Description

Technical Field

[0001] This utility model relates to the technical field of machining machines, and more particularly to the technical scope of a center vise for machine tool accessories with variable processing positions. Background Technology

[0002] Multi-station vises 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 "improving machine tool uptime."

[0003] Generally speaking, a multi-station vise mainly consists of a base with several wedge-shaped retainers (OK-VISE) that are staggered between several fixed seats. By tightening the bolts of these wedge-shaped retainers, the two clamping blocks can be driven to clamp several workpieces. For example, Chinese Utility Model Patent No. CN216464052U, "A Multi-station Vise", is an example.

[0004] However, the current multi-station vises provide a fixed number and size of workpieces for each processing session, resulting in a complete lack of flexibility in their use. In particular, the installation position of the wedge retainer is fixed and cannot be changed, thus preventing the expansion of its functions and performance. In other words, the current multi-station vises can only be used to process workpieces of one size. Therefore, manufacturers must prepare many sets of multi-station vises to process workpieces of different sizes, which is not economical. Therefore, the current multi-station vises do need to be improved. Utility Model Content

[0005] Therefore, considering the lack of flexibility in the use of existing multi-station vises, the main objective of this invention is to provide a center vise with better expandability and flexibility, capable of changing multiple machining positions, and its wedge-shaped retainer. A secondary objective is to provide a wedge-shaped retainer whose installation position can be arbitrarily changed. Another objective is to provide a center vise with a variety of machining positions that allows for convenient and rapid workpiece clamping operations. A further objective is to provide a center vise with a variety of machining positions that allows for easy planning of machining position clamping configurations.

[0006] To achieve the above objectives, this utility model employs the following technical means: This utility model provides a wedge-shaped fastener, comprising: a V-shaped block with a through hole; two side clamping blocks placed on both sides of the V-shaped block; two tension springs disposed between the two side clamping blocks; a first lower fixing block having a first wing on each side of the block and a screw hole at the top of the block; and a bolt that passes through the through hole in the V-shaped block and is then fixed to the screw hole in the first lower fixing block.

[0007] Each of the two tension springs is provided with a protective tube on its exterior, and the first lower fixing block is a T-shaped block.

[0008] A guide post and a guide groove are respectively provided between the inclined surfaces on both sides of the V-shaped block and the two clamping blocks.

[0009] An elastic washer is provided between the head of the bolt and the through hole, and a compression spring is provided below the bolt, with the compression spring located between the V-block and the first lower fixing block.

[0010] This utility model provides a center vise with multiple adjustable processing positions, comprising: a base, on the top surface of which is provided a slide rail, and on the belly of the base is provided a receiving groove, and on the receiving groove are two opposing recesses; two clamps, disposed on both sides of the base, and each clamp further comprising a movable block, a second lower fixing block and a fastener, wherein the movable block is placed on the slide rail of the base, and the second lower fixing block is placed inside the receiving groove of the base and embedded... The fastener is inserted into the two recessed grooves provided therein, and the fastener passes through the movable block and is connected to the second lower fixed block; a transmission screw is provided inside the receiving groove provided in the base, and its two ends are respectively connected to the second lower fixed blocks provided in each of the clamps; and at least one wedge-shaped retainer is used, and the first lower fixed block is also placed in the receiving groove, and its first wing is embedded in the two recessed grooves, and the at least one wedge-shaped retainer is connected to the slide rail provided in the base by means of the bolt.

[0011] The second lower fixing block is configured as a cross-shaped block with two second wings, and the length of the first lower fixing block is shorter than the length of the second lower fixing block.

[0012] The two second wings are embedded in the two recesses.

[0013] The transmission screw has a first external thread and a second external thread with different transmission directions, and both ends of the transmission screw are hexagonal.

[0014] The device also includes a detachable center block, which is positioned in the middle of the slide rail on the base. The detachable center block is connected to two screw holes in the middle of the slide rail by two screws. The bottom of the detachable center block has a groove corresponding to the slide rail, and each movable block has a sliding groove corresponding to the slide rail.

[0015] The base has a size scale, a long groove and several connecting screw holes on its two sides, and each of the connecting screw holes is provided for mounting a vise positioner.

[0016] Therefore, by employing the above-mentioned technical means, this utility model can achieve the following effects compared to the prior art:

[0017] 1. This utility model, through the detachable center block, the two clamps located on the left and right sides of the base, and the at least one wedge-shaped retainer, can be configured into a central vise with multiple processing positions. It can provide processing positions from 1 to 16 or more that can be easily planned and changed, and is suitable for clamping and processing both block and strip workpieces. This allows the multi-position vise to no longer be limited to processing workpieces of a single size, with excellent expandability and great flexibility. One vise can replace multiple vises, making this utility model vise economical and affordable.

[0018] 2. The wedge-shaped clamp of this utility model, by means of the bolt and the first lower fixing block, can clamp and fix the workpiece at any position on the base slide rail to perform processing, thereby realizing a center vise that can be changed to a variety of processing positions.

