Description

Technical Field

[0001] This utility model relates to tooling for engineering machinery, and in particular to a slot center positioning device. Background Technology

[0002] When positioning a workpiece, it is often required that the machined hole be positioned with the center of the workpiece groove. However, the center line is a virtual line and cannot be directly used for positioning. If a two-sided positioning method is used, the workpiece will be jammed. Generally, it is converted to single-sided positioning of the groove. However, if the workpiece itself is long, even a slight deviation between the two sides of the groove will result in a large deviation between the simulated center line and the original center line. Moreover, the dimensions of each machined product will vary due to different references, failing to meet the dimensional requirements of the drawing. If this simple machining process requires aligning the groove center on the machining center every time before machining, it will inevitably lead to a waste of machine tool resources and extremely low machining efficiency.

[0003] In summary, how to achieve center positioning of the slot on the workpiece to facilitate subsequent processing has become an urgent problem for researchers in this field. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to achieve center positioning of the groove on the workpiece to facilitate subsequent processing of the workpiece; To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model is a slot center positioning device, comprising: a drill template placed on the upper surface of a workpiece, wherein at least two positioning components are provided on the drill template; The positioning assembly includes: a positioning plate fixedly connected to the drilling template, wherein a horizontally penetrating mounting hole is provided in the positioning plate, and two positioning shafts are symmetrically placed in the mounting hole; a mounting sleeve is installed at the center of the positioning plate, and a driving rod is vertically provided in the mounting sleeve, wherein the bottom of the driving rod abuts against the abutting ends of the two positioning shafts, and the driving rod moves downward to drive the two positioning shafts to move synchronously in opposite directions, and aligns the working ends of the two positioning shafts with the opposite sidewalls of the groove of the workpiece.

[0005] Furthermore, the mounting sleeve has an internal thread, and the outer wall of the drive rod is provided with an external thread that matches the internal thread. When the drive rod is rotated, the drive rod moves up and down relative to the mounting sleeve.

[0006] Furthermore, both the bottom end of the drive rod and the abutment end of the positioning shaft have a frustum portion.

[0007] Furthermore, a cover plate is provided on the positioning plate opposite to the side wall, and the actuating end of the drive rod passes through the cover plate.

[0008] Furthermore, a stepped surface is provided on the positioning shaft, and an elastic element is sleeved on the positioning shaft. One end of the elastic element abuts against the stepped surface, and the other end abuts against the cover plate.

[0009] Furthermore, a lever is vertically connected to the top of the drive rod, and rotating the lever drives the drive rod to rotate.

