Description

Technical Field

[0001] This utility model relates to the technical field of machining machines, and in particular to the technical scope of an auxiliary accessory for machining machines. Background Technology

[0002] Multi-station vises or devices are becoming increasingly widespread and important in the current machining field. This is mainly driven by modern machining trends such as "automated production," "simultaneous processing of multiple parts," and "increasing machine tool uptime."

[0003] Generally speaking, a multi-station vise or device mainly consists of a base with several movable seats that are staggered between several fixed seats. By operating the bolts on the several wedges provided on the movable seats, the movable seats can be driven to clamp several workpieces. For example, Chinese Utility Model Patent No. CN216464052U, "A Multi-station Vise", is an example.

[0004] However, in existing multi-station vises or devices, the movable blocks and wedges are separate when detached from the base and not in use, and cannot be combined in pairs. In other words, the movable blocks or wedges are easily lost after being detached from the base. If lost, the multi-station vise or device often loses the clamping of one or more workpieces at one or more stations, which is quite troublesome. Therefore, based on the above-mentioned shortcomings of existing multi-station vises or devices, there is a real need for improvement. Utility Model Content

[0005] Therefore, in view of the problems existing in the above-mentioned multi-station vises or devices, the main purpose of this utility model is to provide a grouped multi-station fine-tuning fixture structure; the secondary purpose of this utility model is to provide a multi-station fine-tuning fixture structure that is not prone to chip jamming; another purpose of this utility model is to provide a multi-station fine-tuning fixture structure that is suitable for processing a large number of micro workpieces.

[0006] To achieve the above objectives, the present invention provides a multi-station fine-tuning fixture structure using the following technical means: a first movable block having a first inclined surface at the inner end of a first body and a first clamping surface at the outer end, and two first ear blocks from the two sides of the first body; a second movable block having a second inclined surface at the inner end of a second body and a second clamping surface at the outer end, and two second ear blocks from the two sides of the second body; two connecting elastic components disposed between the two first ear blocks and the two second ear blocks, such that the first inclined surface and the second inclined surface form a clamping groove; and a wedge block placed in the clamping groove, the wedge block having a connecting hole for placing a connecting bolt; by connecting the bolt to the processing platform, and rotating the connecting bolt to displace the wedge block downward to clamp the clamping groove, the first movable block and / or the second movable block can clamp and fix multiple micro workpieces.

[0007] It further includes at least one jaw plate, which is disposed on the first clamping surface and / or the second clamping surface, and the clamping surface of the jaw plate is provided with a toothed texture.

[0008] It also includes a parallel shim block group, which is disposed at the bottom of the first movable block and the second movable block.

[0009] Each of the elastic components is provided with a protective tube, a spring and a connecting hanger. The two ends of the protective tube are inserted into the inner side of the two countersunk holes of each of the first ear block and each of the second ear block, while the connecting hanger is provided on the outer side of the two countersunk holes to facilitate hanging the spring.

[0010] The connecting pendant is configured as a protruding round head extending into a stepped rod, and the stepped rod is provided with a hanging hole, and the protruding round head is provided with a cross-section.

[0011] The outer end face of the protruding round head of the connecting pendant is flush with or does not protrude from the first clamping surface of the first movable block and the second clamping surface of the second movable block.

[0012] The wedge block is provided with a first clamping surface and a second clamping surface respectively corresponding to the first inclined surface and the second inclined surface; in addition, a chip-proof and dust-proof scraper is provided on the top surface of the first movable block and the second movable block.

[0013] Both the first inclined surface and the second inclined surface are provided with a guide groove, and the first pressing surface and the second pressing surface are each provided with a guide pin, a guide block, a guide post or a guide bolt corresponding to the guide groove.

[0014] The first inclined surface and the second inclined surface are respectively provided with a groove at the bottom of the connecting bolt.

[0015] The first clamping surface and / or the second clamping surface are provided with a toothed pattern, and the engagement hole of the wedge is provided as an elongated fish-eye hole.

