Description

Technical Field

[0001] This utility model relates to the field of T-screw grinding technology, specifically a grinding device for T-screw production. Background Technology

[0002] Currently, grinding is a crucial step in the production of T-screws, as it directly affects the surface quality and mechanical properties of the screws. However, traditional T-screw grinding methods often have many problems, which to some extent restrict the improvement of production efficiency and the guarantee of product quality.

[0003] Traditional grinding equipment typically uses a single-direction grinding method. While this method is simple and direct, it often fails to ensure a uniform grinding effect on the screw surface. Especially in complex areas such as the edges and grooves of the screw, traditional grinding methods often struggle to reach them, leading to insufficient or excessive grinding in these areas, thus affecting the overall appearance and performance of the screw.

[0004] Secondly, some existing grinding equipment lacks an effective screw fixing and transmission mechanism during the grinding process. During grinding, screws are prone to displacement or falling off due to vibration or insufficient friction. This not only increases the difficulty of operation but may also cause injury to equipment and personnel. At the same time, the lack of an effective transmission mechanism makes it difficult to control the grinding speed of screws, further affecting grinding efficiency and product quality.

[0005] Therefore, we propose a grinding device for producing T-type screws, which grinds the screws from all directions and achieves intermittent clamping and transmission of the screws through mechanisms such as eccentric discs and reciprocating rods, thereby effectively solving the problems of poor uniformity and unstable fixation in traditional grinding methods. Utility Model Content

[0006] The purpose of this invention is to provide a grinding device for the production of T-screws, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for producing T-shaped screws, comprising a guide frame, a screw screening machine fixedly installed on one side of the guide frame, a grinding assembly installed at the bottom of the other side of the guide frame, a base installed on the other side of the grinding assembly, an eccentric disk rotatably installed in the middle of the base, a reciprocating rod rotatably installed on the outer side of the eccentric disk, and a blocking mechanism installed at the top of the reciprocating rod, wherein multiple sets of equally spaced screws distributed on the guide frame are blocked by the blocking mechanism.

[0008] Optionally, the blocking mechanism includes a piston cylinder fixedly installed on the top of the reciprocating rod, a pressing rod movably installed inside the piston cylinder, a fixing ring fixedly installed on the middle of the outer side of the pressing rod, and a spring fixedly installed on the side wall of the fixing ring. The other side of the spring is fixedly installed on the side wall of the piston cylinder, and the bottom of the pressing rod corresponds to the top of the screw.

[0009] By adopting the above technical solution, the screws can be tightened intermittently.

[0010] Optionally, a pressure plate is installed on the top of the flow guide, the distance between the pressure plate and the flow guide is greater than the thickness of the screw head, and a limit hole is opened on one side of the pressure plate, the limit hole being movably connected to a limit rod.

[0011] By adopting the above technical solution, the screw can be limited.

[0012] Optionally, a limiting cylinder is fixedly installed on one side of the bottom of the flow guide frame via a bracket, and the limiting cylinder is movably connected to the reciprocating rod.

[0013] By adopting the above technical solution, the reciprocating rod can be limited.

[0014] Optionally, the polishing assembly includes three sets of equidistant first polishing rollers installed on one side of the bottom of the guide frame, three sets of equidistant second polishing rollers installed on the other side of the bottom of the guide frame, a transmission belt driven on the shaft of each of the two adjacent sets of first polishing rollers, and gears installed at the bottom of each set of first and second polishing rollers. The gears distributed at the bottom of the first and second polishing rollers mesh, and the first and second polishing rollers are respectively distributed on both sides of the screw.

[0015] By adopting the above technical solution, screws can be polished efficiently.

[0016] Optionally, the bottom of the first grinding roller on one side is connected to the drive end of the first motor, and a second motor is fixedly installed in the middle of the other side of the base. The drive output end of the second motor is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed to the central shaft of the eccentric disk.

