Description

Technical Field

[0001] This utility model belongs to the technical field of lathe support devices, specifically relating to a support frame for a chisel turning equipment. Background Technology

[0002] Drill rods are indispensable components in mining equipment. During manufacturing, the threaded portion of the drill rod is friction-welded to one end, and stress at the weld site is released through a subsequent heat treatment process. Before friction welding, the end of the drill rod needs to be machined to ensure its flatness. In existing technology, during machining, the drill rod is placed on a support frame with grooves for holding it; then one end is clamped on a lathe for machining. However, the drill rod rotates around its axis under the action of the lathe's three-jaw chuck, resulting in radial displacement between the drill rod and the support frame, and generating significant noise.

[0014] In one possible implementation, the side of the carriage is rotatably provided with a support roller, the axis of which is perpendicular to the axis of the chisel, and the top of the support roller contacts the outer peripheral wall of the chisel.

[0015] Specifically, when the bottom rubber wheel is in its lowest position, the side rubber wheels open to both sides; the top height of the bottom rubber wheel is lower than the top height of the support roller; when the three sets of rubber wheels clamp the chisel, the top height of the bottom rubber wheel is higher than the top height of the support roller, so as to separate the chisel from the support roller.

[0016] In one possible implementation, an adjustment seat is slidably provided on one side of the carriage along the height direction, and the support roller is rotatably mounted on the adjustment seat;

[0017] The slide is rotatably provided with a screw, and the position of the screw relative to the slide is fixed; the adjusting seat has a threaded hole that rotatably engages with the screw.

[0018] In one possible implementation, the outer peripheral wall of the support roller has a concave surface, which is a rotating surface, to support and guide the chisel.

[0029] This utility model provides a support frame for a chisel turning machine. Compared with the prior art, the slide is slidably mounted on the slide rail, which can adjust the distance between the slide and the turning machine according to the length of the chisel. When the turning machine clamps the chisel, it ensures that the three sets of rubber wheels can hold the chisel and provide radial limiting for the chisel. During the rotation of the chisel, the rubber wheels can rotate with it, thereby reducing the radial vibration of the chisel and thus reducing noise. The drive mechanism drives the rubber wheels on both sides to swing outward, which increases the distance between the rubber wheels on both sides, making it easier to place the chisel between the three sets of rubber wheels. After the chisel is placed, the drive mechanism drives the rubber wheels on both sides to swing inward, so that all three sets of rubber wheels are tangent to the chisel, which can play a role in radial limiting for the chisel.

[0040] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0041] Please refer to the following: Figures 1 to 9 The present invention provides a support frame for a chisel turning machine. The support frame for the chisel turning machine is mounted on a slide rail 2. The slide rail 2 is positioned at the clamping end of the turning machine and extends outward along the axial direction of the clamping end. The support frame includes a slide 3 and a center frame 4. The slide 3 is slidably mounted on the slide rail 2, and the bottom of the slide 3 has a positioning component 5 detachably connected to the slide rail 2. The center frame 4 is positioned on top of the slide 3. The center frame 4 includes three sets of rubber wheels 41 evenly distributed circumferentially, each rubber wheel 41 rotatingly engaging with the slide 3. The bottom rubber wheel 41 is relatively fixed to the slide 3, while the rubber wheels 41 on both sides are hinged to the slide 3 via connecting rods 42. The rubber wheels 41 on both sides can swing outward to allow the chisel 1 to be placed on the bottom rubber wheel 41. The slide 3 has a drive mechanism 6 for driving the rubber wheels 41 on both sides to swing.

[0042] This utility model provides a support frame for a turning equipment for a chisel 1. Compared with the prior art, the slide 3 is slidably mounted on the slide rail 2, and the distance between the slide 3 and the turning equipment can be adjusted according to the length of the chisel 1. When the turning equipment clamps the chisel 1, it ensures that the three sets of rubber wheels 41 can clamp the chisel 1 and provide radial limiting for the chisel 1. During the rotation of the chisel 1, the rubber wheels 41 can rotate with it, thereby reducing the radial vibration of the chisel 1 and thus reducing noise. The drive mechanism 6 drives the rubber wheels 41 on both sides to swing outward, which increases the distance between the rubber wheels 41 on both sides, making it easier to place the chisel 1 between the three sets of rubber wheels 41. After the chisel 1 is placed, the drive mechanism 6 drives the rubber wheels 41 on both sides to swing inward, so that all three sets of rubber wheels 41 are tangent to the chisel 1, which can play a role in radial limiting for the chisel 1.

