Description

Technical Field

[0001] This utility model relates to the field of watch strap processing technology, and more specifically, to a watch strap positioning and drilling device. Background Technology

[0002] In the manufacturing process of wearable devices such as watches and fitness trackers, the drilling of watch straps is a crucial step, as the precision and consistency of the drilling directly affect the assembly effect and wearing comfort. Currently, common watch strap positioning and drilling devices on the market have significant limitations in adjusting the drilling spacing.

[0003] Most existing watch strap punching devices use a fixed punching head layout. Once the equipment is manufactured, the punching spacing is fixed and cannot be flexibly adjusted according to the actual needs of different specifications and styles of watch straps. When processing watch straps with different spacing requirements, operators often need to replace the entire punching die or make complex mechanical adjustments to the equipment. This is not only cumbersome and time-consuming, but also prone to problems such as decreased punching accuracy, hole position misalignment, and uneven spacing due to improper adjustments, seriously affecting product quality. Even if some devices claim to be able to adjust the punching spacing, their adjustment mechanisms are complex and often use the method of adjusting the position of individual punching heads one by one, making it difficult to ensure that the spacing between multiple heads remains uniform. During the adjustment process, operators need to repeatedly measure and calibrate, which is not only inefficient but also requires a high level of skill from the operators, hindering large-scale production. Therefore, improvements are needed. Utility Model Content

[0020] like Figures 1 to 6 As shown, this utility model provides a watch strap positioning and punching device, comprising: Support 1, with a long rod 2 fixedly installed on its outer surface; The drive mechanism is located on the outer surface of the bracket 1; The motion mechanism is located on the outer surface of the long rod 2; The motion mechanism includes a motion block 3, the inside of which is movably sleeved with the outer surface of the long rod 2. A fixed shaft 4 is fixedly sleeved inside the motion block 3. There are eight fixed shafts 4. A drilling head 5 is threadedly sleeved at the bottom of the outer surface of the fixed shaft 4. A connecting rod 7 is movably sleeved on the outer surface of the fixed shaft 4. A connecting shaft 8 is movably sleeved inside the connecting rod 7. Adjacent connecting rods 7 are connected by the connecting shaft 8. A fixed block 6 is fixedly sleeved on the outer surface of the rightmost fixed shaft 4. The right side of the fixed block 6 is fixedly sleeved with the outer surface of the bracket 1.

[0021] The bracket 1 serves as the basic support structure of the device, providing a mounting carrier for the long rod 2, drive mechanism, and motion mechanism. The long rod 2 guides the movement of the moving block 3, ensuring the stability of its motion trajectory. The moving block 3 can drive the fixed shaft 4 to move along the long rod 2, thereby adjusting the position of the punch head 5. The fixed shaft 4 is used to install the punch head 5 and cooperates with the connecting rod 7 to achieve position linkage. The punch head 5 directly contacts the watch strap to complete the punching operation. The connecting rod 7 cooperates with the connecting shaft 8 to connect adjacent fixed shafts 4 to form a scissor structure, enabling the fixed shaft 4 to move at equal distances. The connecting shaft 8 connects adjacent connecting rods 7, ensuring flexible rotation between the connecting rods 7. The fixed block 6 fixes the rightmost fixed shaft 4 to the bracket 1, restricting its movement and providing a fixed base point for the linkage of the scissor structure.

[0022] The drive mechanism includes: Connecting block 9, the outer surface of connecting block 9 is fixedly connected to the outer surface of bracket 1; The first cylinder 10 is fixedly connected to the outer surface of the connecting block 9 on its right side. A movable block 11 is fixedly installed at the output end of the first cylinder 10. The outer surface of the movable block 11 is fixedly connected to the outer surface of the leftmost moving block 3.

[0023] The connecting block 9 is used to fix the first cylinder 10 on the bracket 1, providing a stable mounting base for the first cylinder 10; the first cylinder 10 serves as a driving source, enabling the movable block 11 to move linearly; the movable block 11 connects the first cylinder 10 with the leftmost movable block 3, transmitting the driving force of the first cylinder 10 to the movable block 3, causing it to move along the long rod 2, thereby achieving the position adjustment of the fixed shaft 4 and the drilling head 5.