Detailed Implementation

[0032] like Figure 1 and Figure 7 As shown, this utility model provides a multi-station fine-tuning fixture structure, which is used to clamp multiple micro workpieces for processing. The multi-station fine-tuning fixture structure A includes: a first movable block 1, a second movable block 2, a clamping groove 3, two connecting elastic components 4, a wedge block 5, and a connecting bolt 6. The above components are described below with reference to the accompanying drawings.

[0033] like Figures 2 to 4 As shown, the first movable block 1 has a first inclined surface 12 on the inner end of its first body 11, a first clamping surface 13 on its outer end, and two first ear blocks 14 on the two sides of the first body 11.

[0034] like Figures 2 to 4 As shown, the second movable block 2 has a second inclined surface 22 on the inner end of its second body 21 and a second clamping surface 23 on its outer end. Two second ear blocks 24 are provided on the two sides of the second body 21. A toothed pattern is provided on the first clamping surface 13 and / or the second clamping surface 23 to increase the clamping friction of the first clamping surface 13 and the second clamping surface 23.

[0035] like Figure 2 , Figure 4 and Figure 6 As shown, the clamping groove 3 is designed to bring the first movable block 1 closer to the second movable block 2, so that the first inclined surface 12 and the second inclined surface 22 are opposite to each other and form the clamping groove 3; in addition, a guide groove 121 and a guide groove 221 are respectively provided on the first inclined surface 12 and the second inclined surface 22; and an escape groove 15 and an escape groove 25 are respectively provided below the first inclined surface 12 and the second inclined surface 22 corresponding to the connecting bolt 6, so as to avoid interference between the lower part of the first movable block 1 and the second movable block 2 and the connecting bolt 6 when the first movable block 1 moves closer to the second movable block 2.

[0036] like Figure 2 , Figure 3 and Figure 5 As shown, the two-joint elastic components 4 are disposed between the two first ear blocks 14 and the two second ear blocks 24, such that the first inclined surface 12 and the second inclined surface 22 form the clamping groove 3; each of the two-joint elastic components 4 is provided with a protective tube 41, a spring 42 and a connecting hanger 43, wherein the two ends of the protective tube 41 are inserted into the inner side of a countersunk hole 141 and a countersunk hole 241 provided in each of the first ear blocks 14 and each of the second ear blocks 24, and each connecting hanger 43 is disposed on the outer side of the countersunk hole 141 and the countersunk hole 241 respectively.

[0037] Each of the connecting pendants 43 is provided with a protruding rounded head 431 extending into a stepped rod 432, and the stepped rod 432 is provided with a hanging hole 433, which provides hooks at both ends of the spring 42 for hooking, so as to hang the spring 42. The protruding rounded head 431 is provided with a cross-section 434, such as... Figure 1 As shown, the cut surface 434 is flat against the side of the first movable block 1 or the second movable block 2, which can prevent the connecting hangers 43 from rotating without reason; in addition, the outer end face of the protruding round head 431 is cut flush with or does not protrude from the first clamping surface 13 of the first movable block 1 and the second clamping surface 23 of the second movable block 2, so as to facilitate the tiger mouth plate to be set on the first clamping surface 13 and / or the second clamping surface 23.

[0038] like Figure 2 and Figure 4 As shown, the wedge 5 is placed in the clamping groove 3, and the wedge 5 is provided with a connecting hole 53 for placing a connecting bolt 6. The connecting hole 53 is preferably an elongated fish-eye hole, thereby extending the fine-tuning and fixing range of this utility model. The wedge 5 is provided with a first clamping surface 51 and a second clamping surface 52 respectively corresponding to the first inclined surface 12 and the second inclined surface 22. In addition, the first clamping surface 51 and the second clamping surface 52 are provided with a guide pin 54, a guide block, a guide post or a guide bolt respectively corresponding to the guide groove 121 and the guide groove 221. The aforementioned guide pins 54, etc. are all provided to be inserted into the guide groove 221. In addition to guiding the wedge 5 to move up and down, the elastic force of the springs 42 can also be used to prevent the wedge 5 from dislodging from the clamping groove 3 and being lost.