[0017] By adopting the above technical solution, the grinding roller and the eccentric disc can be driven separately.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application drives a second motor to rotate an eccentric disk, which in turn drives a reciprocating rod to move up and down. Since the other end of the reciprocating rod is equipped with a piston cylinder, a pressing rod, a fixing ring, and a spring, when the reciprocating rod moves downward, it will press the spring at the bottom of the piston cylinder. The spring under pressure will press the pressing rod, causing the bottom of the pressing rod to press the screw that is being driven, thus stopping the screw drive. The screw is then ground for a long time by multiple sets of first and second grinding rollers, greatly improving the grinding effect of the screw. Conversely, when the reciprocating rod moves upward, the pressing rod will move upward synchronously with the reciprocating rod, releasing the pressed screw and allowing a large number of screws to continue to be driven on the guide frame.

[0020] After the operator drives the first motor, it will drive the first grinding roller on one side to rotate. Since the two adjacent sets of first grinding rollers are connected by a transmission belt, they can drive the three sets of first grinding rollers to rotate in the same direction synchronously. Due to the meshing of the gears distributed at the bottom of the first and second grinding rollers, the three sets of second grinding rollers rotate synchronously in opposite directions, so that each set of first and second grinding rollers rotates synchronously in the direction of the screw, which efficiently grinds both sides of the screw and greatly improves the grinding efficiency.

[0026] Please see Figure 1-3This utility model provides a technical solution: a grinding device for producing T-shaped screws, including a guide frame 1, a screw screening machine 11 fixedly installed on one side of the guide frame 1, a grinding component installed at the bottom of the other side of the guide frame 1, a base installed on the other side of the grinding component, an eccentric disk 2 rotatably installed in the middle of the base, a reciprocating rod 21 rotatably installed on the outer side of the eccentric disk 2, and a blocking mechanism installed on the top of the reciprocating rod 21. Multiple sets of screws distributed at equal intervals on the guide frame 1 are blocked by the blocking mechanism. The blocking mechanism includes a piston cylinder 22 fixedly installed on the top of the reciprocating rod 21, a pressing rod 23 movably installed inside the piston cylinder 22, a fixing ring 24 fixedly installed in the middle of the outer side of the pressing rod 23, and a spring 25 fixedly installed on the side wall of the fixing ring 24. The other side of the spring 25 is fixedly installed on the side wall of the piston cylinder 22. The bottom of the pressing rod 23 corresponds to the top of the screw, and can intermittently press the screw.

[0027] The second motor drives the eccentric disk 2 to rotate, which in turn drives the reciprocating rod 21 to move up and down repeatedly. Since the other end of the reciprocating rod 21 is equipped with a piston cylinder 22, a pressing rod 23, a fixing ring 24, and a spring 25, when the reciprocating rod 21 moves downward, it will press the spring 25 at the bottom of the piston cylinder 22. The spring 25 under pressure will press the pressing rod 23, causing the bottom of the pressing rod 23 to press down on the screw that is being driven, thus stopping the screw drive. The screw is then ground for a long time by multiple sets of first grinding rollers 3 and second grinding rollers 31, greatly improving the screw grinding effect. Conversely, when the reciprocating rod 21 moves upward, the pressing rod 23 will move upward synchronously with the reciprocating rod 21, releasing the pressed screw and allowing a large number of screws to continue to be driven on the guide frame 1.

[0028] In this technical solution, the grinding assembly includes three sets of equidistant first grinding rollers 3 installed on one side of the bottom of the guide frame 1, three sets of equidistant second grinding rollers 31 installed on the other side of the bottom of the guide frame 1, a transmission belt driven on the central shaft of each of the two adjacent sets of first grinding rollers 3, and gears 32 installed at the bottom of each set of first grinding rollers 3 and second grinding rollers 31. The gears 32 distributed at the bottom of the first grinding rollers 3 and second grinding rollers 31 mesh. The first grinding rollers 3 and second grinding rollers 31 are respectively distributed on both sides of the screw, which can efficiently grind the screw. The bottom of the first grinding roller 3 on one side is connected to the drive end of the first motor. A second motor is fixedly installed in the middle of the other side of the base. The drive output end of the second motor is driven and connected to the transmission shaft. The other end of the transmission shaft is fixedly installed on the central shaft of the eccentric disk 2, which can drive the grinding rollers and the eccentric disk 2 respectively.

