Description

Technical Field

[0001] The present application relates to the technical field of end cap processing, and in particular to an edge chopping and grinding tool and an edge chopping and grinding device. Background Art

[0002] Tank containers are also known as tank boxes. As tank boxes are increasingly used in various storage and transportation industries, the safety of top operations of tank boxes has become a matter of great concern to operators who load and unload goods on site.

[0003] The ends of the tank containers are round or non-round, such as square, oval, oblong, etc. The edges of the ends need to be chamfered and polished. Since the diameter of the round ends is fixed, fixed tooling can be used for polishing, such as placing the round ends on a rotating platform and using a fixed support rod to install a grinder for polishing. However, the diameter of non-round ends often varies greatly, and the above method cannot be used for polishing. Currently, the staff can only use a handheld grinder for polishing, which is labor-intensive, low in production efficiency, and low in yield. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the invention

[0004] In view of the above shortcomings, one purpose of the present application is to provide a grinding tool to facilitate the grinding work of the staff. Another purpose of the present application is to provide a grinding device suitable for a variety of heads, with good grinding uniformity, reduced labor intensity, improved production efficiency, and increased yield rate.

[0005] In order to achieve the above technical objectives and meet the above technical requirements, the technical solution adopted in this application is: A chamfering and grinding tool, characterized in that it includes a support frame and a base plate, wherein the base plate is rotatably arranged on the support frame, at least one slide rail is slidably arranged on the upper side of the base plate, the slide rail is connected to a bracket, the bracket is provided with a follower part that moves with the workpiece, and the follower part is rotatably connected to the bracket.

[0006] As a preferred technical solution, a rotating shaft is rotatably provided at one end of the support frame close to the workpiece, and the base plate is fixedly connected to the rotating shaft.

[0007] As a preferred technical solution, the bracket includes a lower support plate, a hand-held rod fixedly arranged on the upper side of the lower support plate, and an axis rod vertically arranged on the hand-held rod. The follower part can be rotatably mounted on the axis rod, and the lower support plate is fixedly connected to the slide rail.

[0008] As a preferred technical solution, the hand-held rod is detachably provided with an adjusting sleeve, and the shaft rod is fixedly connected to the adjusting sleeve.

[0009] As a preferred technical solution, a limiting frame is provided at one end of the support frame away from the workpiece, and the limiting frame includes a limiting bottom rod fixedly arranged on the support frame, a connecting vertical rod vertically fixedly arranged on the limiting bottom rod, and a limiting upper rod vertically fixedly arranged on the upper end of the connecting vertical rod.

[0010] As a preferred technical solution, a mounting rod is vertically arranged at one end of the shaft rod away from the hand-held rod, and the mounting rod is provided with a limiting portion.

[0011] As a preferred technical solution, the number of the slide rails is two, the two slide rails are symmetrically arranged, two guide blocks are fixedly and symmetrically arranged on the upper side of the bottom plate, and the slide rails can be slidably inserted into the guide blocks.

[0012] As a preferred technical solution, the follower part is a roller shaft, and the limiting part is a bearing.

[0013] The present application also provides an edge chopping and grinding device, characterized in that it comprises the edge chopping and grinding tooling and a grinder, and the grinder can be detachably arranged on the slide rail or the lower support plate.

[0014] As a preferred technical solution, the grinding disc of the grinder abuts against the outer peripheral side of the upper edge of the workpiece or abuts against the upper edge of the workpiece.

[0015] Compared with the traditional technical solution, the beneficial effects of this application are: 1) During grinding, the staff holds the bracket and pushes the grinder to the edge of the head. The grinder grinds the upper edge of the head. If the head is non-circular, due to the large change in the diameter of the head, when the head rotates from a small diameter to a large diameter, the grinder will be pushed backward. At this time, the staff only needs to push the grinder forward with a little force, and the grinder can move forward and backward through the slide rail, and the grinder is always on the outer peripheral side of the upper edge of the head. In this way, the edge grinding tooling can be applied to heads of various shapes and has good versatility. 2) The opening of the head is facing upwards, and the follower is placed on the edge of the head. If the upper edge of the head is uneven, during the rotation process, the lever structure formed by the bottom plate and the rotating shaft can make the follower always placed on the upper edge of the head, so that the grinder can always fit on the upper edge of the head and be in the appropriate grinding position, ensuring that the grinding position of the grinder remains accurate; 3) Adjust the height of the follower by adjusting the sleeve to meet different grinding groove angle requirements; 4) During operation, the staff may move the grinder excessively. When the grinder moves excessively, the limiter hooks the inner wall of the head to prevent the grinder from excessive displacement. Furthermore, the limiter is a bearing. After the head and the limiter are against each other, the bearing can rotate to prevent damage to the inner wall of the head. 5) The grinding machine can adjust the installation position according to the needs. The grinding machine can grind the upper edge or the outer peripheral side of the upper edge of the head. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present application is further described below in conjunction with the accompanying drawings.