[0019] 3. This utility model features a central vise function combined with at least one wedge-shaped retainer, and each of the vise positioners can be added to the side of its base. In other words, this utility model can use the clamping surfaces of the two vises as the reference surfaces for workpiece positioning and clamping. If possible, each of the vise positioners can also be used to position another reference surface (non-clamping surface) of the workpiece, allowing the operator to quickly clamp and fix all workpieces to the processing position by simply operating the transmission screw, each of the fasteners, each of the bolts, each of the screws or combinations thereof, thereby improving work efficiency. At the same time, the bolts of the wedge-shaped retainer, combined with the use of the elastic washer and the compression spring, can prevent the clamping force from loosening during the processing operation.

[0020] 4. This utility model has the size scale on both sides of its base, which allows the operator to easily plan how many vise bases and wedge retainers are needed based on the size of the workpiece to be processed and by visually referring to the size scale. Attached Figure Description

Detailed Implementation

[0037] like Figure 1 As shown, this utility model relates to a center vise with multiple variable machining positions and its wedge retainer, which mainly provides a variety of clamping methods for multiple workpieces for machine tool processing. The center vise A with multiple variable machining positions includes: a base 1, a detachable center block 2, two clamps 3, a transmission screw 4 and / or at least one wedge retainer 5; the above components are illustrated in the following figures.

[0038] like Figure 2 , Figure 3 and Figure 15 As shown, the base 1 has a slide rail 11 on the top surface of the body 10, and a receiving groove 12 on the belly of the body 10. The receiving groove 12 has two opposing recessed grooves 13. The two sides of the base 1 are respectively provided with a size scale 15, a long groove 16 and several connecting screw holes 17. Each long groove 16 provides a pressure plate 94 for use, and each connecting screw hole 17 provides a vise positioner 6 for installation.

[0039] like Figure 2 and Figure 3 As shown, the detachable center block 2 is fixed in the middle position of the slide rail 11 provided on the base 1; the bottom of the detachable center block 2 is provided with a groove 21, and the detachable center block 2 is fixed to the two screw holes 14 provided in the middle position of the slide rail 11 by means of two screws 22; if necessary, the detachable center block 2 can be removed and temporarily not used.

[0040] like Figure 2 , Figure 3 and Figure 7 As shown, the two clamps 3 are located on both sides of the base 1. Each clamp 3 further includes a movable block 31, a second lower fixing block 32, and a fastener 33. Each movable block 31 has a sliding groove 311 at its bottom for placement on the slide rail 11 provided on the base 1. Each second lower fixing block 32 is placed inside the receiving groove 12 provided on the base 1. Each second lower fixing block 32 is configured to have two second wings 321. The cross-shaped block has two second wings 321 embedded in its two recessed grooves 13, and each fastener 33 passes through the movable block 31 and is connected to the screw hole on the top surface of each second lower fixing block 32. When each fastener 33 is tightened with a tool, each second lower fixing block 32 moves upward, so that the two second wings 321 clamp the inner wall of the two recessed grooves 13, thereby fixing the two clamps 3 to the slide rail 11 of the base 1.

[0041] like Figure 2 and Figure 3 As shown, the transmission screw 4 is located in the receiving groove 12 of the base 1, and the transmission screw 4 is provided with a first external thread 41 and a second external thread 42 with different transmission directions. These are respectively connected to the internal threads of the second lower fixing blocks 32 of each clamp 3. Both ends of the transmission screw 4 are provided with a hexagonal portion 43, so that the transmission screw 4 can be rotated by a tool through the hexagonal portion 43, thereby driving the two second lower fixing blocks 32 and driving the two clamps 3 to slide closer or further apart on the slide rail 11 of the base 1.

[0042] like Figures 2 to 6 , Figure 8 As shown, the at least one wedge-shaped retainer 5 mainly comprises a first lower fixing block 50, a bolt 51, a V-shaped block 52, two side clamping blocks 53, and two tension springs 54. The V-shaped block 52 has a through hole 521, and the two side clamping blocks 53 are positioned on both sides of the V-shaped block 52. The two tension springs 54 are connected between the four lugs 532 of the two side clamping blocks 53, and each of the two tension springs 54 is externally fitted with a protective device. The tube 55 protects the two tension springs 54; the bolt 51 passes through an elastic washer 56, a through hole 521 provided in the V-block 52 and a compression spring 57 from top to bottom, and is then connected to a screw hole 502 provided in the first lower fixing block 50. The aforementioned elastic washer 56 and compression spring 57 can prevent the bolt 51 from loosening when the workpiece 7 is being processed, thus preventing the wedge retainer 5 from losing its clamping force.

[0043] like Figure 3 , Figure 6 and Figure 8As shown, the first lower fixing block 50 is placed in the receiving groove 12 of the base 1, and the first lower fixing block 50 is a T-shaped block with two first wings 501 on both sides of a block 500, and the two first wings 501 are embedded in the two recesses 13. The length of the first lower fixing block 50 must be shorter than the length of the second lower fixing block 32 to avoid interference between the first lower fixing block 50 and the transmission screw 4 when the first lower fixing block 50 is in operation.

