Description

Technical Field

[0001] This application relates to the field of end cap processing technology, and in particular to a trimming and grinding fixture and a trimming and grinding device. Background Technology

[0002] Tank containers, also known as tank boxes, are increasingly used in various storage and transportation industries. As a result, the safety of operations on top of tank containers has become a major concern for on-site loading and unloading personnel.

[0003] The end caps of tank containers can be round or non-circular, such as square-round, elliptical, or oblong. The edges of these end caps require beveling and grinding. Round end caps, due to their fixed diameter, can be ground using fixed fixtures, such as placing them on a rotating platform and mounting a grinding machine on a fixed support rod. However, non-circular end caps often have varying diameters, making this method unsuitable. Currently, workers must manually grind them with a handheld grinding machine, resulting in high labor intensity, low production efficiency, and a low yield. Therefore, a new technical solution is urgently needed to address at least one of these technical problems. Summary of the Invention

[0004] In view of the above shortcomings, one objective of this application is to provide a tooling for edge trimming and grinding, which facilitates grinding operations for workers. Another objective of this application is to provide an edge trimming and grinding device suitable for various types of end caps, which provides good edge trimming and grinding uniformity, reduces labor intensity, improves production efficiency, and increases yield.

[0005] To achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted in this application is as follows:

[0006] A tooling for edge trimming and grinding, characterized in that it includes a support frame and a base plate, the base plate being rotatably mounted on the support frame, at least one slide rail being slidably mounted on the upper side of the base plate, the slide rail being connected to a bracket, and the bracket being provided with a follower part that moves with the workpiece, the follower part being rotatably connected to the bracket.

[0007] As a preferred technical solution, the support frame is rotatably provided with a rotating shaft at one end near the workpiece, and the base plate is fixedly connected to the rotating shaft.

[0008] As a preferred technical solution, the bracket includes a lower support plate, a hand handle fixedly disposed on the upper side of the lower support plate, and a shaft vertically disposed on the hand handle. The follower part is rotatably sleeved on the shaft, and the lower support plate is fixedly connected to the slide rail.

[0009] As a preferred technical solution, the handheld rod is detachably fitted with an adjusting sleeve, and the shaft is fixedly connected to the adjusting sleeve.

[0010] As a preferred technical solution, a limiting frame is provided at the end of the support frame away from the workpiece. The limiting frame includes a limiting bottom rod fixedly disposed on the support frame, a connecting vertical rod fixedly disposed on the limiting bottom rod, and a limiting upper rod fixedly disposed on the upper end of the connecting vertical rod.

[0011] As a preferred technical solution, a mounting rod is vertically provided at the end of the shaft away from the hand handle, and the mounting rod is provided with a limiting part.

[0012] As a preferred technical solution, the number of slide rails is two, the two slide rails are symmetrically arranged, and two guide blocks are fixedly and symmetrically arranged on the upper side of the base plate, and the slide rails are slidably inserted into the guide blocks.

[0013] As a preferred technical solution, the follower part is a roller shaft, and the limiting part is a bearing.

[0014] This application also provides an edge trimming and grinding device, characterized in that it includes the edge trimming and grinding fixture and a grinding machine, wherein the grinding machine is detachably mounted on the slide rail or the bracket.

[0015] As a preferred technical solution, the grinding disc of the grinding machine abuts against the outer periphery of the upper edge of the workpiece or against the upper edge of the workpiece.

[0016] Compared with traditional technical solutions, the beneficial effects of this application are:

[0017] 1) During grinding, the worker holds the bracket and pushes the grinding machine to the edge of the end cap. The grinding machine grinds the edge of the end cap. If the end cap is not circular, due to the large variation in the diameter of the end cap, when the end cap rotates from a small diameter to a large diameter, it will push the grinding machine backward. At this time, the worker only needs to push the grinding machine forward with a little force. The grinding machine can move forward and backward through the slide rail. The grinding machine is always located on the outer periphery of the edge of the end cap. This edge grinding fixture can be used for end caps of various shapes and has good versatility.

