Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a movable gear sleeve device with adjustable fixed distance. Background Art

[0002] For example, some conventional structural parts such as scraper frames, booms, and bulldozers usually have multiple sets of BOSS orifice plates for spacing and splicing. A certain spacing must be maintained between the BOSS orifice plates to facilitate subsequent milling. In the manufacturing process of existing products, after the BOSS orifice plates pass through the splicing axis, a semicircular sleeve of a fixed size is usually used to set the spacing on the splicing axis. This semicircular sleeve, due to its thin thickness, has a small fitting area with the BOSS surface when spacing, which often causes upper and lower dimensional deviations between the BOSS surfaces. After each positioning is completed, it is clamped between the two Boss surfaces, so it takes a lot of force to remove it, which is time-consuming and labor-intensive. In addition, the semicircular sleeve is a thin semicircular structure, such as Figure 6 and Figure 7 As shown, the wall thickness is relatively thin, and the wear caused by frequent use is relatively large. Long-term use will cause large dimensional deviations.

[0003] Therefore, there is an urgent need for a movable and adjustable distance gear sleeve device to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to overcome the problems in the background technology and to provide a movable and adjustable distance gear sleeve device, which can increase the fitting points and fitting area between the gear sleeve and the BOSS surface. When removing the gear sleeve, the gear sleeve can be easily removed by simply pulling the handle. The operation is simple and the wear is small. The size of the gear sleeve can be adjusted according to actual production conditions to avoid various disadvantages caused by the semi-circular gear sleeve.

[0005] In order to achieve the above-mentioned purpose of the utility model, the technical solution adopted by the utility model is specifically as follows: a movable and adjustable fixed-distance gear sleeve device, including a fixed inclined plane block and a movable inclined plane block, the movable inclined plane block is movably arranged on the fixed inclined plane block, the fixed inclined plane block is fitted with the side surface of the movable inclined plane block, and a plurality of adjusting screws are respectively arranged on the opposite sides of the fixed inclined plane block and the movable inclined plane block, and the ends of the adjusting screws will directly fit with the boss surface. Since the adjusting screws can adjust the length, the gear sleeve device can adjust the gear sleeve size according to actual production conditions; the lower sides of the fixed inclined plane block and the movable inclined plane block are both provided with bayonet sockets adapted to the splicing point axis, and a connecting mechanism is provided between the fixed inclined plane block and the movable inclined plane block, and the movable inclined plane block can slide upwardly relative to the fixed inclined plane block to reduce the gear distance size of the gear sleeve device;

[0006] The movable inclined plane block is provided with a transverse positioning mechanism, and the fixed inclined plane block is provided with a notch 1 that cooperates with the transverse positioning mechanism, and the transverse positioning mechanism can prevent the fixed inclined plane block and the movable inclined plane block from sliding relative to each other transversely;

[0007] The fixed inclined plane block is provided with a longitudinal positioning mechanism, and the longitudinal positioning mechanism can prevent longitudinal relative sliding between the movable inclined plane block and the fixed inclined plane block.

[0008] Furthermore, the lateral positioning mechanism includes a notch 2 arranged on the movable inclined plane block and a flat key block arranged in the notch 2. The flat key block and the notch 2 can be connected by screws. The notch 1 and the notch 2 together form a flat key slot. The flat key block is adapted to the flat key slot. When the fixed inclined plane block and the movable inclined plane block are installed, the flat key block is first installed in the notch 2. The movable inclined plane block and the fixed inclined plane block are fitted together and slide obliquely downward so that the protruding part of the flat key block is inserted into the notch 1. In this way, the flat key block is located in the notch 1 and the notch 2 at the same time. This can avoid lateral sliding between the fixed inclined plane block and the movable inclined plane block, and play a role of lateral limiting for the fixed inclined plane block and the movable inclined plane block.

[0009] Furthermore, the longitudinal positioning mechanism includes a clamping screw arranged at the upper end of the fixed inclined block, a pressure block is fixedly arranged on the clamping screw, and a limit plate is movably arranged on the clamping screw below the pressure block.

[0010] Furthermore, the limit plate is semicircular and is provided with a light hole. The clamping screw passes through the light hole and is threadedly connected to the upper end of the fixed inclined block. The limit plate can rotate freely around the clamping screw. During the installation process, the limit plate is rotated so that a part of the limit plate is located above the movable inclined block. Then, the clamping screw is rotated, and the clamping screw drives the pressure block to move downward. The pressure block can press the limit plate, and the limit plate is tightly attached to the upper side of the movable inclined block, so that the movable inclined block cannot move upward, thereby avoiding longitudinal sliding between the movable inclined block and the fixed inclined block, and playing a role of longitudinal limiting the fixed inclined block and the movable inclined block.

[0011] Furthermore, the fitting surface between the fixed bevel block and the movable bevel block is an inclined surface, the movable bevel block can move toward the top of the fixed bevel block, and the fitting surface is inclined toward one side of the fixed bevel block. After the movable bevel block slides upward at an angle, the total thickness between the movable bevel block and the fixed bevel block is reduced, so that the boss surfaces on both sides will not clamp the gear sleeve device, thereby facilitating the removal of the gear sleeve device from the splicing point shaft.

