Description

Technical Field

[0001] The present application relates to the technical field of mechanical manufacturing processes, and in particular to a multi-process and multi-station clamping tool. Background Art

[0002] Aircraft engine brackets require the use of a variety of milling cavity and milling surface tooling for milling processing. The same type of aircraft engine structure brackets have different external contours. The milling cavity and milling surface of a bracket are generally clamped using a vise, and a single vise is used to process a single part.

[0003] The vise occupies a large space, affecting the normal use of other tooling. A single vise can only process a single part. The operator's cycle time is not long enough when operating multiple machines, and the processing efficiency is low. At the same time, when changing products, the operation is more complicated, and it is necessary to adjust the position of the vise's movable jaws and manufacture pads of different heights. Utility Model Content

[0004] In view of this, the main purpose of this application is to provide a multi-process and multi-station clamping tool.

[0005] The present application provides a multi-process and multi-station clamping tool, which includes:

[0006] A rectangular base, the upper surface of which includes two first T-shaped grooves parallel to one side of the rectangular base;

[0007] Two vertical plates parallel to the first T-slots are arranged on the upper surface of the rectangular base and outside the two first T-slots, second T-slots parallel to the first T-slots are arranged on opposite sides of the two vertical plates, and positioning grooves are arranged on the tops of the vertical plates;

[0008] A support plate is located between the two first T-slots and is arranged on the upper surface of the rectangular base in parallel with the vertical plate. A groove is arranged on the top of the support plate, and a plurality of holes are arranged side by side on the groove for installing an OK clip.

[0009] The rectangular base, the support plate and at least one vertical plate form a receiving cavity;

[0010] A cushion block is detachably mounted in the accommodation cavity, and two sides of the cushion block facing the rectangular base and the vertical plate are provided with T-shaped blocks matching the first T-shaped slot and the second T-shaped slot, and the cushion block can be slidably mounted in the accommodation cavity through the cooperation between the T-shaped block and the first T-shaped slot and the second T-shaped slot;

[0011] The positioning rod is arranged in the positioning groove at the top of the vertical plate and extends toward one side of the second T-shaped groove of the vertical plate.

[0012] As shown above, the T-block on the pad can adapt to the first T-slot on the rectangular base and the second T-slot on the vertical plate, and slide along the first T-slot and the second T-slot at the same time. The pad supports the part, and the positioning of the part is completed by the positioning rod installed on the vertical plate. Since there is a row of holes with small intervals on the support plate, the installation position of the OK clamp can be freely adjusted according to the size of the part. The part can be clamped by the OK clamp and the pad. Multiple pads can be installed on the rectangular base, and multiple parts can also be clamped. Different pads can be used to achieve the effect of processing multiple parts, multiple processes, and multiple workstations with a single tool, which greatly saves tooling costs and improves the use efficiency of tooling. At the same time, it also reduces the part changeover time and further improves the utilization rate of machine tools.

[0013] Optionally, a stepped structure is provided on the top of the pad, wherein a first step surface of the stepped structure is higher than a second step surface, and the second step surface is used for placing parts, and the first step surface is close to the vertical plate.

[0014] From the above, since the first step surface is higher than the second step surface, the first step surface utilizes the height difference to cooperate with the OK clamp to clamp the parts, and the parts are supported by the second step surface. The multi-type and multi-process processing of the parts is realized through the first-level stepped structure of the pad.

[0015] Optionally, the positioning rod includes a rod shaft and a fixed block, the fixed blocks are assembled on both sides of the rod shaft, wherein: an axial hole is set at one end of the rod shaft; a first through hole is set on two opposite surfaces of the upper end of the fixed block, and the first through hole is aligned with the axial hole on the rod shaft.

[0016] From above, the positioning rod is composed of a rod shaft and a fixed block. The two fixed blocks are respectively located on both sides of the rod shaft. The first through holes on the two fixed blocks are concentrically arranged with the rod shaft holes to facilitate the rotation of the rod shaft around the fixed blocks. The rod shaft extends out of the side of the vertical plate with the second T-slot to provide positioning services for the parts that need to be clamped.

[0017] Optionally, second through holes are provided on the other two opposite surfaces at the lower end of the fixing block, and the through hole directions of the first through holes and the second through holes located on different horizontal planes are perpendicular, and the positioning rod is fixed on the vertical plate through the second through holes.