[0018] 2) With the head opening facing upwards, the follower part rests on the edge of the head. If the upper edge of the head is not flat, during rotation, the lever structure formed by the base plate and the rotating shaft can ensure that the follower part always rests on the upper edge of the head, so that the grinder can always fit against the upper edge of the head and be in a suitable grinding position, ensuring that the grinding position of the grinder remains accurate.

[0019] 3) Adjust the height of the follower part by adjusting the adjusting sleeve to meet different grinding bevel angle requirements;

[0020] 4) During operation, the operator may move the grinding machine excessively. When excessive movement occurs, the limiting part hooks onto the inner wall of the end cap to prevent the grinding machine from moving excessively. Furthermore, the limiting part is a bearing. After the end cap and the limiting part come into contact, the bearing can rotate to prevent damage to the inner wall of the end cap.

[0021] 5) The grinding machine can be installed in a position that needs to be adjusted. The grinding machine can grind the upper edge or the outer periphery of the upper edge of the end cap. Attached Figure Description

Detailed Implementation

[0029] The present application will now be further described with reference to the accompanying drawings.

[0030] In the accompanying drawings of the embodiments of this application, the same or similar reference numerals correspond to the same or similar components. In the description of this application, it should be understood that if terms such as "top", "bottom", "left", "right", "front", "rear", "inner", "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this application, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0031] Please refer to Figures 1-6 An embodiment of this application provides a beveling and grinding fixture, including a support frame 1 and a base plate 2. The base plate 2 is rotatably mounted on the support frame 1. At least one slide rail 3 is slidably mounted on the upper side of the base plate 2. The slide rail 3 is connected to a bracket 4. The bracket 4 is provided with a follower part 405 that moves with the workpiece. The follower part 405 is rotatably connected to the bracket 4. When the workpiece is a head 10, a grinding machine 9 is detachably mounted on the beveling and grinding fixture, and the slide rail 3 can move along the base plate. 2. Sliding: During grinding, the worker holds the bracket 4 and pushes the grinding machine 9 to the edge of the end cap 10. The follower 405 rests on the upper edge of the end cap 10. The rotating platform rotates, and the grinding machine 9 performs edge trimming and grinding on the upper edge of the end cap 10. If the end cap 10 is not circular, due to the change in its diameter, the end cap 10 will push the grinding machine 9 and drive the bracket 4 to move backward during the grinding process, ensuring that the grinding machine 9 is always in the position of the outer periphery of the upper edge of the end cap 10. In this way, the edge trimming and grinding fixture can be applied to end caps of various shapes.

[0032] When the end cap 10 is installed on the rotating platform, the opening of the end cap 10 faces upwards, making it difficult to keep the end cap 10 level. It takes a lot of time to level it, and it is impossible to ensure that the grinding machine 9 is in the right position during grinding. The follower part 405 rests on the upper edge of the end cap 10. If the upper edge of the end cap 10 is not level, the follower part 405 will swing up and down during rotation. The follower part 405 will drive the entire support 4 to swing up and down, which in turn will drive the grinding machine 9 set on the support 4 to swing up and down. This ensures that the grinding machine 9 can always fit against the upper edge of the end cap 10 and be in the right grinding position, thereby improving production efficiency, reducing labor intensity, and increasing the yield.

[0033] Specifically, the follower part 405 is a roller with a smooth outer circumferential surface to prevent damage to the end cap 10.

