The locking assembly locks the position of the first positioning plate, exposing more of the unprocessed and non-sharp parts of the high-speed steel drill bit semi-finished product to the outside of the device. Therefore, when removing the high-speed steel drill bit semi-finished product, the unprocessed and non-sharp parts can be pinched and removed, thus solving the problem of inconvenience in removing high-speed steel semi-finished products from transfer clamps, which easily causes hand cuts or glove tears.

Description

Technical Field

[0001] This utility model belongs to the field of drill bit transfer and conveying, and specifically relates to a high-speed steel drill bit semi-finished product transfer and conveying device. Background Technology

[0002] High-speed steel drill bit semi-finished products refer to drill bit intermediate products that have completed the main material and shape processing, but have not yet undergone key processes such as final heat treatment, cutting edge fine grinding, and surface coating. They are in the intermediate manufacturing stage from raw materials to finished drill bits. In the main raw material and shape processing of high-speed steel drill bits, rolling, forging, and extrusion methods are mostly used. This results in the semi-finished high-speed steel drill bits typically having a high temperature. Before entering the next processing stage, the semi-finished high-speed steel drill bits usually need to be cooled down and transferred to the next processing location. In most existing high-speed steel drill bit semi-finished products, the process of transportation involves placing them in a specific jig. Once cooled, the semi-finished product is removed for further processing. However, to improve the cooling efficiency during transportation, the semi-finished product is usually inserted into the jig. To prevent wear on the machined parts and facilitate removal, the machined portion of the drill bit is typically extended out of the jig, while the remaining parts are placed inside. However, since the machined parts of the high-speed steel drill bit semi-finished products are usually quite sharp, directly holding them can easily cut hands or tears gloves, making it inconvenient to remove the semi-finished product.

[0015] This embodiment discloses a high-speed steel drill bit semi-finished product 150 transfer and conveying device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it may include: A positioning component 100 includes a first positioning module 110, a second positioning module 120, a third positioning module 130, and an elastic module 140. The first positioning module 110 includes a first positioning plate 111 and a plurality of first positioning holes 112. The first positioning holes 112 penetrate both ends of the first positioning plate 111 in the vertical direction along its thickness. The second positioning module 120 includes a second positioning plate 121 and a plurality of second positioning holes 122. The second positioning holes 122 penetrate both ends of the second positioning plate 121 in the vertical direction along its thickness. The central axis of the first positioning plate 12 and the central axis of the second positioning hole 122 are vertically aligned and identical; the first positioning plate 111, the second positioning plate 121, and the third positioning module 130 are spaced apart vertically; the second positioning plate 121 is located between the first positioning plate 111 and the third positioning module 130; the first positioning plate 111 and the third positioning module 130 are slidably connected; the second positioning plate 121 is connected to the third positioning module 130; the elastic module 140 is slidably connected to the third positioning module 130; the first positioning plate 111 and the second positioning plate 121 respectively abut against the elastic module 140; Locking assembly 200; the locking assembly 200 is located between the first positioning plate 111 and the second positioning plate 121; the first positioning plate 111 and the second positioning plate 121 are respectively connected to the locking assembly 200.

[0016] In this embodiment, a first positioning plate 111 and a second positioning plate 121 are provided, with a first positioning hole 112 on the first positioning plate 111 and a second positioning hole 122 on the second positioning plate 121. The first positioning plate 111 is slidably connected to the third positioning module 130; the second positioning plate 121 is connected to the third positioning module 130; the elastic module 140 is slidably connected to the third positioning module 130; the first positioning plate 111 and the second positioning plate 121 respectively abut against the elastic module 140, and further provided... The locking assembly 200 is installed; the high-speed steel drill bit semi-finished product 150 is placed between the first positioning plate 111 and the second positioning plate 121 through the first positioning hole 112 and the second positioning hole 122, and the third positioning module 130 abuts against the high-speed steel drill bit semi-finished product 150 in the vertical direction; when the high-speed steel drill bit semi-finished product 150 has cooled down and needs to be removed, the first positioning plate 111 is pressed down, the first positioning plate 111 compresses the spring downward until the first positioning plate 111 reaches the predetermined position, and the locking assembly 200 will then lock the high-speed steel drill bit semi-finished product 150. The positioning plate 111 locks the position, exposing more of the unprocessed, non-sharp parts of the high-speed steel drill bit semi-finished product 150 to the outside of the device. This allows the unprocessed, non-sharp parts of the high-speed steel drill bit semi-finished product 150 to be pinched and removed when taken out, thus solving the problem of inconvenience in removing high-speed steel semi-finished products from transport fixtures, which can easily cause hand cuts or glove tears. In this embodiment, it is conceivable that, to facilitate the transportation of the high-speed steel drill bit semi-finished product 150, the exposure of the high-speed steel drill bit semi-finished product 150 should be minimized as much as possible, thereby preventing the processed parts of the high-speed steel drill bit semi-finished product 150 from contacting hard objects, causing damage to the processed parts of the high-speed steel drill bit, or causing the drill bit to cut workers. In this embodiment, the elastic module 140 is a spring or other existing known elastic device applicable to the scenario of this utility model. In this embodiment, the locking assembly 200 is a push-button latch switch (model PR-001 / 002 door lock switch).

