Description

Technical Field

[0001] The utility model relates to the technical field of variable pitch slide table modules, in particular to a variable pitch slide table module. Background Art

[0002] The variable pitch slide module is a mechanical device that achieves module combinations of different sizes and shapes by changing the transmission ratio of the mechanism. The variable pitch slide module plays an important role in controlling the movement of objects. By controlling the motion trajectory and speed of the slider, various complex work tasks can be achieved. Therefore, it is widely used in mechanical manufacturing, industrial production, scientific research and other fields.

[0003] Existing variable-pitch slide modules are factory-set with a fixed maximum travel range, preventing users from flexibly adjusting them to meet actual needs. This means that during testing, if the size of the test object or test environment exceeds the module's preset maximum travel range, users must replace the module or redesign the test plan, which not only increases testing costs but also prolongs the test cycle. Similarly, in actual applications, slide modules lacking travel adjustment often struggle to adapt to varying workpiece sizes or changing working environments, resulting in low efficiency and even failure to meet production requirements due to a lack of travel range. Therefore, we propose a variable-pitch slide module. Utility Model Content

[0004] The purpose of the present utility model is to provide a variable pitch slide module to solve the problem proposed in the above background technology that the existing variable pitch slide module is set with a fixed maximum stroke range when leaving the factory, and the user cannot flexibly adjust it according to actual needs. This means that during the testing phase, if the size of the test object or the test environment exceeds the preset maximum stroke of the module, the user has to replace the module or redesign the test plan, which not only increases the testing cost, but also prolongs the testing cycle. Similarly, in actual applications, faced with work objects of different sizes or changing working environments, slide modules that lack stroke adjustment functions are often difficult to adapt, resulting in low work efficiency and may even be unable to meet production needs due to the inability to cover the necessary motion range.

[0005] The axle up and down groove at two ends embeds respectively in two guide rails up and down of being made up of the groove on the attachment piece, and the tooth on the attachment piece is meshed with tooth on upper sprocket wheel, the lower sprocket. The lower sprocket. The lower sprocket. The two guide rails are meshed with tooth on upper sprocket.

[0006] Compared with the prior art, the beneficial effects of the present invention are:

[0007] The variable pitch slide module, through the design of the limit plate, groove, bidirectional screw, nut plate, guide column, shaft, first gear, second gear and adjustment button, the user only needs to rotate the adjustment button to drive the first gear on the shaft and the second gear on the bidirectional screw to engage and rotate, thereby driving the nut plate to move on the bidirectional screw. Since the nut plate is connected to the lower end of the limit plate, the position of the limit plate can be adjusted, thereby flexibly changing the movable range of the mover and slider on the slide, that is, the maximum stroke of the module. This design not only greatly improves the applicability and flexibility of the module, enabling it to easily cope with work objects of different sizes and changing working environments, but also effectively avoids the testing inconvenience and increased production cost caused by fixed stroke. In addition, the setting of the guide column ensures the stability and accuracy of the nut plate during movement, further improving the working efficiency and reliability of the module.

[0013] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0014] See also Figure 1-4 The utility model provides a technical solution: a variable pitch slide module, including a base 1, with limit plates 2 provided on both sides of the base 1, and grooves 4 are opened on one side of the two limit plates 2 near the bottom. A cam shaft 3 is provided inside the base 1, and a shell 16 is fixedly installed on one side of the base 1. The front end and rear end of the top of the base 1 are fixedly installed with slide rails 5, and the centers of the two slide rails 5 are slidably connected with eight sliders 6. The top of the slider 6 is provided with a mover 7. A bidirectional screw 9 is provided in the bottom position of the base 1, and nut plates 10 are provided on the surfaces of the bidirectional screw 9 corresponding to the lower ends of the two limit plates 2. Guide columns 11 are provided on the front end and rear end of the bottom of the base 1. A shaft rod 12 is movably connected to the center position of one side of the base 1, and an adjusting button 15 is fixedly installed on one side of the shaft rod 12. The other end of the shaft rod 12 passes through the interior of the base 1 and is fixedly installed with a first gear 13. The surface of the bidirectional screw 9 corresponds to the lower end of the first gear 13 and is fixedly installed with a second gear 14. The first gear 13 is meshed with the second gear 14.

[0015] The right end of the camshaft 3 passes through the right groove 4 and the outside of the base 1 in sequence and is movably connected to a bearing fixedly installed at the top position of the outer wall of the base 1. The left end of the camshaft 3 passes through the left groove 4, the base 1 and the inside of the shell 16 in sequence and is movably connected to a bearing fixedly installed at the top position on one side of the shell 16, providing driving force for the reciprocating motion of the mover 7 and ensuring the stability and smoothness of the camshaft 3 during rotation.