[0044] Furthermore, a guide post 522 and a guide groove 531 are respectively provided between the inclined surfaces on both sides of the V-block 52 and the two clamping blocks 53. This facilitates the upward movement of the first lower fixing block 50 when the bolt 51 is tightened, allowing the two first wings 501 to clamp the inner walls of the two recessed grooves 13, thereby fixing the wedge-shaped retainer 5 onto the slide rail 11 of the base 1. At the same time, the inclined surfaces on both sides of the V-block 52 are used to laterally push the two clamping blocks 53 outward to clamp the workpieces 7 located on both sides of the wedge-shaped retainer 5. If the bolt 51 is loosened, the two clamping blocks 53 move inward due to the restoring force of the two tension springs 54, while their inclined surfaces push against the V-block 52 to move upward. The external thread of the bolt 51 will cause the first lower fixing block 50 to move downward, thereby simultaneously releasing the clamping of the wedge-shaped retainer 5.

[0045] Therefore, this utility model provides a preferred solution for a center vise with multiple processing positions, wherein the center vise A with multiple processing positions can be configured to provide processing of a variety of workpieces 7 by means of the detachable center block 2, the two clamps 3 located on the left and right sides of the base 1 and the at least one wedge-shaped retainer 5.

[0046] For example, such as Figure 9 As shown, the detachable center block 2 and at least one wedge-shaped retainer 5 are temporarily removed. The central vise A of this utility model, which can be configured to handle multiple processing positions, forms a central vise to provide a processing position for a single workpiece 7. That is, the operator first loosens the fasteners 33 of the two clamps 3, and then uses a wrench to control the rotation of the transmission screw 4, so that the two clamps 3 slide and come closer to each other on the slide rail 11 of the base 1 to clamp the single workpiece 7. Then, the fasteners 33 are tightened to position and fix the two clamps 3, and then the workpiece 7 can be sent into the machine tool for processing.

[0047] like Figure 10The diagram shows an implementation where the detachable center block 2 is replaced with the wedge-shaped retainer 5 to provide a machining station for two workpieces 7. First, the transmission screw 4 is rotated using a wrench, causing the two clamps 3 to slide closer or further apart to adjust the reference surface for clamping and positioning the two workpieces 7. Then, the fasteners 33 are tightened to position and fix the two clamps 3. Next, the wedge-shaped retainer 5 is tightened with its bolts 51 to press down the V-block 52, forcing the clamping surfaces of the two side clamping blocks 53 to expand laterally and clamp and fix the two workpieces 7. The workpieces 7 can then be fed into the machine tool for machining. After machining, the bolts 51 are loosened, and the workpieces 7 can be released and removed. If the two workpieces 7a are wide, such as... Figure 11 As shown, two central vises A of this utility model, which can be used side by side to fix and clamp the two workpieces 7a for processing.

[0048] like Figure 12 The diagram shows an implementation where the detachable center block 2 is replaced with two wedge-shaped retainers 5 to provide a machining station for three workpieces 7. First, the transmission screw 4 is rotated using a wrench, causing the two clamps 3 to slide closer or further apart to adjust the reference surface for clamping and positioning the three workpieces 7. Then, the two wedge-shaped retainers 5 are tightened with their bolts 51 to press down the V-block 52, thereby forcing the clamping surfaces of the two side clamping blocks 53 to expand laterally and clamp the three workpieces 7. They can then be sent into the machine tool for machining. After machining is completed, the bolts 51 are loosened to release and remove each workpiece 7.

[0049] like Figure 13 As shown, similarly, the detachable center block 2 is paired with two wedge-shaped retainers 5 to provide a processing station for four workpieces 7. First, the transmission screw 4 is rotated using a wrench, causing the two clamps 3 to slide closer or further apart to adjust the reference surface for clamping and positioning the four workpieces 7. Then, the two wedge-shaped retainers 5 are tightened with their bolts 51 to press down the V-block 52, forcing the clamping surfaces of the two side clamping blocks 53 to expand laterally and clamp the four workpieces 7. If the four workpieces 7 are strip-shaped workpieces 7a, such as... Figure 14 As shown, the four workpieces 7a are fixedly clamped and processed using two central vises A of this utility model with multiple variable processing positions side by side.

[0050] Please see Figure 15As shown, this is another embodiment of the vise of the present invention, which includes: a base 8 with several mating holes 81 close to its outer perimeter; a column 9 with its bottom attached to the base 8, and the column 9 having several mating surfaces 91 (preferably 2 to 8 mating surfaces 91), and the several mating surfaces 91 having several mating screw holes 92; and several center vises, which are multiple center vises A of the present invention that can be used to change various processing positions, and the several center vises are respectively erected side by side on the several mating surfaces 91 of the column 9 by several mating screws 93 and pressure plates 94, so as to clamp and fix more strip workpieces 7a for processing.