[0018] From above, the second through hole at the lower end of the fixed block fixes the rod shaft on the vertical plate. Under the action of the positioning groove at the top of the vertical plate, the rotation degree of the rod shaft around the fixed block can be limited, so that the rod shaft plays a positioning role when it falls into the positioning groove. When replacing parts, the rod shaft can be lifted upward around the fixed block, which provides convenience for removing parts.

[0019] Optionally, the lower surface of the rectangular base is equipped with a mounting base.

[0020] As shown above, the mounting base and the rectangular base are installed by rivets to meet the needs of quick-change tooling. Quick change can be used to complete the assembly and disassembly of parts outside the machine tool, reducing the waiting time of the machine tool downtime.

[0021] Optionally, according to the installation position of the cushion block, a hole adjacent to the cushion block is selected on the support plate to install the OK clip accordingly.

[0022] From above, a row of threaded holes is set in the groove on the support plate, and OK clamps can be installed on the threaded holes, which together with the pads provide horizontal clamping force for the parts. Therefore, the positions of the OK clamps and the pads should be set on the same horizontal line.

[0023] Optionally, the number of first T-slots provided on the rectangular base includes at least two, and the number of first T-slots is an even number.

[0024] As described above, at least two mutually parallel first T-slots, each of which can be used to install and place at least two parts, enable the tooling to provide multiple workstations for multiple parts in the transverse and longitudinal directions.

[0025] Optionally, depending on the type of parts, the sizes of the first step surface and the second step surface of the primary step structure on the top of the pad are different.

[0026] From the above, due to the different sizes of parts of different types, the size of the pads in the Y direction is different, that is, the areas of the first step surface and the second step surface are different, and the size of the pads in the Z direction is different, that is, the height difference between the first step surface and the second step surface is different. Different pads are used to clamp different types of parts to achieve the purpose of multiple processes and quick change of product types.

[0027] Optionally, the pad is provided with mounting grooves on both sides facing the rectangular base and the vertical plate, the mounting grooves are provided with threaded holes, and a through hole is provided on the T-block. The T-block is fixed to the pad by passing a nut through the through hole on the T-block and the threaded hole on the mounting groove.

[0028] From above, two adjacent sides of the cushion block are provided with mounting grooves, and nuts are passed through the through holes on the T-block and the threaded holes on the mounting grooves in sequence to fix the T-block and the cushion block together, providing structural support for the cushion block to slide in the first T-slot and the second T-slot.

[0029] Optionally, the number of the positioning grooves is determined according to the number of parts that need to be clamped.

[0030] From the above, the more parts that need to be clamped, the more positioning rods are needed, and then the more positioning slots need to be set on the vertical plate. The longer the vertical plate is, the more the tooling can clamp multiple parts at the same time.

[0031] To summarize, the multi-process and multi-station clamping tooling provided by the present application can be used to process different types of parts, or to perform different processes on the same part, when different pads are selected, and the T-blocks on the corresponding pads are inserted into the first T-slots on the rectangular base and the second T-slots on the vertical plate to ensure the stable placement of the parts, and the side of the parts are aligned to the positioning rod to complete the positioning of the parts. An M8 two-way OK clamp can be installed on the support plate to clamp the parts. Since there is a row of M8 threaded holes with small intervals on the support plate, the installation position of the M8 two-way OK clamp can be freely adjusted according to the size of the parts. The tooling can clamp multiple parts at the same time in a single processing, and achieve the effect of processing multiple parts, multiple processes, and multiple stations with a single tooling, which greatly saves the tooling cost and improves the efficiency of the tooling. At the same time, there are threaded holes under the rectangular base, which cooperate with the mounting base to install rivets to meet the needs of quick-change tooling. When there are more than two sets of tooling, quick change can be used to complete the assembly and disassembly of parts outside the machine tool, reduce the waiting time of the machine tool downtime, and further improve the utilization rate of the machine tool.

[0049] The present application provides a multi-process and multi-station clamping tool, which includes:

[0050] A rectangular base 1, the upper surface of which includes two first T-shaped grooves 101 parallel to one side of the rectangular base 1;

[0051] Two vertical plates 2 parallel to the first T-slots 101 are mounted on the upper surface of the rectangular base 1 and outside the two first T-slots 101. Second T-slots 201 parallel to the first T-slots 101 are arranged on opposite sides of the two vertical plates 2. Positioning grooves 202 are arranged on the tops of the vertical plates 2.

[0052] The support plate is located between the two first T-slots 101 and is arranged on the upper surface of the rectangular base 1 in parallel with the vertical plate 2. A groove 301 is arranged on the top of the support plate. A plurality of holes are arranged side by side on the groove 301 for installing the OK clip.