[0017] In some embodiments of this utility model, such as Figure 1 , Figure 5 As shown, the latch assembly 200 includes a lock body module 210 and a male connector module 220; the lock body module 210 is connected to the second positioning plate 121; the male connector module 220 is connected to the first positioning plate 111; the lock body module 210 and the male connector module 220 are movably connected; in some other embodiments (not shown in the figure), the latch assembly 200 includes a lock body module 210 and a male connector module 220; the lock body module 210 is connected to the first positioning plate 111; the male connector module 220 is connected to the second positioning plate 121; the lock body module 210 and the male connector module 220 are movably connected.

[0018] In this embodiment, pressing down on the first positioning plate 111 finally achieves the engagement between the lock body module 210 and the male connector module 220; pressing down on the first positioning plate 111 again separates the lock body module 210 from the male connector module 220, and the first positioning plate 111 is reset under the elastic force of the elastic module 140; in this embodiment, since the latch assembly 200 is an application of existing conventional technology, the specific structure of the lock body module 210 and the male connector module 220 is not described in detail in this embodiment; the connection method between the lock body module 210 and the first positioning plate 111 or the second positioning plate 121, or the connection method between the male connector module 220 and the first positioning plate 111 or the second positioning plate 121, is described in detail in this embodiment. The connection method of the second positioning plate 121 or the first positioning plate 111 can be screws or other detachable connection methods. In this embodiment, it can be imagined that in order to facilitate the connection between the lock body module 210, the male connector module 220 and the first positioning plate 111 or the second positioning plate 121, corresponding protrusions can be added to the relevant parts of the lock body module 210 and the male connector module 220 to facilitate the setting of holes, which are convenient for screws or wires to pass through. Similarly, holes or screw holes are also provided on the first positioning plate 111 and the second positioning plate 121 for screw connection or wire passage. In this embodiment, the number and position of the latch assembly 200 can be set according to actual needs.

[0019] In some embodiments of this utility model, such as Figure 1 , Figure 2As shown; the third positioning module 130 includes a third positioning plate 131 and a plurality of screw tubes 132; one end of each screw tube 132 along its axial direction is fixedly connected to one end face of the third positioning plate 131 in the vertical direction, and the other end is spaced apart from the third positioning plate 131 in the vertical direction; the end of the screw tube 132 away from the third positioning plate 131 is threadedly connected to a screw; the first positioning module 110 also includes a plurality of first connecting holes 113; the first connecting holes 113 penetrate both end faces of the first positioning plate 111 along the thickness direction; the axis of the first connecting hole 113 is parallel to the axis of the first positioning hole 112 in the vertical direction, and the first positioning hole 112 and the first connecting hole 113 are spaced apart; the first positioning hole 112 is located in the area enclosed by the first connecting holes 113; the second positioning module 120 also includes Multiple second connecting holes 123; the second connecting holes 123 penetrate both ends of the second positioning plate 121 along the thickness direction of the second positioning plate 121; the axis of the second connecting hole 123 is parallel to the axis of the second positioning hole 122 in the vertical direction, and the second positioning hole 122 and the second connecting hole 123 are spaced apart; the second positioning hole 122 is located in the area enclosed by the second connecting holes 123; the central axis of the first connecting hole 113 corresponds one-to-one with the axis of the second connecting hole 123 in the vertical direction and is the same; the central axis of the screw tube 132 corresponds one-to-one with the central axis of the first connecting hole 113 in the vertical direction and is the same; the inner peripheral surface of the first connecting hole 113 is slidably connected to the outer peripheral surface of the screw tube 132; the first positioning plate 111 abuts against the screw; the inner peripheral surface of the second connecting hole 123 is connected to the outer peripheral surface of the screw tube 132.