[0010] The beneficial effects of this utility model are as follows: This utility model is a slot center positioning device. The device is positioned at the center of the slot, and the positioning shaft is positioned and tightened with the opposite sides of the slot. The processing datum is consistent with the datum required by the drawing, thus ensuring the quality of the product. Secondly, this device only requires placing the positioning plate into the slot and rotating the drive rod to automatically align the positioning shaft to the center. Rotating the drive rod in the opposite direction will easily remove the device, making it convenient for positioning and removal. Finally, this device only needs to be placed on the workpiece and clamped with the positioning shaft before it can be processed on a regular drilling machine, which greatly improves work efficiency. Compared with this device, the time cost of machining center is much higher, which greatly saves workpiece processing costs. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] See Figure 1-3This embodiment is a slot center positioning device. A drill template 02 is placed on the upper surface of the workpiece 01. At least two positioning components 1 are provided on the drill template 02. The positioning component 1 includes: a positioning plate 2 fixedly connected to the drill template 02. The positioning plate 2 has a horizontal through hole. Two positioning shafts 3 are symmetrically placed in the mounting hole. A mounting sleeve 4 is installed at the center of the positioning plate 2. A drive rod 5 is vertically arranged in the mounting sleeve 4. The bottom of the drive rod 5 abuts against the abutting ends 31 of the two positioning shafts 3. When the drive rod 5 moves downward, it drives the two positioning shafts 3 to move synchronously in opposite directions and aligns the working ends 32 of the two positioning shafts 3 with the opposite sidewalls of the slot 011 of the workpiece 01. In this embodiment, the workpiece 01 has two slots 011 on the left and right. Therefore, the drilling template 02 is provided with two positioning components 1 on the left and right. After the workpiece 01 is placed in the set position, the drilling template 02 is placed on the workpiece 01. The distance between the two positioning components 1 matches the distance between the two slots 011. Therefore, the positioning component 1 is positioned at the center of the slot 011, and the workpiece 01 can be positioned on the drilling template 02 by the positioning component 1. That is, the center of the workpiece 01 is aligned by the positioning mechanism 1, so that the center of the workpiece 01 and the center of the drilling template 02 are consistent, which is convenient for subsequent processing of the workpiece 01. The positioning plate 2 is installed on the drilling template 02. The lower part of the mounting plate 2 protrudes from the drilling template 02 and is located in the slot 011. A mounting hole is horizontally provided on the mounting plate 2. Two symmetrical positioning shafts 3 are slidably arranged in the mounting hole. A mounting sleeve 4 is provided at the top center of the mounting plate 2. A drive rod 5 is provided in the mounting sleeve 4. The bottom of the drive rod 5 abuts against the abutting end 31 of the two positioning shafts 3. When the drive rod 5 moves downward, the left positioning shaft 3 moves to the left and the right positioning shaft 3 moves to the right, so that the working end 32 of the positioning shaft 3 abuts against the side wall of the slot 011. Since the moving stroke of the left positioning shaft 3 and the right positioning shaft 3 is the same, the positioning component 1 can be accurately positioned at the center of the slot 011, which facilitates the subsequent drilling of the workpiece 01.

[0016] See Figure 1-3 In some possible embodiments, the mounting sleeve 4 has an internal thread, and the outer wall of the drive rod 5 is provided with an external thread that matches the internal thread. When the drive rod 5 is rotated, the drive rod 5 moves up and down relative to the mounting sleeve 4. In this embodiment, the drive rod 5 and the mounting sleeve 4 are connected by a thread. Rotating the drive rod 5 allows it to move up and down relative to the mounting sleeve 4, facilitating the contact between the drive rod 5 and the positioning shaft 3.

[0017] See Figure 1-3 In some possible embodiments, the bottom end of the drive rod 5 and the abutment end 31 of the positioning shaft 3 both have a frustum portion; In this embodiment, the bottom of the drive rod 5 is a frustum, and the abutment end 31 of the positioning shaft 3 is also a frustum. In this way, the frustums are guided by an inclined plane, and the drive rod 5 moves downward, driving the two positioning shafts 3 to move in opposite directions.

[0018] See Figure 1-3 In some possible embodiments, a cover plate 9 is provided on the side wall of the positioning plate 2, the actuating end 32 of the drive rod 3 passes through the cover plate 9, a stepped surface is provided on the positioning shaft 3, and an elastic member 6 is sleeved on the positioning shaft 3. One end of the elastic member 6 abuts against the stepped surface, and the other end abuts against the cover plate 9. In this embodiment, in order to achieve automatic reset after the positioning shaft 3 moves, an elastic element 6 is provided. When the positioning shaft 3 contacts the side wall of the slot 011, the elastic element 6 is in a compressed state. When the drive rod 5 does not apply force to the positioning shaft 3, the positioning shaft 3 resets by relying on the elastic element 6, thereby separating the workpiece 01 from the drill template 02.

[0019] See Figure 1-3 In some possible embodiments, a toggle lever 7 is vertically connected to the top of the drive rod 5, and rotating the toggle lever 7 drives the drive rod 5 to rotate. In this embodiment, the drive lever 5 can be rotated forward or backward by rotating the lever 7, so as to realize the lifting and lowering movement of the drive lever 5.

[0020] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