[0053] A rectangular base 1, a support plate and at least one vertical plate 2 form a receiving cavity;

[0055] The positioning rod 5 is disposed in the positioning groove 202 at the top of the vertical plate 2 and extends toward one side of the second T-shaped groove 201 of the vertical plate 2 .

[0056] Specifically, the T-block 404 on the pad 4 can adapt to the first T-slot 101 on the rectangular base 1 and the second T-slot 201 on the vertical plate 2, and slide along the first T-slot 101 and the second T-slot 201 at the same time. The pad 4 supports the part, and the positioning of the part is completed by the positioning rod 5 installed on the vertical plate 2. Since there is a row of holes with small intervals on the support plate, the installation position of the OK clamp can be freely adjusted according to the size of the part. The part can be clamped by the OK clamp and the pad 4. Multiple pads 4 can be installed on the rectangular base 1, and multiple parts can also be clamped. Different pads 4 can be used to achieve the effect of processing multiple parts, multiple processes, and multiple workstations with a single tool, which greatly saves tooling costs and improves the efficiency of tooling use. At the same time, it also reduces the part changeover time and further improves the utilization rate of machine tools.

In this embodiment, two parallel first T-slots 101 are arranged on the upper surface of the rectangular base 1. The first T-slots 101 run through this plane, and the direction of the first T-slots 101 is parallel to an edge line of the upper surface of the rectangular base 1. In the upper surface of the rectangular base 1, two vertical plates 2 are installed on both sides of the rectangular base 1, that is, parallel to and close to the edge line. Each vertical plate 2 is provided with a second T-slot 201 facing inward, and the support plate 3 is arranged in the middle position of the two first T-slots 101. The cushion block 4 is inserted into the first T-slot 101 and the second T-slot 201 through the T-block 404 installed thereon and slides along it. The first first T-slot 101 and the first second T-slot 201 are arranged Four pads 4 are installed, and the second first T-slot 101 and the second second T-slot 201 are also installed with four pads 4. The two pads 4 on the same first T-slot 101 jointly support a part. The positioning rod 5 is installed on the vertical plate 2 and supported by the positioning groove 202 on the top of the vertical plate 2. The part extending out of the vertical plate 2 is aligned with the side of the part; a positioning rod 5 is set for every two pads 4, and the two pads 4 on both sides of the support plate 3 are set on the same horizontal line, that is, an OK clamp in the groove 301 on the support plate 3 corresponds to the two pads 4, which greatly utilizes the space and saves the volume occupancy rate of the tooling. The OK clamp can be an M8 bidirectional OK clamp, which can provide force in two directions at the same time, and clamp the part at the same time with the two pads 4 on the same horizontal line on both sides of the support plate 3.

[0058] Optionally, a stepped structure is provided on the top of the cushion block 4 , wherein the first step surface 402 of the stepped structure is higher than the second step surface 403 , and the second step surface 403 is used for placing parts, and the first step surface 402 is close to the vertical plate 2 .

[0059] Specifically, since the first step surface 402 is higher than the second step surface 403, the first step surface 402 utilizes the height difference to cooperate with the OK clamp to clamp the parts, and the parts are supported by the second step surface 403, and the multi-type and multi-process processing of the parts is realized through the first-level stepped structure of the pad 4.

[0060] Optionally, depending on the type of parts, the sizes of the first step surface 402 and the second step surface 403 of the primary step structure at the top of the cushion block 4 are different.

[0061] Specifically, due to the different sizes of parts of different types, the size of the pad 4 in the Y direction is different, that is, the areas of the first step surface 402 and the second step surface 403 are different, and the size of the pad 4 in the Z direction is different, that is, the height difference between the first step surface 402 and the second step surface 403 is different. Different pads 4 are used to clamp different types of parts to achieve the purpose of multiple processes and quick change of product types.

[0062] Optionally, the cushion block 4 is provided with mounting grooves 401 on both sides facing the rectangular base 1 and the vertical plate 2, the mounting grooves 401 are provided with threaded holes, and a through hole is provided on the T-block 404. The T-block 404 is fixed to the cushion block 4 by passing a nut through the through hole on the T-block 404 and the threaded hole on the mounting groove 401.

[0063] Specifically, mounting grooves 401 are provided on two adjacent sides of the cushion block 4, and nuts are passed through the through holes on the T-block 404 and the threaded holes on the mounting grooves 401 in sequence to fix the T-block 404 and the cushion block 4 together, providing structural support for the cushion block 4 to slide in the first T-slot 101 and the second T-slot 201.