[0043] For example, the slide rail 2 is mounted on the base frame 21; there are two slide rails 2, both mounted on the top of the base frame 21, and the two slide rails 2 are spaced apart; the slide 3 has a sliding groove 31 that slides with the two slide rails 2. By setting two slide rails 2, the stability of the slide 3 during the sliding process can be improved. This embodiment uses two slide rails 2 as an example for explanation, but is not limited to two slide rails 2.

[0044] In some embodiments, such as Figures 1 to 9 As shown, the drive mechanism 6 includes two sets of gears 61, a sliding component 62, and a drive cylinder 63; the two sets of gears 61 correspond one-to-one with the connecting rods 42 and are connected to the hinge shafts of the corresponding connecting rods 42; the sliding component 62 is slidably mounted on the carriage 3 along the height direction; the sliding component 62 has a rack 64 that meshes with the gears 61; the drive cylinder 63 is connected to the carriage 3; the piston rod of the drive cylinder 63 is connected to the sliding component 62; the drive cylinder 63 can also be replaced by a hydraulic cylinder.

[0045] It should be noted that by driving the sliding component 62 through the drive cylinder 63, the rack 64 can slide, which in turn drives the gear 61 to rotate. During the rotation of the gear 61, the connecting rod 42 can swing, thereby causing the rubber wheels 41 on both sides to swing outward or inward. The gear 61 does not rotate a full circle; the gear 61 only needs to rotate a preset angle.

[0046] In addition, the swing of the two connecting rods 42 needs to be synchronized outward or inward, so the swing directions of the two connecting rods 42 are opposite.

[0047] In some embodiments, such as Figures 1 to 9As shown, the rubber wheel 41 at the bottom position is rotatably connected to the sliding component 62. When the sliding component 62 moves upward into position, the three sets of rubber wheels 41 clamp the drill rod 1. The side of the slide 3 is rotatably provided with a support roller 7. The axis of the support roller 7 is perpendicular to the axis of the drill rod 1, and the top of the support roller 7 contacts the outer peripheral wall of the drill rod 1. When the bottom rubber wheel 41 is in the lowest position, the side rubber wheels 41 open to both sides. The top height of the bottom rubber wheel 41 is lower than the top height of the support roller 7. When the three sets of rubber wheels 41 clamp the drill rod 1, the top height of the bottom rubber wheel 41 is higher than the top height of the support roller 7, so that the drill rod 1 is separated from the support roller 7.

[0048] It should be noted that when the chisel 1 is placed on the support frame, the rubber wheels 41 on both sides are in the open state. At this time, the height of the bottom rubber wheel 41 is lower than the height of the support roller 7. After the chisel 1 is placed on the support roller 7, the support roller 7 can support the chisel 1. After one end of the chisel 1 is slid to the clamping end of the turning equipment and clamped, it swings inward through the side rubber wheel 41. At this time, all three sets of rubber wheels 41 are in contact with the chisel 1, and the chisel 1 is separated from the support roller 7. When the chisel 1 rotates, friction between the chisel 1 and the support roller 7 can be avoided.

[0049] For example, the carriage 3 includes a base plate 32, a support plate 33, and two side plates 34; the bottom of the base plate 32 has a groove 31 that slides with the slide rail 2; the positioning component 5 is disposed on the base plate 32; the support plate 33 is connected to the top of the base plate 32; the top of the support plate 33 is connected to a support component 35, and the center frame 4 is disposed on the support component 35; the two side plates 34 are respectively located on both sides of the support component 35; each side plate 34 is connected to the base plate 32, the support plate 33, and the support component 35.

