Description

Technical Field

[0001] This utility model relates to the field of tooling equipment technology, and in particular to a tooling fixture for punching and positioning angle steel. Background Technology

[0002] Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other at a 90° angle. It is widely used in the machinery industry to provide connections and reinforcement for various mechanical mechanisms. Currently, in the processing of angle steel, to meet other usage requirements and reduce its weight, it is often punched. During the punching process, workers need to manually place the angle steel into a positioning fixture before starting the punching operation. However, the positioning fixtures currently used are usually only suitable for one or a limited number of different sizes of angle steel, resulting in low versatility. Furthermore, the angle steel must be manually removed from the fixture each time before continuing the operation, which is inefficient. Moreover, operational errors can easily lead to worker injuries, compromising worker safety. Utility Model Content

[0017] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figures 1-2 As shown, this example provides a positioning fixture for punching angle steel, including: a base 100 and a positioning component 200.

[0019] A rotating frame 101 that rotates around its own axis is installed at the center of the base 100; the positioning assembly 200 includes a plurality of support seats 201 mounted on the rotating frame 101 and evenly spaced along the circumference of the base 100 and movable radially along the base 100. Each support seat 201 has two support plates 202 located at its two ends and moving towards each other. The support seats 201 have upright plates 203 located between the support plates 202 on both sides for supporting the angle steel, and the side of the upright plate 203 away from the center of the base 100 abuts against the inner side of the angle steel; a punching block that moves vertically above one of the support seats 201 is used to punch holes in the angle steel.

[0020] Specifically, the support plate 202 has vertically arranged elongated holes 204 on its side. A movable ring 205 is slidably fitted in the elongated hole 204. The movable ring 205 is respectively sleeved on the two opposite threads of the double-acting screw 206. The double-acting screw 206 is installed on the support base 201. By rotating the double-acting screw 206, the movable rings 205 can move synchronously in opposite directions, which in turn drives the support plate 202 to move synchronously, thereby adjusting the position of the support plate 202 to accommodate angle steel of different sizes. In addition, the presence of the elongated hole 204 can also prevent the double-acting screw 206 from being damaged by impact during the punching process.

[0021] Specifically, each of the upright plates 203 has two through-grooves 207 on its top surface. A crossbar 208 is provided between the support plates 202. The crossbar 208 is inverted L-shape, with its horizontal section fitting into the groove 207 and its top flush with the top surface of the support plate 202. The crossbar 208 provides support for the middle of the angle steel. A positioning pin 209 passes through the vertical section of the crossbar 208 and is mounted on the movable plate 210. The movable plate 210 is fitted onto the guide rod 211, with both ends of the guide rod 211 mounted on protrusions 212. The protrusions 212 are mounted near the center of the base 100. On the upright plate 203, a first spring 213 is sleeved on the guide rod 211. The two ends of the first spring 213 abut against the protrusion 212 and the moving plate 210 respectively, and are always in a compressed state, thereby positioning the crossbar 208 and preventing it from falling. When two holes need to be punched along the length of the angle steel, the crossbar 208 supports the middle of the angle steel. When only one hole needs to be punched on the angle steel, the crossbar 208 can be removed. The angle steel that only needs one hole is usually small in size, and the support of the support plate 202 and the upright plate 203 is sufficient to meet the load-bearing requirements of the angle steel.

[0022] Specifically, a limiting part 214 is provided on the outer side of the support plate 202. The limiting part 214 is in the shape of an inverted L and is used to limit the two ends of the angle steel.

[0023] Specifically, the support plate 202 has a side plate 215 at one end away from the center of the base 100. The side plate 215 is L-shaped, and a horizontally arranged top rod 216 passes through its short end. A limiting block 217 is provided at one end of the top rod 216 facing the center of the base 100. The top of the limiting block 217 has an inclined surface facing the center of the base 100. A second spring 218 is sleeved on the top rod 216. The two ends of the second spring 218 abut against the side plate 215 and the limiting block 217 respectively, and are always in a compressed state. The other end of the top rod 216 has a retaining ring 219 for abutting against the side plate 215. When the angle steel is placed on the support plate 202, the lower end of the angle steel will contact the inclined surface of the limiting block 217, and force the limiting block 217 to move. The second spring 218 is also further compressed until the bottom surface of the horizontal section of the angle steel contacts the support plate 202. At this time, the end of the limiting block 217 contacts the side of the angle steel, thereby limiting the angle steel.

[0024] Specifically, the top of the rotating frame 101 is provided with a plurality of evenly spaced concave portions 102 along the circumferential direction. The support seat 201 is slidably fitted in the concave portions 102 and is moved along its width direction so as to adjust the distance between the support seat 201 and the center of the base 100 according to the position of the angle steel punching hole, so that the punching block can punch holes at the corresponding position of the angle steel. For example, the support seat 201 can be fitted on a screw and locked with a nut. The rotating frame 101 is mounted on the rotating shaft 103, which is rotatably mounted on the base 100. The rotation of the rotating shaft 103 can be done manually or by using a motor to drive it.

[0025] Specifically, the base 100 is provided with a through hole 104 that runs vertically through the base. During the punching operation, one of the concave portions 102 is aligned with the through hole, and the base 100 is also provided with a through hole in the middle to facilitate the falling of the excess material from the angle steel punching.

[0026] Specifically, a locking block 104 is provided on the base 100 and is arranged to move vertically. The locking block 104 is L-shaped. When punching, the locking block 104 engages with the right angle of the concave part 102 to prevent the rotating frame 101 from rotating and to ensure the smooth progress of the punching operation.

[0027] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