[0064] Optionally, according to the installation position of the cushion block 4, a hole adjacent to the cushion block 4 is selected on the support plate to install the OK clip accordingly.

[0065] Specifically, a row of threaded holes is provided in the groove 301 on the support plate, and OK clamps can be installed on the threaded holes to provide horizontal clamping force for the parts together with the cushion block 4. Therefore, the OK clamps and the cushion block 4 should be arranged on the same horizontal line.

[0066] like Figure 2a-2b As shown, Figure 2a The structure of the pad 4 is shown. Figure 2bThe structure of the T-block 404 is shown, and the front, back, left and right are determined by the illustrated orientation, that is, the left side and bottom surface of the cushion block 4 are provided with installation grooves, each installation groove is provided with an M6 threaded hole, and the T-block 404 is provided with a through hole, and the T-block 404 is fixed to the installation groove by a hexagonal nut; the top surface of the cushion block 4 is provided with a step structure, the higher table surface is the first step surface 402, and the lower table surface is the second step surface 403, the second step surface 403 supports the part, and the first step surface 402 is aligned and serves as a side plate to block the movement of the part; when the processing procedures of the parts are different, or the processing types of the parts are different, the size of the step structure of the cushion block 4 is also different.

[0067] Optionally, the positioning rod 5 includes a rod shaft 501 and a fixed block 502, and the fixed block 502 is assembled on both sides of the rod shaft 501, wherein: an axial hole is set at one end of the rod shaft 501; and a first through hole is set on two opposite surfaces of the upper end of the fixed block 502, and the first through hole is aligned with the axial hole on the rod shaft 501.

[0068] Specifically, the positioning rod 5 is composed of a rod shaft 501 and a fixed block 502. The two fixed blocks 502 are respectively located on both sides of the rod shaft 501. The first through holes on the two fixed blocks 502 are concentrically arranged with the axial holes of the rod shaft 501 to facilitate the rotation of the rod shaft 501 around the fixed blocks 502; the rod shaft 501 extends out of the side of the vertical plate 2 with the second T-slot 201 to provide positioning services for the parts that need to be clamped.

[0069] Optionally, second through holes are provided on the other two opposite surfaces at the lower end of the fixing block 502 , and the through hole directions of the first through holes and the second through holes located on different horizontal planes are perpendicular, and the positioning rod 5 is fixed on the vertical plate 2 through the second through holes.

[0070] Specifically, the second through hole at the lower end of the fixing block 502 fixes the rod shaft 501 on the vertical plate 2. Under the action of the positioning groove 202 at the top of the vertical plate 2, the rotation degree of the rod shaft 501 around the fixing block 502 can be limited, so that when the rod shaft 501 falls into the positioning groove 202, it plays a positioning role. When replacing parts, the rod shaft 501 can be lifted upward around the fixing block 502, which provides convenience for removing parts.

[0071] like Figure 4a As shown, a second T-slot 201 is provided on one side of the vertical plate 2. Since in this embodiment, one second T-slot 201 clamps two parts, two positioning slots 202 are provided on the top of the vertical plate 2, and the spacing between the two positioning slots 202 is set according to the size of a part, wherein the slot direction of the second T-slot 201 is perpendicular to the slot direction of the positioning slot 202, but are not on the same plane.

[0072] In the above embodiment, two second T-shaped grooves 201 may also be provided on the vertical plate 2, such as Figure 4bAs shown, a second T-slot 201 is provided at the corresponding position on two opposite wide planes of the vertical plate 2. When there are 4, 6, 8, or even a larger even number of first T-slots 101 provided on the rectangular base 1, the vertical plate 2 shown in the figure is applied to the above rectangular base 1, and is located in the middle of the rectangular base 1, and is separated from the support plate 3 by the first T-slot 101, and the vertical plates 2 with a second T-slot 201 are still installed on both sides of the rectangular base 1.

[0073] exist Figure 4b In the vertical plate 2 shown, the shape setting of the positioning rod 5 has also changed slightly. The positioning rod 5 is composed of a rod shaft 501 and a fixed block 502. Two axial holes are set in the middle of the rod shaft 501. The distance between the two axial holes is exactly the length of the positioning groove 202. One side of the vertical plate 2 is installed on the vertical plate 2 by two fixed blocks 502, and the other side of the vertical plate 2 is installed by another two fixed blocks 502. The other axial hole of the rod shaft 501 is installed on the other side of the vertical plate 2.