[0050] It should be noted that there are two carriages 3 on the slide rail 2, and each carriage 3 has a support roller 7. When the chisel 1 is placed on the two carriages 3, the support rollers 7 on the two carriages 3 can provide support. One of the two carriages 3 is equipped with a center frame 4, and the other carriage 3 is not equipped with a center frame 4. The carriage 3 without a center frame 4 is located between the turning equipment and the carriage 3 with a center frame 4. Therefore, when the center frame 4 clamps the chisel 1 and the clamping end of the turning equipment clamps the chisel 1, it can be ensured that the chisel 1 is placed horizontally and that the chisel 1 is separated from the support rollers 7 on the two carriages 3.

[0051] In some embodiments, such as Figures 1 to 9 As shown, an adjusting seat 71 is slidably provided on one side of the slide 3 along the height direction, and a support roller 7 is rotatably mounted on the adjusting seat 71; a screw 72 is rotatably provided on the slide 3, and the position of the screw 72 and the slide 3 is relatively fixed; the adjusting seat 71 has a threaded hole that rotatably engages with the screw 72.

[0052] It should be noted that the first position is when the top of the bottom rubber wheel 41 is at its lowest point, and the second position is when the top of the bottom rubber wheel 42 is at its highest point. After the adjusting seat 71 is installed on the slide 3, the height of the adjusting seat 71 can be adjusted by rotating the screw 72 so that the height of the top of the support roller 7 is between the first and second positions. When the chisel 1 is placed, the chisel 1 is in contact with the support roller 7, and the support roller 7 supports the chisel 1. At this time, the chisel 1 is separated from the bottom rubber wheel 41. When the three sets of rubber wheels 41 clamp the chisel 1, the height of the chisel 1 will be raised, so that the chisel 1 is separated from the support roller 7.

[0053] In some embodiments, such as Figures 1 to 9 As shown, the outer peripheral wall of the support roller 7 has a concave surface 73, which is a rotating surface, to support and guide the drill rod 1.

[0054] It should be noted that the concave surface 73 is composed of two conical surfaces, which are symmetrically arranged about the middle position of the support roller 7, and the middle position of the support roller 7 is the position with the smallest diameter of the conical cross-section. With the above arrangement, when the support roller 7 supports the chisel 1, the chisel 1 can be stably positioned in the middle position of the support roller 7, which plays a positioning role and makes it easier for the rubber wheel 41 to clamp the chisel 1.

[0055] In some embodiments, such as Figures 1 to 9 As shown, the slide rail 2 is provided with a plurality of positioning holes 22 at intervals along its length. The positioning component 5 includes a positioning frame 51, a positioning rod 52, and an elastic element 53. The positioning frame 51 is connected to the slide 3. The positioning frame 51 has a through hole that slides and engages with one of the positioning holes 22. The positioning rod 52 is disposed in the through hole of the positioning frame 51 and slides and engages with the positioning frame 51. The two ends of the elastic element 53 are connected to the positioning rod 52 and the positioning frame 51, respectively. Under the action of the elastic force of the elastic element 53, the positioning rod 52 can maintain the state of being inserted and engaged with the positioning hole 22. The positioning frame 51 is fixed on the base plate 32.

[0056] For example, the elastic element 53 is a spring, which is sleeved on the positioning rod 52, and the two ends of the spring are respectively connected to the positioning rod 52 and the positioning frame 51; by the spring providing elastic force to the positioning rod 52, the positioning rod 52 can be kept in the state of being inserted into the positioning hole 22.

[0057] In some embodiments, such as Figures 1 to 9 As shown, the slide rail 2 has several scales along its length, and the carriage 3 has a pointer 36 pointing to one of the scales.

[0058] It should be noted that the scale is set on the base frame 21 and the pointer 36 is fixed on the base plate 32. During the sliding of the carriage 3, the pointer 36 can point to one of the scales, which makes it easy for the operator to know the distance between the carriage 3 and the turning equipment, and thus makes it easy to adjust the position of the carriage 3 according to the length of the chisel 1.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