[0034] like Figures 1-6As shown, the support frame 1 has a rotating shaft 6 rotatably mounted near the workpiece end. The base plate 2 is fixedly connected to the rotating shaft 6. Specifically, there are two rotating shafts 6, which are symmetrically arranged. The lower front part of the base plate 2 is fixedly connected to the rotating shaft 6 to form a fulcrum. Utilizing the lever principle, when the upper edge of the end cap 10 pushes the follower part 405 to move upward, the follower part 405 drives the bracket 4 to swing upward, which in turn drives the grinding machine 9 mounted on the lower support plate 401 to swing upward. Due to the lever structure formed by the base plate 2 and the rotating shaft 6, the base plate 2 will rotate around the rotating shaft 6. When the upper edge of the end cap 10 returns to its original position, the bracket 4 and the grinding machine 9 will swing downward due to gravity, causing the follower part 5 to swing downward, so that the follower part 405 is always positioned on the upper edge of the end cap 10 to ensure that the grinding position of the grinding machine 9 remains accurate.

[0035] Specifically, such as Figures 1-6 As shown, the support frame 1 includes a first front support vertical rod 101, a second front support vertical rod 102, a first rear support vertical rod 103, and a second support vertical rod arranged vertically. A first support longitudinal rod 105 extending longitudinally is fixedly arranged between the first front support vertical rod 101 and the first rear support vertical rod 103. A second support longitudinal rod 106 extending longitudinally is fixedly arranged between the first rear support vertical rod 103 and the second rear support vertical rod 104. A first support transverse rod extending laterally is fixedly arranged between the first front support vertical rod 101 and the second front support vertical rod 102. 107. A second support crossbar 108 extending laterally is fixedly arranged between the first rear support vertical bar 103 and the second rear support vertical bar 104. A support 109 is respectively arranged on the inner side of the first front support vertical bar 101 and the second front support vertical bar 102. A rotating bearing 601 is installed in the support 109. A rotating shaft 6 is inserted into the rotating bearing 601 and can rotate. The support 109 is located above the base plate 2. The support 109 includes two symmetrically arranged inverted L-shaped side plates 1091. The rotating bearing 601 is installed between the two side plates 1091.

[0036] like Figures 1-6 As shown, the support 4 includes a lower support plate 401, a hand handle 402 fixedly mounted on the upper side of the lower support plate 401, and a shaft 403 vertically mounted on the hand handle 402. The follower part 405 is rotatably sleeved on the shaft 403. The lower support plate 401 is fixedly connected to the slide rail 3. The hand handle 402 is easy for the operator to hold and push the support 4 toward the outer periphery of the end cap 10. Furthermore, the hand handle 402 is made into a sleeve structure, that is, an adjusting sleeve 406 is fitted on the hand handle 402. The shaft 403 is fixedly connected to the adjusting sleeve 406. The adjusting sleeve 406 is provided with a threaded hole, and a bolt is screwed into the threaded hole. In this way, the follower part 405 can adjust its height. During processing, the follower part 405 can be adjusted to any height and placed on the upper edge of the end cap 10 to adjust the grinding angle to meet different bevel angle requirements.

[0037] like Figures 1-6 As shown, a limiting frame 5 is provided at the end of the support frame 1 away from the workpiece. Specifically, the limiting frame 5 includes a limiting bottom rod 501 fixedly installed on the support frame 1, a connecting vertical rod 502 fixedly installed vertically on the limiting bottom rod 501, and a limiting upper rod 503 fixedly installed vertically on the upper end of the connecting vertical rod 502. Specifically, the limiting bottom rod 501 is fixedly connected to the second support cross rod 108. Since the base plate 2 drives the slide rail 3 to swing up and down, the limiting upper rod 503 abuts against the base plate 2 to prevent the base plate 2 from swinging excessively. A stop bar 8 is provided across the two slide rails 3. When the slide rail 3 is in its original position, the stop bar 8 abuts against the limiting upper rod 503 to form a limit. Especially when installing the grinding machine 9, since the grinding machine 9 is relatively heavy, the base plate 2 and the rear end of the slide rail are prone to tilting upwards during installation. The upward tilting height of the rear end of the slide rail 3 is limited by the stop bar 8 abutting against the limiting upper rod 503.

