which an unloading arm mounting platform 35 is provided, and on which an unloading frame slide rail 36 is provided. The unloading cylinder 34 drives the unloading arm mounting platform 35 to move along the unloading frame slide rail 36.

[0036] A discharge arm 37 is rotatably connected to the discharge arm mounting platform 35, and a discharge arm motor 38 is provided on the discharge arm mounting platform 35, which drives the discharge arm 37 to rotate.

[0037] The unloading arm 37 includes a right-angled trapezoidal column 39 and an unloading arm baffle 310. The design of the right-angled trapezoidal column 39 and the unloading arm baffle 310 ensures that the V-belt falls on the unloading arm 37 and moves.

[0038] The unloading mechanism 3 of this utility model is in standby preparation: the left unloading arm 37 is fixed to the driven wheel 223, and the right unloading arm 37 is positioned according to the drive wheel 233 until both unloading arms are aligned with the center of the grooves of the drive wheel 233 and the driven wheel 223, and the unloading arm 37 is in a -36° standby position; upon receiving the start-up: after the measurement is completed, the PLC sends an "unloading command", the unloading arm motor 38 synchronously rotates the unloading arm 37 to the 150° unloading position, and the drive wheel V-belt push cylinder 234 and the driven wheel V-belt push cylinder 228 push the V-belt into the unloading arm. 37; Unloading of qualified products: If the PLC receives a "qualified" signal, the unloading arm motor 38 drives the arm to rotate in the opposite direction from the 150° unloading position to -36°, and the unloading cylinder 34 extends to the qualified area of ​​the receiving box, the V-belt slides into the qualified area of ​​the receiving box, and after completion, it resets to the standby position; Unloading of unqualified products: If the PLC receives a "unqualified" signal, the unloading arm motor 38 drives the arm to rotate in the opposite direction from the 150° unloading position to -36°, and the unloading cylinder 34 extends to the unqualified area of ​​the receiving box, the V-belt slides into the unqualified area of ​​the receiving box, and after completion, it resets to the standby position.

[0039] The belt mounting mechanism 1 includes a first belt mounting mechanism 11 (further preferred, the entire belt mounting mechanism can move back and forth, which can be achieved through a motor screw structure) and a second belt mounting mechanism 12. The first belt mounting mechanism 11 includes a first belt mounting frame 111, on which a first belt mounting assembly 112 is provided. The first belt mounting assembly 112 includes two first belt mounting platforms (further preferred, the right first belt mounting platform can move left and right to adapt to V-belts of different lengths, which can be achieved through a motor screw structure). A V-belt mounting post 113 is provided on the first belt mounting platform. A V-belt rotary motor 114 and a V-belt mounting arm 115 are provided on the V-belt mounting post 113. The V-belt rotary motor 114 drives the V-belt mounting arm 115 to rotate.

[0040] The V-belt mounting arm 115 is provided with a number of mounting arm grids 116. One V-belt falls into one mounting arm grid 116.

[0041] The second upper belt mechanism 12 includes a second upper belt mechanism frame 121. The second upper belt mechanism frame 121 has an upper belt mechanism lead screw 122 on at least one side. The upper belt mechanism lead screw 122 has an upper belt mechanism lead screw motor 130 on its top. The upper belt mechanism lead screw 122 is threaded with a second upper belt mechanism lifting platform 123. The second upper belt mechanism lifting platform 123 is provided with two second upper belt mechanism components 124.

[0042] The second upper belt mechanism assembly 124 includes a second upper belt mechanism assembly frame 125, a second upper belt mechanism assembly motor 126 is provided on the second upper belt mechanism assembly frame 125, and a V-belt arm 127 is provided at one end of the second upper belt mechanism assembly motor 126.

[0043] V-belt arm 127 includes a "U-shaped" belt pick-up port 128.

[0044] A second upper belt mechanism guide rod 129 (or a lead screw) is provided on one side of the second upper belt mechanism frame 121. In this scheme, a transmission belt is provided at the top to transmit the power of the upper belt mechanism lead screw to the lead screw. A second upper belt mechanism lifting platform 123 is provided on the second upper belt mechanism guide rod 129.

[0045] In this utility model, the belt mounting mechanism 1 is driven by a V-belt rotary motor 114 to rotate the V-belt mounting arm 115 from 0° to 180° (loading position). A manual or automatic feeding device places the V-belt to be tested into the swing arm V-groove (mounting arm grid 116). After feeding, the V-belt mounting arm 115 rotates back to 0° (working position), and the V-belt falls into the mounting arm grid 116. Pre-tensioning and conveying: the servo motor fine-tunes the right-side first belt mounting mechanism frame 111 to slightly tension the V-belt within the mounting arm grid 116. Subsequently, the conveying servo motor starts, and a shaped synchronous belt (preferably with a shaped synchronous belt on the V-belt mounting arm 115 and a mounting arm grid 116 on the shaped synchronous belt) drives the V-belt along the guide groove until the photoelectric sensor detects that the V-belt has reached the "take-up" position. "Take position", the synchronous belt stops running; Belt picking and transfer: The upper belt mechanism screw motor 130 of the second upper belt mechanism 12 drives the second upper belt mechanism lifting platform 123 to rise, so that the "U-shaped" belt picking port 128 of the V-belt arm 127 is aligned with the mounting arm grid 116; The second upper belt mechanism component motor 126 drives the V-belt arm 127 to rotate from the initial position to pick up the belt; Precise belt placement: The upper belt mechanism screw motor 130 drives the second upper belt mechanism lifting platform 123 to fall, so that the V-belt is aligned with the wheel grooves of the driven wheel 223 and the driving wheel 233 of the length measuring platform mechanism 2; The second upper belt mechanism component motor 126 drives the V-belt arm 127 to rotate counterclockwise, and smoothly put the V-belt into the wheel groove; The V-belt arm 127 returns to the initial position, the component returns to the standby height, and the single loading is completed.

[0046] The belt feeding mechanism 1 of this utility model feeds the V-belt to the length measuring platform mechanism 2 for length measurement, and then the unloading mechanism 3 unloads the belt.
