Description

Technical Field

[0001] This utility model relates to the field of workpiece chip removal tooling technology, specifically a chip removal tooling for irregularly shaped workpieces. Background Technology

[0002] Reference Figure 4 As shown, the irregular workpiece 4 is shaped like a trapezoid, with protruding bottom ends on both sides and assembly holes 401. When the irregular workpiece 4 is in the blank stage, its two assembly holes 401 are blocked by aluminum chips, and subsequent processes need to remove the aluminum chips blocking the assembly holes 401.

[0003] Currently, workers typically remove aluminum chips 401 by hand-holding the irregularly shaped workpiece 4 and using a short shaft to pass through the assembly hole 401. However, due to the large number of irregularly shaped workpieces 4 in the raw stage, workers often neglect to punch some of them during processing, resulting in defective workpieces 4 leaving the factory and significantly reducing their production quality. Furthermore, manual punching is labor-intensive, further increasing the production cost of the irregularly shaped workpieces 4.

[0004] Therefore, a tooling for removing aluminum chips suitable for irregularly shaped workpieces is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling for removing aluminum chips from irregularly shaped workpieces, so as to solve the problem that the existing solutions mentioned in the background art, when removing aluminum chips from the assembly holes of irregularly shaped workpieces, rely on manual operation, which leads to a significant increase in labor intensity and a decrease in production quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tooling for removing aluminum chips from irregularly shaped workpieces, including a base plate, with positioning and ejection components provided on both the left and right sides of the top surface of the base plate, and a rotary cylinder provided at the center of the top surface of the base plate, with a top pressure plate fixedly connected to the upward-facing movable end of the rotary cylinder. The positioning ejection assembly includes a convex block. The top surface of the convex block has a horizontal groove parallel to the length direction of the convex block. The inner top surface of the horizontal groove is provided with positioning pins at both the left and right ends of the convex block. The top of the positioning pin is set as a sharp point. The rotary cylinder controls the extension, retraction, or rotation of the top pressure plate, which is used to press down the irregularly shaped workpiece located in the horizontal groove.

[0007] Preferably, the irregularly shaped workpiece is trapezoidal in shape, with protruding bottom ends on both sides and assembly holes.

[0008] Preferably, the width of the transverse groove is not less than the width of the irregularly shaped workpiece.

[0009] Preferably, the straight-line distance between the two locating pins is equal to the distance between the two mounting holes.

[0010] Preferably, the diameter of the locating pin is not greater than the inner diameter of the assembly hole.

[0011] Preferably, the tip of the locating pin is a cone.

[0012] Preferably, the width of the transverse groove is equal to the width of the irregularly shaped workpiece.

[0013] Preferably, the diameter of the locating pin is equal to the inner diameter of the assembly hole.

[0014] Preferably, the height of the irregularly shaped workpiece is not less than the depth of the transverse groove.

[0015] Preferably, the movable end of the rotary cylinder is fixedly connected to the center of the bottom surface of the top pressure plate, and the length of the top pressure plate is greater than the distance between the two irregularly shaped workpieces located in the transverse groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This tooling, through the setting and cooperation of the base plate, rotary cylinder and positioning ejection assembly, utilizes the rotary cylinder to control the extension or rotation of the top pressure plate to press down the irregular workpiece placed in the horizontal groove, thereby quickly and simultaneously completing the aluminum chip removal operation of two irregular workpieces. It has a high degree of automation, improves the efficiency of aluminum chip removal, and greatly reduces labor intensity and corresponding production costs. At the same time, since the irregular workpiece that has not undergone aluminum chip removal does not fall completely into the horizontal groove, the operator can quickly detect whether the irregular workpiece has completed aluminum chip removal, reducing the operation of forgetting to remove aluminum chips due to negligence, and greatly improving the production quality of irregular workpieces.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1-4 As shown, this utility model provides a technical solution for a chip removal fixture for irregularly shaped workpieces: A tooling for irregularly shaped workpieces includes a base plate 1. Positioning and ejection components 3 are provided on both the left and right sides of the top surface of the base plate 1. A rotary cylinder 2 is provided at the center of the top surface of the base plate 1. The movable end of the rotary cylinder 2 is provided facing upward and fixedly connected to a top pressure plate 201.

[0021] The positioning ejection assembly 3 includes a convex block 301. The top surface of the convex block 301 is provided with a horizontal groove 302 parallel to the length direction of the convex block 301. The inner top surface of the horizontal groove 302 is provided with positioning pins 303 at both the left and right ends of the convex block 301. The top end of the positioning pin 303 is set as a pointed tip.

[0022] The rotary cylinder 2 controls the extension, retraction, or rotation of the top pressure plate 201 to press down the irregular workpiece 4 located in the horizontal groove 302.

[0023] The working principle of this tooling is explained through its usage process: The operator first fixes the base plate 1 to the workbench by welding or screwing, keeping the base plate 1 horizontal. The irregular workpiece 4 is then placed in the horizontal groove 302. It should be noted that since the irregular workpiece 4 includes the assembly hole 401, the assembly hole 401 needs to be aligned with the positioning pin 303. Because there are aluminum shavings in the assembly hole 401, at this time, the tip of the positioning pin 303 is located in the assembly hole 401 but does not protrude from the assembly hole 401, and the irregular workpiece 4 has not completely fallen into the horizontal groove 302. After the irregular workpiece 4 is placed, the rotary cylinder 2 is started. The rotary cylinder 2 controls the top pressure plate 201 to rise and rotate above the two irregular workpieces 4. At this time, the rotary cylinder 2 controls the top pressure plate 201 to fall, thereby pressing down the two irregular workpieces 4 at the same time. At this time, the positioning pin 303 will pierce the aluminum shavings, completing the removal of aluminum shavings from the irregular workpiece 4.