[0029] After the operator drives the first motor, it will drive the first grinding roller 3 located on one side to rotate. Since the two adjacent sets of first grinding rollers 3 are connected by transmission belt, they can drive the three sets of first grinding rollers 3 to rotate in the same direction synchronously. Due to the meshing of the gears 32 distributed at the bottom of the first grinding roller 3 and the second grinding roller 31, the three sets of second grinding rollers 31 rotate synchronously in opposite directions, so that each set of first grinding roller 3 and second grinding roller 31 rotates synchronously in the direction of the screw, which efficiently grinds both sides of the screw and greatly improves the grinding efficiency.

[0030] In this technical solution, a limiting cylinder 26 is fixedly installed on one side of the bottom of the flow guide 1 by a bracket. The limiting cylinder 26 is movably connected to the reciprocating rod 21, which can limit the reciprocating rod 21.

[0031] When the operator drives the second motor to rotate the eccentric disk 2, the limiting cylinder 26, which is movably installed on the outside of the reciprocating rod 21, can effectively limit the reciprocating rod 21, ensuring that the eccentric disk 2 will drive the reciprocating rod 21 to move back and forth up and down.

[0032] In this technical solution, a pressure plate 12 is installed on the top of the flow guide 1. The distance between the pressure plate 12 and the flow guide 1 is greater than the thickness of the screw head. A limit hole 13 is opened on one side of the pressure plate 12. The limit hole 13 is movably connected to the limit rod, which can limit the screw.

[0033] The pressure plate 12 installed on the top of the guide frame 1 can limit the screws driven on the guide frame 1, so as to prevent the screws from being lifted off the guide frame 1 and falling off when the grinding roller is grinding.

[0034] In use, a large number of screws are first conveyed by the screw sorting machine 11 and guided one by one to the guide frame 1. With the vibration motor installed in the screw sorting machine 11 and the inclined guide frame 1, the screws can be conveyed into the grinding assembly. Multiple sets of first grinding rollers 3 and second grinding rollers 31 rotate synchronously in the direction of the screws, which not only grinds the surface of the screws, but also pushes the screws to move on the guide frame 1. At the same time, the second motor drives the eccentric disk 2 to rotate, which in turn drives the reciprocating rod 21 to move up and down. Since the other end of the reciprocating rod 21 is equipped with a piston cylinder 22, a pressing rod 23, a fixing ring 24, and a spring 25, when the reciprocating rod 21 moves downward, it will press the spring 25 at the bottom of the piston cylinder 22. The spring 25 under pressure will press the pressing rod 23, so that the bottom of the pressing rod 23 presses against the positive... When the screw is in motion, the screw transmission can be stopped, and it will be polished for a long time by multiple sets of first grinding rollers 3 and second grinding rollers 31, which greatly improves the polishing effect of the screw. Conversely, when the reciprocating rod 21 moves upward, the pressing rod 23 will move upward in sync with the reciprocating rod 21, releasing the pressed screw and allowing a large number of screws to continue to be transmitted on the guide frame 1. At the same time, after the operator drives the first motor, it will drive the first grinding roller 3 located on one side to rotate. Since the two adjacent sets of first grinding rollers 3 are connected by transmission belt, they can drive the three sets of first grinding rollers 3 to rotate in the same direction in sync. Due to the meshing of the gears 32 distributed at the bottom of the first grinding rollers 3 and second grinding rollers 31, the three sets of second grinding rollers 31 rotate in opposite directions in sync, so that each set of first grinding rollers 3 and second grinding rollers 31 rotates in the direction of the screw in sync, which efficiently polishes both sides of the screw and greatly improves the polishing efficiency.