[0016] There are eight movers 7, and the front and rear ends of the bottom of the eight movers 7 are fixedly connected to the top of each two groups of sliders 6, converting the rotational motion of the camshaft 3 into the linear reciprocating motion of the slider 6, thereby realizing the working stroke of the slide module.

[0017] A cam groove is provided on the surface of the camshaft 3, and followers 8 are fixedly installed at the bottom of the eight movers 7. The lower ends of the eight followers 8 penetrate into the interior of the cam groove and contact the inner wall of the cam groove. The followers 8 can perform precise reciprocating motion following the shape of the cam groove, thereby ensuring that the motion trajectory of the mover 7 and the slider 6 is accurate.

[0018] The two ends of the bidirectional screw 9 are movably connected to the bearings fixedly installed at the bottom position on both sides of the base 1. The two nut plates 10 are respectively threadedly connected to the positive thread teeth and negative thread teeth opened on both sides of the surface of the bidirectional screw 9 through the positive thread groove and negative thread groove opened on the inner wall. The upper ends of the two limit plates 2 pass through the outside of the base 1. Their function is to simultaneously drive the two nut plates 10 to move in opposite or same directions by rotating the bidirectional screw 9, thereby adjusting the position of the limit plate 2 and realizing the adjustment of the maximum stroke of the slide module.

[0019] The two ends of the two guide columns 11 respectively penetrate the outside of the two nut plates 10 and are fixedly connected to the inner wall of the base 1 to ensure the stability of the nut plates 10 during movement, prevent them from deflecting or shaking, and ensure adjustment accuracy.

[0020] A motor 17 is fixedly installed at the bottom position on one side of the shell 16. The motor 17 is fixedly connected to the main shaft through the output end on one side. A transmission wheel 18 is fixedly installed on one end of the main shaft and one side of the surface of the camshaft 3. The two transmission wheels 18 are connected by a belt 19 to provide a power source. The main shaft and the transmission wheel 18 are driven by the motor 17 to rotate, and the power is then transmitted to the camshaft 3 through the belt 19, so that it can rotate continuously and stably, thereby driving the slide module to work.

[0021] Working principle: The motor 17 is started as a power source, and drives the main shaft to rotate through its output end. The transmission wheel 18 on the main shaft rotates accordingly, and the power is transmitted to another transmission wheel 18 on the camshaft 3 through the transmission action of the belt 19, so that the camshaft 3 starts to rotate. The cam groove opened on the surface of the camshaft 3 contacts the follower 8 installed at the bottom of the eight movers 7. As the camshaft 3 rotates, the follower 8 performs reciprocating motion accurately in the cam groove. This reciprocating motion is converted into linear motion of the slider 6 on the slide rail 5 because the mover 7 is fixedly connected to the top of the slider 6. At the same time, the user can adjust the maximum stroke of the slide module by rotating the adjusting knob 15. The adjusting knob 15 drives the shaft 12 to rotate, and the first gear 13 on the shaft 12 is in contact with the The second gear 14 on the bidirectional screw 9 engages, thereby driving the bidirectional screw 9 to rotate. Since the two nut plates 10 are threadedly connected to the bidirectional screw 9 through the positive thread groove and the reverse thread groove respectively, the rotation of the bidirectional screw 9 will simultaneously drive the two nut plates 10 to move in opposite or the same directions. The movement of the nut plate 10 drives the position adjustment of the limit plate 2 connected to it, thereby realizing precise adjustment of the maximum stroke of the slide module. During the movement of the nut plate 10, the two guide columns 11 ensure the stability of the nut plate 10, prevent it from offset or shaking, and ensure the accuracy of the adjustment. In this way, through the drive of the motor 17 and the adjustment of the adjustment button 15, the variable pitch slide module can operate stably and accurately according to the preset stroke and speed.

[0022] To sum up: the variable pitch slide module, through the design of the limit plate 2, groove 4, bidirectional screw 9, nut plate 10, guide column 11, shaft 12, first gear 13, second gear 14 and adjusting button 15, the user only needs to rotate the adjusting button 15 to drive the first gear 13 on the shaft 12 to engage and rotate with the second gear 14 on the bidirectional screw 9, thereby driving the nut plate 10 to move on the bidirectional screw 9. Since the nut plate 10 is connected to the lower end of the limit plate 2, the position of the limit plate 2 can be adjusted, thereby flexibly changing the movable range of the mover 7 and the slider 6 on the slide, that is, the maximum stroke of the module. This design not only greatly improves the applicability and flexibility of the module, enabling it to easily cope with work objects of different sizes and changing working environments, but also effectively avoids the testing inconvenience and increased production cost caused by fixed stroke. In addition, the setting of the guide column 11 ensures the stability and accuracy of the nut plate 10 during movement, further improving the working efficiency and reliability of the module.