[0020] In this embodiment, the second positioning plate 121 and the third positioning plate 131 are spaced apart. In some cases, the second positioning plate 121 can be fixedly connected to the screw tube 132 (e.g., by welding or snap-fit); so that the high-speed steel drill bit semi-finished product 150 can be better fixed; such as Figure 1 , Figure 2 As shown, the screw abuts against the first positioning plate 111, thereby limiting the sliding range of the first positioning plate 111, so that the first positioning plate 111 can only slide on the screw tube 132; in some other embodiments, the screw can also be replaced by a locking block to prevent the first positioning plate 111 from sliding upward and disengaging from the screw tube 132 under the elastic force of the elastic module 140.

[0021] In some embodiments of this utility model, such as Figure 1 , Figure 2As shown, the third positioning module 130 further includes a plurality of partition blocks 133; the partition blocks 133 are fixedly connected to the outer peripheral surfaces of the screw tube 132 one by one; the end of the partition block 133 away from the third positioning plate 131 in the vertical direction is located in the same horizontal plane; the end of the partition block 133 away from the third positioning plate 131 abuts against the second positioning plate 121; the second positioning plate 121 is slidably connected to the screw tube 132.

[0022] In this embodiment, by setting multiple partition blocks 133, the second positioning plate 121 can abut against the partition blocks 133, and the second positioning plate 121 is slidably connected to the screw tube 132, thereby facilitating the removal of the second positioning plate 121 from the screw tube 132 or facilitating the placement of the second positioning plate 121 on the bolt tube, thus realizing the rapid assembly of the second positioning plate 121.

[0023] In some embodiments of this utility model, as shown in Figure 4; the second positioning module 120 further includes multiple spring pieces 124; the spring pieces 124 are located between the second positioning plate 121 and the third positioning plate 131; one end of the spring piece 124 in the vertical direction is fixedly connected to the second positioning plate 121, and the other end is spaced apart from the third positioning plate 131; the spring pieces 124 are spaced apart around the second positioning hole 122; the area formed by the spring pieces 124 surrounding the second positioning hole 122 gradually decreases from the end close to the second positioning plate 121 to the end away from the second positioning plate 121; the area formed by the spring pieces 124 surrounding the second positioning hole 122 away from the end of the second positioning hole 122 is located within the projection of the second positioning hole 122 along its axial direction.

[0024] In this embodiment, by setting the spring piece 124, the high-speed steel drill bit semi-finished product 150 can be pressed by the spring piece 124 after being inserted into the second positioning hole 122, preventing the high-speed steel drill bit semi-finished product 150 from slipping out of the device during transportation; thus ensuring the safety of transportation; in this embodiment, the pressure of the spring piece 124 on the high-speed steel drill bit semi-finished product 150 can be set according to actual needs, specifically by changing the size of the area formed by the circumferential spring piece 124 surrounding the second positioning hole 122; while satisfying a certain degree of positioning of the high-speed steel drill bit semi-finished product 150, it is also possible to remove the high-speed steel drill bit semi-finished product 150 without expending too much force.

[0025] In some embodiments of this utility model, such as Figure 1As shown, the third positioning module 130 also includes a plurality of support pads 135; the connecting part of the support pad 135 is detachably fixedly connected to the end of the third positioning plate 131 away from the second positioning plate 121 in the vertical direction; the support pad 135 is located outside the area enclosed by the screw tube 132.

[0026] In this embodiment, by setting multiple support pads 135, a certain gap can be made between the third positioning plate 131 and the ground, which makes it easier for workers to move the device. In this embodiment, it can be imagined that the third positioning plate 131 is provided with a corresponding number of holes for the support pads 135 to place the support pads 135.

[0027] The working principle of this utility model is as follows: The high-speed steel drill bit semi-finished product 150 is inserted into the first positioning hole 112 and the second positioning hole 122, and transported to the predetermined location along with the high-speed steel drill bit semi-finished product 150 transfer and conveying device. When it is necessary to remove the high-speed steel drill bit semi-finished product 150, the first positioning plate 111 is pressed, so that the locking body module 210 in the locking assembly 200 is engaged with the male end module 220; the unprocessed and non-sharp part of the high-speed steel drill bit semi-finished product 150 is exposed as much as possible, and then the unprocessed and non-sharp part of the high-speed steel drill bit semi-finished product 150 is pinched and pulled out until all the high-speed steel drill bit semi-finished products 150 are pulled out; the first positioning plate 111 is pressed, so that the locking body module 210 is disengaged from the male end module 220, and the first positioning plate 111 is reset under the elastic force of the elastic module 140.

[0028] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the spirit and scope of this disclosure.