[0039] Therefore, this utility model provides a preferred solution for a multi-station fine-tuning fixture structure that can be implemented in groups, such as... Figure 1 , Figure 4 and Figure 5 As shown, it mainly uses the two combined elastic components 4 to combine the first movable block 1, the second movable block 2 and the wedge block 5 together. That is, in the unused state of the multi-position fine-tuning fixture structure A of this utility model, the first movable block 1, the second movable block 2 and the wedge block 5 can be kept together as a group, making it less likely to lose any of the components.

[0040] When using the multi-station fine-tuning fixture structure A of this utility model, such as... Figure 6 and Figure 7 As shown, by attaching the front end of the connecting bolt 6 to the processing platform 7, and rotating the connecting bolt 6 clockwise to displace the wedge 5 downward to clamp the clamping groove 3, the first clamping surface 51 of the wedge 5 will press against the first inclined surface 12 of the first movable block 1, while the second clamping surface 52 will press against the second inclined surface 22 of the second movable block 2. In other words, rotating the connecting bolt 6 clockwise to displace the wedge 5 downward causes the first movable block 1 and the second movable block 2 to simultaneously move laterally away from each other, so that the first movable block 1 and / or the second movable block 2, together with the fixing block 72, can clamp and fix multiple miniature workpieces 71. For example, such as Figure 7 and Figure 8 As shown, this is an embodiment of the fine-tuning fixture structure for a two-station workstation of this utility model, in which a single fixture of this utility model is used in conjunction with two fixing blocks 72 to clamp two miniature workpieces 71 for machining; and it can also be used as follows Figure 9 and Figure 10 As shown, two fixtures of this invention are used in conjunction with three fixing blocks 72 to clamp two miniature workpieces 71 for machining.

[0041] Similarly, when the connecting bolt 6 is rotated in reverse to allow the wedge block 5 to move upward and no longer clamp the clamping groove 3, the restoring force of each spring 42 will cause the first movable block 1 and the second movable block 2 to move laterally together simultaneously. That is, the first inclined surface 12 of the first movable block 1 will remain in contact with the first clamping surface 51 of the wedge block 5, and the second inclined surface 22 of the second movable block 2 will remain in contact with the second clamping surface 52 of the wedge block 5, so that the first movable block 1 and / or the second movable block 2 will be released and no longer clamp and fix the multiple micro workpieces 71, so as to facilitate the removal of the multiple micro workpieces 71.

[0042] Please see Figure 1 and Figure 11 As shown, the multi-station fine-tuning fixture structure A of this utility model can be further provided with at least one jaw plate 8. The jaw plate 8 can be provided with several countersunk screws 811 and can be set on the first clamping surface 13 and / or the second clamping surface 23 of this utility model. The clamping surface 81 of the jaw plate 8 is used to extend the clamping of larger micro workpieces. At the same time, a parallel shim block group 9 can also be added. The parallel shim block group 9 can be provided with several countersunk screws 91 and can be set on the bottom surface of the first movable block 1 and the second movable block 2. Furthermore, on the top surface of the first movable block 1 and the second movable block 2, a chip and dust prevention scraper 92 is provided with fastening screws 921. The chip and dust prevention scraper 92 can prevent chips and dust from entering the first clamping surface 51 and the second clamping surface 52 of the wedge block 5, thereby avoiding excessive wear of the wedge block 5 and extending the service life of this utility model.

[0043] Specifically, this utility model is equipped with a tiger's mouth plate 8, which is set on the first clamping surface 13 and / or the second clamping surface 23, to expand the width dimension of the micro workpiece that this utility model can clamp, and the parallel shim block group 9 is set on the bottom surface of the first movable block 1 and / or the second movable block 2 to expand the height dimension of the micro workpiece that this utility model can clamp, so as to achieve the purpose of this utility model being applicable to the processing of a wide range of micro workpiece sizes.