[0024] Among them, an arc-shaped block 12 is fixedly installed on the outer surface of the bracket 1, a round rod 13 is movably sleeved inside the arc-shaped block 12, a fixing plate 14 is fixedly installed at the top of the round rod 13, and a base plate 15 is fixedly installed at the bottom of the round rod 13.

[0025] The arc-shaped block 12 is fixedly connected to the bracket 1 and can move together with the bracket 1. It is in movable sleeve engagement with the round rod 13, which can provide guidance for the up and down movement of the bracket 1 and enhance the stability of the bracket 1 during movement; the fixed plate 14 and the base plate 15 are located at the two ends of the round rod 13 respectively, and together they form the upper and lower support parts of the device, providing installation positions for other related structures.

[0026] The top of the fixing plate 14 is fixedly mounted with a second cylinder 16, and the output end of the second cylinder 16 is fixedly connected to the top of the bracket 1.

[0027] The second cylinder 16 is mounted on the fixed plate 14, and its output end is connected to the bracket 1. It can provide driving force to drive the bracket 1 to move up and down as a whole, thereby realizing the up and down movement of the drilling head 5, completing the drilling action and resetting.

[0028] The bottom end of the fixed plate 14 is provided with a sliding groove 17, and a push rod 18 is slidably connected inside the sliding groove 17. The outer surface of the push rod 18 is movably sleeved with the fixed shaft 4 and the drilling head 5.

[0029] The slide groove 17 is provided at the bottom of the fixed plate 14 to provide a track for the movement of the push rod 18 and restrict the movement direction of the push rod 18. The push rod 18 is movably sleeved with the fixed shaft 4. When the fixed shaft 4 is equidistantly translated to adjust the drilling spacing, the push rod 18 will slide synchronously along the slide groove 17. At the same time, during the upward reset of the drilling head 5, the push rod 18 can push the waste material stuck in the drilling head 5 to help the waste material get out of the drilling head 5.

[0030] The base plate 15 has a third cylinder 20 fixedly installed inside, and a hinge block 21 is fixedly installed at the output end of the third cylinder 20. A movable rod 22 is hinged inside the hinge block 21.

[0031] The third cylinder 20 is installed inside the base plate 15 and serves as a drive source to drive the hinge block 21 to move linearly. The hinge block 21 connects the third cylinder 20 and the movable rod 22, transmitting the driving force of the third cylinder 20 to the movable rod 22 to drive its movement.

[0032] Among them, the end of the movable rod 22 away from the hinge block 21 is hinged to the connecting rod 23, and the outer surface of the connecting rod 23 is movably connected to the inner surface of the outer surface of the base plate 15.

[0033] The end of the movable rod 22 away from the hinge block 21 is hinged to the connecting rod 23, which can transmit the movement of the movable rod 22 to the connecting rod 23; the connecting rod 23 is internally movably connected to the outer surface of the base plate 15, and its movement trajectory is restricted by the base plate 15, so it can move towards or away from each other under the drive of the movable rod 22.

[0034] The other end of the connecting rod 23 is fixedly equipped with a clamping block 24, and the bottom end of the clamping block 24 is slidably connected to the top end of the base plate 15.

[0035] The connecting rod 23 drives the clamping block 24 to move. The clamping block 24 is slidably connected to the top of the base plate 15. When the two clamping blocks 24 move towards each other under the drive of the connecting rod 23, they can contact the watch strap and clamp it firmly to prevent the watch strap from shifting during the drilling process and ensure the drilling accuracy.

[0036] The bottom plate 15 has a positioning block 19 fixedly installed at its top, and the outer surface of the positioning block 19 is fixedly connected to the outer surface of the round rod 13.

[0037] The recessed part of the positioning block 19 can contact the pointed end of the watch strap, which plays a preliminary positioning role for the watch strap and ensures the accuracy of the watch strap's placement.

[0038] A fan 25 is fixedly installed on the outer surface of the round rod 13, and a guide tube 26 is provided on the fan 25. The outer surface of the guide tube 26 is fixedly sleeved with the inside of the round rod 13.