[0024] Since the irregularly shaped workpiece 4, which has not undergone aluminum shavings removal, cannot fall completely into the horizontal groove 302, the workers can place the irregularly shaped workpiece 4, which is unsure whether aluminum shavings have been removed, into the horizontal groove 302 to determine whether the aluminum shavings removal operation has been completed. This reduces the chance of forgetting to remove aluminum shavings during the punching operation due to negligence, and greatly improves the production quality of the irregularly shaped workpiece 4.

[0025] The convex block 301 is convex in shape, which makes the middle of the side wall of the horizontal groove 302 higher, making it easier to put the irregular workpiece 4 in. The two sides of the side wall of the horizontal groove 302 are lower, making it easier for the operator to align the assembly hole 401 with the positioning pin 303. This design greatly improves the operating efficiency of this tooling.

[0026] This fixture, through the setup and collaboration of a base plate 1, a rotary cylinder 2, and a positioning and ejection assembly 3, utilizes the rotary cylinder 2 to control the extension, retraction, or rotation of the top pressure plate 201 to press down the irregularly shaped workpiece 4 placed in the transverse groove 302. This allows for quick and simultaneous removal of aluminum chips from two irregularly shaped workpieces 4, resulting in a high degree of automation, improved efficiency in aluminum chip removal, and significant reduction in labor intensity and corresponding production costs. Furthermore, since the irregularly shaped workpiece 4 that has not undergone aluminum chip removal does not completely fall into the transverse groove 302, operators can quickly check whether the aluminum chip removal of the irregularly shaped workpiece 4 has been completed, reducing the risk of forgetting to remove aluminum chips due to negligence and greatly improving the production quality of the irregularly shaped workpiece 4.

[0027] Reference Figure 1-4 As shown, in an optional embodiment: the irregular workpiece 4 is trapezoidal in shape, with protruding bottom ends on both sides and provided with assembly holes 401. It should be noted that the assembly holes 401 penetrate through the protruding parts at the bottom ends on both sides of the irregular workpiece 4.

[0028] Reference Figure 1-4 As shown, in an optional embodiment, the width of the horizontal groove 302 is not less than the width of the irregularly shaped workpiece 4. It should be noted that this arrangement allows the irregularly shaped workpiece 4 to be placed within the horizontal groove 302.

[0029] Reference Figure 1-4 As shown, in an optional embodiment, the linear distance between the two locating pins 303 is equal to the distance between the two mounting holes 401. It should be noted that this arrangement ensures that the two locating pins 303 are matched with the two mounting holes 401.

[0030] Reference Figure 1-4 As shown, in an optional embodiment, the diameter of the locating pin 303 is not greater than the inner diameter of the mounting hole 401. It should be noted that this arrangement allows the locating pin 303 to penetrate the mounting hole 401.

[0031] Reference Figure 1-4 As shown, in an optional embodiment, the tip of the positioning pin 303 is a cone. It should be noted that with this configuration, because the side of the cone is smooth, when the side of the tip of the positioning pin 303 collides with the inner wall of the bottom of the mounting hole 401 during the alignment of the positioning pin 303 with the mounting hole 401, it is less likely to scratch the inner wall of the mounting hole 401, thus improving operational safety.

[0032] Reference Figure 1-4 As shown, in an optional embodiment, the width of the horizontal groove 302 is equal to the width of the irregularly shaped workpiece 4. It should be noted that this arrangement allows the irregularly shaped workpiece 4 to be stably placed within the horizontal groove 302, preventing it from shaking or shifting during the pressing process, thereby improving the accuracy of the aluminum chip removal operation.

[0033] Reference Figure 1-4 As shown, in an optional embodiment, the diameter of the locating pin 303 is equal to the inner diameter of the assembly hole 401. It should be noted that this arrangement allows the locating pin 303 to move upwards against the inner wall of the assembly hole 401, thereby cleaning the aluminum shavings inside the assembly hole 401 more thoroughly and improving the working quality of this tooling.

[0034] Reference Figure 1-4 As shown, in an optional embodiment, the height of the irregularly shaped workpiece 4 is not less than the depth of the transverse groove 302. It should be noted that this arrangement allows the irregularly shaped workpiece 4 to conform to the inner top surface of the transverse groove 302 under the downward pressure of the top plate 201. At this time, the positioning pin 303 completely passes through the assembly hole 401, pushing the aluminum chips out of the assembly hole 401, thereby improving the efficiency of removing aluminum chips from the assembly hole 401.

[0035] Reference Figure 1-4 As shown, in an optional embodiment: the movable end of the rotary cylinder 2 is fixedly connected to the center of the bottom surface of the top pressure plate 201, and the length of the top pressure plate 201 is greater than the distance between the two irregularly shaped workpieces 4 located in the transverse groove 302. It should be noted that, with this arrangement, it can be ensured that the top pressure plate 201 can act on the two irregularly shaped workpieces 4 simultaneously during the pressing process, thereby improving work efficiency.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