[0019] The same or similar numbers in the drawings of the embodiments of the present application correspond to the same or similar parts; in the description of the present application, it should be understood that if the terms "top", "bottom", "left", "right", "front", "back", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0020] Please refer to Figure 1-Figure 6 An embodiment of the present application provides a chamfering and grinding tool, comprising a support frame 1 and a bottom plate 2, wherein the bottom plate 2 is rotatably arranged on the support frame 1, and at least one slide rail 3 is slidably arranged on the upper side of the bottom plate 2, wherein the slide rail 3 is connected to a bracket 4, and the bracket 4 is provided with a follower 405 that moves with the workpiece, and the follower 405 is rotatably connected to the bracket 4. When the workpiece is a head 10, a grinder 9 is detachably arranged on the chamfering and grinding tool, and the slide rail 3 can move along the bottom plate 2 Slide, when grinding, the staff holds the bracket 4 and pushes the grinder 9 to the edge of the head 10, the follower 405 is placed on the upper edge of the head 10, the rotating platform rotates, and the grinder 9 grinds the upper edge of the head 10. If the head 10 is non-circular, due to its diameter change, the head 10 will push the grinder 9 to drive the bracket 4 to retreat during the grinding process, ensuring that the grinder 9 is always at the outer peripheral side of the upper edge of the head 10. In this way, the edge grinding tooling can be applied to heads of various shapes.

[0021] When the head 10 is installed on the rotating platform, the opening of the head 10 faces upward, and it is difficult to keep the head 10 level. It takes a lot of time to level it. It is impossible to ensure that the grinder 9 remains in the appropriate position during grinding. The follower 405 is placed on the upper edge of the head 10. If the upper edge of the head 10 is uneven, the follower 405 will swing up and down during the rotation process. The follower 405 will drive the entire bracket 4 to swing up and down, and then drive the grinder 9 set on the bracket 4 to swing up and down, so that the grinder 9 can always fit the upper edge of the head 10 and be in a suitable grinding position, thereby improving production efficiency, reducing labor intensity, and improving the yield rate.

[0022] Specifically, the follower 405 is a roller shaft, and the outer peripheral surface of the roller shaft is smooth to prevent damage to the head 10.

[0023] like Figure 1-Figure 6 As shown, the support frame 1 is rotatably provided with a rotating shaft 6 near one end of the workpiece, and the base plate 2 is fixedly connected to the rotating shaft 6. Specifically, the number of the rotating shafts 6 is 2, and the two rotating shafts 6 are symmetrically arranged. The front part of the lower side of the base plate 2 is fixedly connected to the rotating shaft 6 to form a fulcrum. By utilizing the principle of lever, when the upper edge of the head 10 pushes the follower 405 to move upward, the follower 405 drives the bracket 4 to swing upward, and then drives the grinder 9 installed 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, and then when the upper edge of the head 10 returns to its original position, the bracket 4 and the grinder 9 will swing downward due to gravity, so that the follower 405 is always placed on the upper edge of the head 10 to ensure that the grinding position of the grinder 9 remains accurate.

[0024] Specifically, Figure 1-Figure 6As 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, a first support longitudinal rod 105 extending in the longitudinal direction 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 in the longitudinal direction is fixedly arranged between the first rear support vertical rod 103 and the second rear support vertical rod 104, and a first support cross bar extending in the transverse direction is fixedly arranged between the first front support vertical rod 101 and the second front support vertical rod 102. 107, a second support cross bar 108 extending in the transverse direction 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, the rotating shaft 6 is inserted in the rotating bearing 601, and the rotating shaft 6 can realize rotation, the support 109 is located above the bottom plate 2, the support 109 includes two symmetrically arranged inverted L-shaped side plates 1091, and the rotating bearing 601 is installed between the two side plates 1091.

[0025] like Figure 1-Figure 6 As shown, the bracket 4 includes a lower support plate 401, a hand-held rod 402 fixedly arranged on the upper side of the lower support plate 401, and an axle rod 403 vertically arranged on the hand-held rod 402. The follower 405 can be rotatably sleeved on the axle rod 403. The lower support plate 401 is fixedly connected to the slide rail 3. The hand-held rod 402 is convenient for the staff to hold the hand-held rod 402 and push the bracket 4 toward the outer peripheral side of the head 10. Furthermore, the hand-held rod 402 is made into a sleeve rod structure, that is, an adjusting sleeve 406 is sleeved on the hand-held rod 402, and the axle rod 403 is fixedly connected to the adjusting sleeve 406. A threaded hole is provided on the adjusting sleeve 406, and a bolt is screwed into the threaded hole, so that the follower 405 can adjust the height. During processing, the follower 405 is adjusted to any height and is mounted on the upper edge of the head 10, thereby adjusting the grinding angle to meet different groove angle requirements.