[0039] The blower 25 is installed on the outer surface of the round rod 13 and can generate airflow; the guide tube 26 is connected to the blower 25 and fixed inside the round rod 13, which can guide the airflow generated by the blower 25 to the top of the base plate 15, clean up the waste material that falls after drilling, and keep the base plate 15 clean.

[0040] Working principle and usage process of this utility model: When the operator needs to drill holes in the watch strap, first place the watch strap on the top of the base plate 15, and make the sharper end of the watch strap contact the concave part of the positioning block 19. Due to the design of the positioning block 19, it can achieve a good initial positioning effect for the watch strap. After the watch strap is properly placed, the operator starts the third cylinder 20. At this time, the hinge block 21 will move to the right under the drive of the third cylinder 20. At this time, the two movable rods 22 will move synchronously under the drive of the hinge block 21. At the same time, the two movable rods 22 will drive the corresponding connecting rods 23 to move. Since the outer surfaces of the two connecting rods 23 are both in movable engagement with the inner surface of the outer surface of the base plate 15, their movement trajectory will be constrained and limited by the base plate 15, so that the two connecting rods 23 move towards each other under the drive of the movable rods 22. At this time, the two clamping blocks 24 will move towards each other under the drive of the connecting rods 23. Then the outer surface of the clamping block 24 will make close contact with the watch strap and clamp it firmly, thereby completing the fixing operation of the watch strap.

[0041] Afterwards, the operator starts the second cylinder 16, which drives the bracket 1 to move downwards as a whole. At this time, the arc block 12 slides downwards along the outer surface of the round rod 13 under the action of the bracket 1. Since the arc block 12 and the round rod 13 form a sliding fit structure, it can provide guidance for the up and down movement of the bracket 1, thereby ensuring the stability of the bracket 1 during movement. At the same time, the eight fixed shafts 4 move downwards synchronously with the bracket 1, thereby driving the punching head 5 fixed at its bottom to move downwards. When the bottom end of the punching head 5 contacts the watch strap, it will punch holes in the watch strap. Since the punching head 5 and the fixed shaft 4 are connected by a threaded connection, it is convenient for the operator to disassemble and replace the punching head 5 of different specifications according to different punching needs.

[0042] After the drilling operation is completed, the waste material generated from drilling the watch strap will be stuck inside the drilling head 5. At this time, the operator controls the second cylinder 16 to drive the bracket 1 to move upward as a whole. The eight drilling heads 5 will move upward together with the fixed shaft 4. Since the outer surface of the push rod 18 is in a movable sleeve with the fixed shaft 4 and the inside of the drilling head 5, when the fixed shaft 4 moves upward, it will slide along the outer surface of the push rod 18. When the bottom end of the push rod 18 contacts the waste material stuck inside the drilling head 5, it will exert a continuous squeezing and pushing effect on the waste material. After the bracket 1 is completely reset, the waste material will be pushed off the drilling head 5 by the push rod 18 and fall to the top of the base plate 15. At this time, the operator starts the fan 25. The airflow generated by the fan 25 will be blown directionally to the top of the base plate 15 through the guide tube 26, thereby thoroughly cleaning up the fallen waste material.

[0043] When the operator needs to adjust the drilling spacing, the first cylinder 10 is activated first. At this time, the movable block 11 will move to the left under the drive of the first cylinder 10, which in turn will drive the leftmost movable block 3 to slide to the left along the outer surface of the long rod 2. During this process, the leftmost movable block 3 will drive the corresponding fixed shaft 4 to move to the left. Since the adjacent fixed shafts 4 are connected by the connecting rod 7 and the connecting shaft 8 to form a scissor linkage structure, and since the rightmost fixed shaft 4 is fixedly connected to the bracket 1 by the fixed block 6 and cannot move, it provides a fixed base point for the linkage of the scissor structure. Therefore, when the leftmost fixed shaft 4 moves, it will drive the other fixed shafts 4 to move equidistantly through the synchronous linkage of the scissor structure. At this time, the drilling head 5 and the top rod 18 connected to the fixed shaft 4 will also move equidistantly. The top rod 18 will slide smoothly along the slide groove 17 at the bottom of the fixed plate 14, and the drilling head 5 will achieve precise adjustment of the drilling spacing during the equidistant movement to meet the drilling requirements of different specifications of watch straps.