[0012] Furthermore, the connecting mechanism comprises a connecting bolt, an oblong hole provided on the fixed inclined plane block and a threaded hole provided on the movable inclined plane block, and the oblong hole and the threaded hole are arranged opposite to each other.

[0013] Furthermore, the oblong hole is elliptical and is longitudinally arranged on the fixed bevel block. The connecting bolt is connected to the threaded hole after passing through the oblong hole. Multiple connecting bolts can be arranged on each side. The arrangement of multiple connecting bolts can increase the contact points and contact area with the Boss surface, which is beneficial to improving positioning accuracy and reducing dimensional deviation. During disassembly, the movable bevel block is moved upward, and the movable bevel block drives the connecting bolt to move upward in the oblong hole. Since the fitting surface is an inclined surface, the total thickness of the movable bevel block and the fixed bevel block will be reduced after moving upward, that is, the total thickness of the gear sleeve device is reduced, and the connecting bolts on both sides of the gear sleeve device are loose in contact with the Boss surface. Therefore, the gear sleeve device can be directly removed from the splicing point shaft, which is simple to operate and will not cause wear.

[0014] Furthermore, the upper end of the bayonet is an arc structure and is compatible with the splicing point axis.

[0015] Furthermore, a movable handle is provided at the upper end of the movable inclined plane block, and the movable handle can be held and pulled upward to drive the movable inclined plane block to move upward along the fitting surface.

[0016] Furthermore, an extension base is provided at the bottom of the fixed inclined plane block, the movable inclined plane block is provided on the extension base, and the lower end of the movable inclined plane block abuts against the upper end of the extension base.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. Multiple adjusting screws are arranged on both sides of the gear sleeve device. When the distance is fixed, the ends of the multiple adjusting screws are in contact with the Boss surface. Compared with the semicircular gear sleeve with a traditional thin-film structure, the gear sleeve device increases the contact point and contact area with the Boss surface, which is beneficial to improve the positioning accuracy and reduce the size deviation. At the same time, the length of the adjusting screws on both sides can be adjusted, so the gear sleeve size can be adjusted according to the actual production situation, and the adaptability is wide.

[0019] 2. When removing the gear sleeve device, slide the movable inclined block upward along the fitting surface. The front and rear dimensions of the gear sleeve device will be reduced as a whole. In this way, the adjusting screw no longer contacts the Boss surface. Therefore, the gear sleeve device can be easily removed, saving time and effort. At the same time, it will not wear on the Boss surface when removing it, which is conducive to ensuring the size of the Boss board surface. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. Of course, the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] Example: Figure 1-Figure 5As shown, the present embodiment provides a movable adjustable fixed-distance gear sleeve device, comprising a fixed bevel block 1 and a movable bevel block 2, wherein the movable bevel block 2 is movably arranged on the fixed bevel block 1, the fixed bevel block 1 is fitted with the side surface of the movable bevel block 2, and a plurality of adjusting screws 3 are respectively arranged on the opposite sides of the fixed bevel block 1 and the movable bevel block 2, and the ends of the adjusting screws will directly fit with the boss surface. Since the adjusting screws can be adjusted in length, the gear sleeve device can adjust the gear sleeve size according to actual production conditions; the lower sides of the fixed bevel block 1 and the movable bevel block 2 are both provided with a bayonet 5 adapted to the splicing point axis, the upper end of the bayonet 5 is a circular arc structure, and is adapted to the splicing point axis, and the fixed bevel block 1 A connecting mechanism is provided between the movable inclined plane block 2, and the movable inclined plane block 2 can slide upwardly relative to the fixed inclined plane block 1 to reduce the gear spacing size of the gear sleeve device; a movable handle 15 is provided at the upper end of the movable inclined plane block 2, and the movable handle 15 is held and pulled upward to drive the movable inclined plane block 2 to move upward along the fitting surface; a transverse positioning mechanism is provided on the movable inclined plane block 2, and a notch 6 cooperating with the transverse positioning mechanism is provided on the fixed inclined plane block 1, and the transverse positioning mechanism can prevent the fixed inclined plane block 1 and the movable inclined plane block 2 from sliding relative to each other ...

[0031] The lateral positioning mechanism includes a notch 27 arranged on the movable inclined plane block 2 and a flat key block 8 arranged in the notch 27. The flat key block 8 and the notch 27 can be connected by screws. The notch 16 and the notch 27 together form a flat key groove. The flat key block 8 is adapted to the flat key groove. When the fixed inclined plane block 1 and the movable inclined plane block 2 are installed, the flat key block 8 is first installed in the notch 27. The movable inclined plane block 2 and the fixed inclined plane block 1 are fitted together and slide obliquely downward so that the protruding part of the flat key block 8 is inserted into the notch 16. In this way, the flat key block 8 is located in the notch 16 and the notch 27 at the same time. In this way, the lateral sliding between the fixed inclined plane block 1 and the movable inclined plane block 2 can be avoided, and the fixed inclined plane block 1 and the movable inclined plane block 2 can be played a role of lateral limitation.