[0038] like Figures 1-6 As shown, a mounting rod 404 is vertically arranged at the end of the shaft 403 away from the hand handle 402. The mounting rod 404 is rotatably fitted with a limiting part 7. During operation, the operator may move the grinder 9 excessively. When excessive movement occurs, the limiting part 7 hooks onto the inner wall of the end cap 10 to prevent the grinder 9 from displacing excessively. Specifically, the limiting part 7 is a rolling bearing. After the end cap 10 abuts against the limiting part 7, the bearing can rotate to prevent damage to the inner wall of the end cap 10.

[0039] like Figures 1-6 As shown, there are two slide rails 3, which are symmetrically arranged. Two guide blocks 301 are fixedly and symmetrically arranged on the upper side of the base plate 2. The slide rails 3 can be slidably inserted into the guide blocks 301. The slide rails 3 slide along the guide blocks 301, which has a good guiding effect and more stable movement.

[0040] Please see Figures 1-6 This application also provides an edge trimming and grinding device, including the aforementioned edge trimming and grinding fixture and a grinding machine 9. The grinding machine 9 is detachably mounted on the slide rail 3 or the lower support plate 401. The slide rail 3 is provided with threaded holes, and the lower support plate 1 is provided with corresponding threaded holes. The grinding machine 9 is connected to the slide rail 3 and the lower support plate 401 by bolts, or the threaded holes are directly provided on the lower support plate, and the grinding machine 9 is directly connected to the lower support plate 401 by bolts.

[0041] like Figures 1-6 As shown, the grinding disc 901 of the grinding machine 9 abuts against the outer periphery of the upper edge of the workpiece or against the upper edge of the workpiece. The grinding machine 9 can adjust its installation position as needed, and can grind the upper edge or the outer periphery of the upper edge of the end cap 10.

[0042] The working process of a preferred embodiment of the edge-trimming and grinding device provided in this application is as follows:

[0043] When grinding the outer periphery of the upper edge of a non-circular end cap 10, the end cap 10 is installed on a rotating platform with its opening facing upwards. The operator holds the handle 402 and moves the grinder 9 towards the outer periphery of the upper edge of the end cap 10. The height of the roller is adjusted according to the different bevel angles being ground. The rotating platform rotates the end cap 10. The operator holds the handle 402 forward and moves the lower support plate 401 towards the outer periphery of the upper edge of the end cap 10. The slide rail 3 can slide along the guide block 301, thereby moving the grinder 9 towards the outer periphery of the upper edge of the end cap 10. The roller rests on the upper edge of the end cap 10. When the upper edge of the end cap 10 is not horizontal, the roller swings up and down with the upper edge of the end cap 10 to ensure the grinding is smooth. The mill 9 continuously grinds the outer periphery of the upper edge of the end cap 10. Due to the large variation in the diameter of the end cap 10, when the end cap 10 rotates from a small diameter to a large diameter, it will push the mill 9 backward. At this time, the operator needs to push the mill 9 forward with a little force to ensure that the mill 9 is always in contact with the outer periphery of the upper edge of the end cap 10, with the roller shaft in contact with the upper edge of the end cap 10. The rotation of the end cap 10 causes the roller shaft to rotate, preventing damage to the end cap 10. At the same time, when the angle requirements of the bevel 1001 are different, the height of the roller shaft is adjusted so that the angle between the roller shaft and the upper edge of the end cap 10 is different during grinding, thereby changing the grinding angle and thus meeting the different bevel 1001 angle requirements.

[0044] On-site timing showed that it takes 10 minutes for a worker to grind a non-circular end cap 10 with a handheld grinder 9. However, after using the edge-cutting and grinding device of this application, it only takes 3 minutes to grind an end cap 10, saving 7 minutes per end cap 10. A total of 1,420 end caps 10 were produced in 6 months, saving 1,420 * 7 minutes = 165 hours of labor time. This shortened the production cycle, greatly reduced the labor intensity of the workers, improved the production quality, and made the end cap 10 more compatible with the cylinder.