[0074] Optionally, a mounting base 6 is mounted on the lower surface of the rectangular base 1 .

[0075] Specifically, the mounting base 6 and the rectangular base 1 are installed by rivets, which meets the needs of quick-change tooling. Quick-change can be used to complete the assembly and disassembly of parts outside the machine tool, reducing the waiting time of the machine tool.

[0076] Optionally, the number of the first T-slots 101 provided on the rectangular base 1 includes at least two, and the number of the first T-slots 101 is an even number.

[0077] Specifically, at least two mutually parallel first T-slots 101, each of which can be used to install and place at least two parts, enable the tooling to provide multiple workstations for multiple parts in the transverse and longitudinal directions.

[0078] like Figure 5a As shown, two first T-shaped slots 101 parallel to each other are arranged on the rectangular base 1 , and the first T-shaped slots 101 are parallel to the edge line of the rectangular base 1 .

[0079] In the above embodiment, four first T-shaped slots 101 (such as Figure 5bAs shown), vertical plates 2 with second T-slots 201 are installed on both sides of the rectangular base 1, and the first and second first T-slots 101 are arranged in sequence. Between the third and fourth first T-slots 101, vertical plates 2 with second T-slots 201 on both sides are installed, that is, the second and third first T-slots 101 share a vertical plate 2, a supporting plate 3 is arranged between the first and second first T-slots 101, and a supporting plate 3 is also arranged between the third and fourth first T-slots 101. At the same time, four rows of first T-slots 101 are arranged, and more parts can be clamped at the same time.

[0080] It should be noted that the number of the first T-slots 101 provided on the rectangular base 1 is an even number, and the specific number is not specifically limited and can be designed according to actual needs.

[0081] In such Figure 6 In the embodiment shown, a through hole is provided on the mounting base 6, and the mounting base 6 is connected to the threaded hole below the rectangular base 1 through a specific rivet. The installation of the tooling on the machine tool through the installation base 6 is convenient and quick.

[0082] In one embodiment of the present application, Figure 7 As shown, when the part is placed frontally, that is, when a form of the cavity of the part is being processed, two pads 4 support the part, the stepped structures of the two pads 4 are aligned with the side of the part, and at the same time, the positioning rod 5 is aligned with the other side of the part, and the part is clamped by an OK clamp, and the cavities of multiple parts are processed simultaneously on the machine tool.

[0083] like Figure 8 As shown, when the plane at the bottom of the part needs to be processed, the part needs to be inverted. At this time, the corresponding pad 4 needs to be replaced, and the height difference of the step structure of the pad 4 is increased. At this time, only one of the two pads 4 supports the protrusion of the part, but the step structures of the two pads 4 are aligned with the part, and the positioning rod 5 is aligned with the other side of the part. The part is clamped by the OK clamp, and the planes of multiple parts are processed on the machine tool at the same time.

[0084] like Fig. 9 As shown, the tooling can clamp parts of the same type. If the cavities of the parts are different, only the corresponding pad 4 needs to be replaced to complete the processing of the cavity of another form. That is, the tooling can clamp parts of various forms and complete the milling surface process, milling cavity process, etc. This not only greatly saves the tooling cost and improves the efficiency of the tooling, but also reduces the part changeover time and further improves the utilization rate of the machine tool.

[0085] In summary, the multi-process and multi-station clamping tooling provided by the present application can select different pads 4 when processing different types of parts or performing different processes on the same part, and insert the T-block 404 on the corresponding pad 4 into the first T-slot 101 on the rectangular base 1 and the second T-slot 201 on the vertical plate 2 to ensure the stable placement of the part, align the side of the part to the positioning rod 5 to complete the positioning of the part, and the M8 bidirectional OK clamp can be installed on the support plate 3 to clamp the part. Since there is a row of M8 screws with smaller spacing on the support plate 3 The installation position of the M8 two-way OK clamp can be freely adjusted according to the size of the parts. The tooling can clamp multiple parts at the same time in a single processing, realizing the effect of processing multiple parts, multiple processes and multiple stations with a single tooling, greatly saving the tooling cost and improving the efficiency of tooling. At the same time, there are threaded holes under the rectangular base 1, which cooperate with the mounting base 6 to install rivets to meet the needs of quick-change tooling. When there are more than two sets of tooling, quick change can be used to complete the assembly and disassembly of parts outside the machine tool, reducing the waiting time of the machine tool downtime and further improving the utilization rate of the machine tool.