[0032] The longitudinal positioning mechanism includes a clamping screw 9 arranged at the upper end of the fixed inclined plane block 1, a clamping block 10 is fixedly arranged on the clamping screw 9, and a limit plate 11 is movably arranged on the clamping screw 9 located below the clamping block 10. The limit plate 11 is semicircular, and a light hole is arranged on the limit plate 11. The clamping screw 9 passes through the light hole, and the limit plate 11 can rotate freely around the clamping screw 9. During the installation process, the limit plate 11 is rotated so that a part of the limit plate 11 is located above the movable inclined plane block 2, and then when the clamping screw 9 is rotated, the clamping screw 9 drives the clamping block 10 to move downward, and the clamping block 10 can press the limit plate 11, and the limit plate 11 is close to the upper side of the movable inclined plane block 2, so that the movable inclined plane block 2 cannot move upward, which can avoid the longitudinal sliding between the movable inclined plane block 2 and the fixed inclined plane block 1, and play a role of longitudinal limiting the fixed inclined plane block 1 and the movable inclined plane block 2.

[0033] The fitting surface between the fixed bevel block 1 and the movable bevel block 2 is an inclined surface. The movable bevel block 2 can move toward the top of the fixed bevel block 1. The fitting surface is inclined toward one side of the fixed bevel block 1. After the movable bevel block 2 slides upward at an angle, the total thickness between the movable bevel block 2 and the fixed bevel block 1 is reduced, so that the boss surfaces on both sides will not clamp the gear sleeve device, thereby facilitating the removal of the gear sleeve device from the splicing point shaft.

[0034] The connecting mechanism comprises a connecting bolt 12 , an oblong hole 13 provided on the fixed inclined plane block 1 and a threaded hole 14 provided on the movable inclined plane block 2 , and the oblong hole 13 and the threaded hole 14 are arranged opposite to each other.

[0035] The oblong hole 13 is elliptical and is longitudinally arranged on the fixed bevel block 1. The connecting bolt 12 passes through the oblong hole 13 and is connected to the threaded hole 14. Multiple connecting bolts 12 can be arranged on each side. The arrangement of multiple connecting bolts 12 can increase the contact points and contact area with the Boss surface, which is beneficial to improve positioning accuracy and reduce dimensional deviation. During disassembly, the movable bevel block 2 is moved upward, and the movable bevel block 2 drives the connecting bolt 12 to move upward in the oblong hole 13. Since the fitting surface is an inclined surface, the total thickness of the movable bevel block 2 and the fixed bevel block 1 will be reduced after moving upward, that is, the total thickness of the gear sleeve device is reduced, and the connecting bolts 12 on both sides of the gear sleeve device are loose in contact with the Boss surface. Therefore, the gear sleeve device can be directly removed from the splicing point shaft, which is simple to operate and will not cause wear.

[0036] An extension base 4 is provided at the bottom of the fixed inclined plane block 1 , and the movable inclined plane block 2 is provided on the extension base 4 , and the lower end of the movable inclined plane block 2 abuts against the upper end of the extension base 4 .

[0037] When in use, first install the stop sleeve device, install the flat key block 8 in the notch 2 7 by screws, after installation, slide the movable inclined plane block 2 downward along the fitting surface, so that the protruding part of the flat key block 8 is embedded in the notch 1 6, so that the lateral limit of the fixed inclined plane block 1 and the movable inclined plane block 2 can be completed, and then the limit plate 11 is rotated to make it located on the upper side of the movable inclined plane block 2, and the pressing screw 9 is rotated forward, and the pressing screw 9 drives the pressing block 10 to move downward, and the pressing block 10 presses the limit plate 11, so that the longitudinal limit of the fixed inclined plane block 1 and the movable inclined plane block 2 can be completed; then the connecting bolt 12 is passed through the oblong hole 13 and connected with the threaded hole 14;

[0038] Rotate the adjusting screws 3 on both sides to determine the fixed distance size, then place the gear sleeve device on the splicing point axis, and match the bayonet 5 with the splicing point axis, so that the end of the adjusting screw 3 on one side of the gear sleeve device fits with the side of the welded Boss plate, take another Boss plate and place it on the splicing point axis, fit the Boss plate with the other side of the gear sleeve device, and then perform splicing welding on the Boss plate;

[0039] After the points are assembled, the gear sleeve device needs to be removed. First, rotate the adjusting screw 3 in the opposite direction so that the limit plate 11 no longer restricts the movable inclined surface block 2. Hold the movable handle 15 and pull the movable inclined surface block 2 upward. The movable inclined surface block will slide upward along the fitting surface, and the connecting screw will also move upward in the oblong hole 13. After the movement, since the total front and rear dimensions of the gear adjustment device are reduced, the end of the adjusting screw 3 will no longer contact the Boss surface. Therefore, the gear sleeve device can be directly lifted out without wear. The gear sleeve device only needs to be installed once and can be used directly later.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