[0026] like Figure 1-Figure 6As shown, a limit frame 5 is provided at one end of the support frame 1 away from the workpiece. Specifically, the limit frame 5 includes a limit bottom rod 501 fixedly arranged on the support frame 1, a connecting vertical rod 502 fixedly arranged vertically on the limit bottom rod 501, and a limit upper rod 503 fixedly arranged vertically on the upper end of the connecting vertical rod 502. Specifically, the limit bottom rod 501 is fixedly connected to the second supporting cross bar 108. As the bottom plate 2 drives the slide rail 3 to swing up and down, the limit upper rod 503 abuts against the bottom plate 2 to prevent the bottom plate 2 from swinging excessively. A stop rod 8 is arranged across the two slide rails 3. When the slide rail 3 is in the original position, the stop rod 8 abuts against the limit upper rod 503 to form a limit. In particular, when the grinder 9 is installed, since the grinder 9 is heavy, the bottom plate 2 and the rear end of the slide rail are easily tilted upward during installation. The stop rod 8 abuts against the limit upper rod 503 to limit the upward tilting height of the rear end of the slide rail 3.

[0027] like Figure 1-Figure 6 As shown, a mounting rod 404 is vertically arranged at one end of the shaft rod 403 away from the hand-held rod 402, and the mounting rod 404 is rotatably sleeved with a limit portion 7. The staff may excessively move the grinder 9 during operation. When excessively moved, the limit portion 7 hooks the inner wall of the head 10 to prevent the grinder 9 from excessive displacement. Specifically, the limit portion 7 is a rolling bearing, so that after the head 10 is against the limit portion 7, the bearing can rotate to prevent damage to the inner wall of the head 10.

[0028] like Figure 1-Figure 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 rail 3 can be slidably inserted in the guide block 301. The slide rail 3 slides along the guide block 301, with good guiding effect and more stable movement.

[0029] See also Figure 1-Figure 6 The present application also provides an edge chopping and grinding device, including the edge chopping and grinding tooling and a grinder 9. The grinder 9 can be detachably arranged on the slide rail 3 or the lower support plate 401. A threaded hole is arranged on the slide rail 3, and a threaded hole is correspondingly arranged on the lower support plate 1. The grinder 9 is connected to the slide rail 3 and the lower support plate 401 through bolts, or a threaded hole is directly arranged on the lower support plate, and the grinder 9 is directly connected to the lower support plate 401 through bolts.

[0030] like Figure 1-Figure 6 As shown, the grinding disc 901 of the grinder 9 abuts against the outer peripheral side of the upper edge of the workpiece or against the upper edge of the workpiece. The grinder 9 adjusts the installation position as needed. The grinder 9 can grind the upper edge of the head 10 or the outer peripheral side of the upper edge.

[0031] The working process of an edge grinding device provided by a preferred embodiment of the present application is as follows: When grinding the outer peripheral side of the upper edge of the non-circular head 10, the head 10 is installed on the rotating platform with the opening of the head 10 facing upward. The staff holds the hand-held rod 402 to drive the grinder 9 to move toward the outer peripheral side of the upper edge of the head 10, and adjusts the height of the roller according to the different bevel angles to be ground. The rotating platform drives the head 10 to rotate, and the staff holds the hand-held rod 402 to drive the lower support plate 401 to move toward the outer peripheral side of the upper edge of the head 10. The slide rail 3 can slide along the guide block 301, thereby driving the grinder 9 to move toward the outer peripheral side of the upper edge of the head 10, and the roller rests on the upper edge of the head 10. When the upper edge of the head 10 is not horizontal, the roller swings up and down with the upper edge of the head 10 to ensure that the grinding is smooth. The grinder 9 always grinds the outer peripheral side of the upper edge of the head 10. Due to the large change in the diameter of the head 10, when the head 10 rotates from a small diameter to a large diameter, the grinder 9 will be pushed to move backward. At this time, the staff needs to push the grinder 9 forward with a little force to ensure that the grinder 9 is always in contact with the outer peripheral side of the upper edge of the head 10, and the roller is close to the upper edge of the head 10. The rotation of the head 10 brings the roller with it to prevent damage to the head 10. At the same time, when the angle requirements of the groove 1001 are different, the height of the roller is adjusted. In this way, the angle formed by the roller and the upper edge of the head 10 during grinding is different, thereby changing the grinding angle, thereby meeting different groove 1001 angle requirements.

[0032] Through on-site timing, it is found that it takes 10 minutes for a staff member to grind a non-circular head 10 with a handheld grinder 9. After using the edge chamfering and grinding device of the present application, it only takes 3 minutes to grind a head 10, saving 7 minutes for each head 10. A total of 1420 heads 10 were produced in 6 months, saving 1420*7 minutes=165 hours of working hours, saving production cycles, greatly reducing the labor intensity of the staff, improving production quality, and making the head 10 more compatible with the cylinder.

[0033] Any numerical value cited herein includes all values ​​of lower and upper values ​​that increase by one unit from the lower limit to the upper limit, and there is at least a two-unit interval between any lower value and any higher value. For example, if the value of the quantity of a component or a process variable (such as temperature, pressure, time, etc.) is set forth to be from 1 to 90, preferably from 20 to 80, and more preferably from 30 to 70, the purpose is to illustrate that values ​​such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also explicitly listed in the specification.
