Description

Technical Field

[0001] The utility model relates to the technical field of sewing equipment, in particular to an efficiency-enhancing device for producing tooth lifting frames. Background Art

[0002] A feed dog lift is a component in a sewing machine that raises and lowers the feed dogs. Connected to the machine's main shaft, it mechanically moves the feed dogs up and down, thereby moving the material to sew. The design and adjustment of the feed dog lift are crucial to the machine's sewing performance and its ability to adapt to different materials.

[0003] Most of the current dental lifts are processed using CNC technology in machining centers. Since the dental lift is a special-shaped workpiece, during the processing, it is necessary to process multiple through holes with different hole spacings on the surface of the dental lift, and the surface must be processed and polished, resulting in many processing steps. In addition, the dental lift itself has poor rigidity and needs to be fixed during processing. Therefore, it needs to be repeatedly adjusted according to different processes. As a result, in the process of mass processing, the position of the dental lift needs to be repeatedly adjusted, which is more troublesome and reduces the processing efficiency.

[0024] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0025] See attached Figure 1-Figure 3 As shown, an efficiency-enhancing device for producing a tooth lifting frame comprises a mounting plate 1 mounted on a rotating shaft, a clamp plate 2 is fixedly mounted on the upper surface of the mounting plate 1, a fixing part 3 is fixedly mounted on the bottom of the front side of the clamp plate 2, the fixing part 3 is composed of a fixing seat 31 and a mounting seat 32, the diameter of the mounting seat 32 is smaller than the fixing seat 31, and the diameter of the fixing seat 31 is larger than the size of the corresponding end of the tooth lifting frame 4, the tail end of the fixing seat 31 is fixedly connected to the front side of the clamp plate 2, the mounting seat 32 is fixedly mounted on the front end of the fixing seat 31, a threaded groove is provided at the front end of the mounting seat 32, and the front end of the mounting seat 32 is threadedly connected with a first clamping bolt 8, and the tooth lifting frame 4 is mounted on the surface of the mounting seat 32 through the first clamping bolt 8, a splint mounting rod 14 is fixedly mounted on the front side of the clamp plate 2 and at the top of the fixing part 3, an auxiliary positioning part is fixedly mounted on the top end of the front side of the clamp plate 2, and a splint 5 is detachably provided at the front end of the splint mounting rod 14.

[0026] The tooth lifting frame 4 is placed on the fixture plate 2, and the tooth lifting frame 4 is installed on the mounting seat 32 through the large hole that has been processed, and the tooth lifting frame 4 and the mounting seat 32 are fixed by the first clamping bolt 8. Then the other end of the tooth lifting frame 4 is fixed by the auxiliary positioning part, and the splint 5 is installed on the front of the tooth lifting frame 4 through the cooperation of the second clamping bolt 9 and the splint mounting rod 14 to assist in fixing the top of the tooth lifting frame 4.

[0027] The top end of the splint 5 is threadedly connected to a third clamping bolt 11, and the interior of the splint 5 is provided with a second clamping bolt 9 that is compatible with the splint mounting rod 14. The interior of the splint 5 is provided with a sliding groove for the second clamping bolt 9 to slide horizontally. The size of the second clamping bolt 9 is larger than the size of the splint mounting rod 14, and the interior of the second clamping bolt 9 is provided with an internal thread groove that is compatible with the surface thread of the splint mounting rod 14.

[0028] After the tooth lifting frame 4 is placed on the clamp plate 2, the splint 5 is attached to the front of the tooth lifting frame 4. Then, when the second clamping bolt 9 is threadedly connected to the splint mounting rod 14, the splint 5 gradually moves inward to the tooth lifting frame 4, cooperating with the clamp plate 2 to clamp and fix the tooth lifting frame 4.

[0029] A support screw 13 is threadedly connected to the left side of the interior of the clamping plate 5 , and the length of the support screw 13 is greater than the length of the clamping plate mounting rod 14 .

[0030] The support screw 13 can adjust the height of the left end of the splint 5. The range of height adjustment should make the left end of the splint 5 1 mm higher than the right end of the splint 5, thereby ensuring that the right end of the splint 5 presses the groove side plane of the tooth lifting frame 4. However, since the groove side pressing surface of the tooth lifting frame 4 is very narrow, in order to ensure the clamping position of the splint 5, the upper splint mounting rod 14 of the clamp plate 2, when the splint 5 is installed, the second clamping bolt 9 in the splint 5 is adjusted to the position in the sliding groove, and the second clamping bolt 9 is fixed to the splint mounting rod 14 through threads, so that the splint 5 can be installed.

[0031] Furthermore, the auxiliary positioning part includes a positioning pin 12 fixedly installed on the top of the front side of the clamp plate 2, and an adjusting block 7 is threadedly connected to the inside of the clamp plate 2 and at the top of the positioning pin 12. A pad 6 is fixedly installed on the front side of the clamp plate 2 and at one side of the positioning pin 12. The height difference between the fixing part 3 and the pad 6 is the same as the plane distance from the large hole end face of the tooth lifting frame 4 to the groove side. A tightening bolt 10 capable of adjusting the position of the adjusting block 7 is provided on the back side of the clamp plate 2. The width of the pad 6 is less than 1 mm of the thickness of the tooth lifting frame 4, and the width of the splint 5 is less than 1 mm of the thickness of the tooth lifting frame 4. The design of less than 1 mm avoids the problem of the tooth lifting frame 4 being interfered with by the splint 5 and the pad 6 during processing.

[0032] A threaded hole matching the tightening bolt 10 is provided inside the fixture plate 2, and the rear end of the adjustment block 7 is fixedly connected to the front end of the tightening bolt 10. A groove for the adjustment block 7 to move is provided on the front of the fixture plate 2.

[0033] When the support bolt 10 is rotated, the adjustment block 7 can be adjusted to move horizontally, and the third clamping bolt 11 can be used to clamp the top of the dental lifting frame 4 to prevent the dental lifting frame 4 from shaking when processing small holes or drilling grooves, resulting in errors in processing accuracy and affecting the pass rate of the dental lifting frame 4.

[0034] Furthermore, the four corners of the upper surface of the mounting plate 1 are vertically penetrated with connection holes for installation. The mounting plate 1 is installed on the rotating shaft of the machining center through the connection holes. The connection holes facilitate the installation of the mounting plate 1 on the machine tool of the machining center.

[0035] After the dental lifting frame 4 is fixed, the mounting plate 1 is fixed on the rotating axis of the machining center, so that the machining center can process the corresponding surfaces of the dental lifting frame 4, and multiple processes can be completed at one time in the machining center. During this process, the dental lifting frame 4 does not need to be disassembled repeatedly, and the efficiency is improved by 60%. The dental lifting frames 4 produced are of consistent size, and the qualified rate has increased from 80% in the past to 99% now, which enables one person to operate multiple machines and saves labor costs.

[0036] Attached Figure 4-Figure 5This is the processed tooth lifting frame 4. The shaded part and large hole marked in the figure are the parts that have been processed before the tooth lifting frame 4 is fixed by the fixture plate 2. The remaining small holes and grooves need to be fixed on the device and then processed by the machining center.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
