Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the invention and therefore show only the structures which are relevant to the invention.
In a first embodiment, as shown in fig. 1 to 8, the present invention provides a quick positioning fixture, including: a mounting base 2 and a positioning connector 3. The mounting seat 2 is suitable for being provided with a plurality of positioning connecting pieces 3. The positioning connection 3 is adapted to position a workpiece placed on the mount 2. The above components are described in detail below.
The mounting seat 2 is suitable for placing a workpiece, and after the workpiece is placed, the relative position of the workpiece and the mounting seat 2 is adjusted so as to process the workpiece. Furthermore, the mounting base 2 is adapted to mount a number of positioning connectors 3.
The positioning connecting pieces 3 are arranged, the positioning connecting pieces 3 are provided with a plurality of positioning connecting pieces, and after the workpiece is placed on the mounting seat 2, the workpiece can be positioned on the mounting seat 2 through one or more positioning connecting pieces 3, so that the tool is convenient for machining the workpiece. Specifically, a plurality of sliding grooves 21 are formed in the upper surface of the mounting seat 2 at equal intervals along the length direction, and the positioning connecting piece 3 is slidably arranged in the sliding grooves 21. One positioning connection 3 corresponds to one chute 21. The positioning connector 3 can slide along the chute 21 to adjust the relative position of the positioning connector 3 and the tool, i.e. the relative position of the workpiece and the tool. By providing a plurality of positioning connectors 3, the work can be positioned in combination.
In order to achieve the above effect, the positioning connector 3 includes a connecting seat 32, and the connecting seat 32 is adapted to the sliding slot 21, so that the connecting seat 32 can slide along the sliding slot 21. Meanwhile, guide blocks 321 are arranged on two sides of the connecting seat 32, guide grooves 211 are formed in two sides of the sliding groove 21 along the length direction, the guide blocks 321 correspond to the guide grooves 211, namely, the sliding groove 21 is connected with the guide grooves 211 to form T-shaped grooves, the connecting seat 32 is connected with the guide blocks 321 to form T-shaped blocks, and the effect of positioning the connecting seat 32 in the sliding groove 21 can be achieved through the matching of the two forming and the size, so that the connecting seat 32 can only slide along the length direction of the sliding groove 21.
The positioning connector 3 is suitable for stretching along the vertical direction, and the top of the positioning connector 3 is suitable for opening and closing along the length direction. The inner side of the positioning connecting piece 3 is provided with a floating positioning piece 4 and a floating resetting piece 5 in a split mode, and the floating resetting piece 5 is arranged below the floating positioning piece 4. The floating retainer 4 is adapted to be lifted in a vertical direction, and the floating retainer 4 is adapted to be connected to a workpiece. The floating reset member 5 is also adapted to be lifted in the vertical direction, and the floating reset member 5 corresponds to the floating positioning member 4. Through the arrangement, when the positioning connecting piece 3 contracts vertically once, the two sides of the top of the positioning connecting piece 3 descend vertically to be abutted with the floating positioning piece 4, the floating positioning piece 4 pushes the two sides of the top of the positioning connecting piece 3 to open along the length direction until the floating positioning piece 4 protrudes out of the positioning connecting piece 3, and the two sides of the top of the positioning connecting piece 3 are combined to connect workpieces; when the positioning connecting piece 3 stretches along the vertical direction once, the positioning connecting piece 3 pushes the floating positioning piece 4 to rise so that the floating positioning piece 4 is far away from the floating reset piece 5; when the positioning connecting piece 3 is contracted vertically for the second time, the two sides of the top of the positioning connecting piece 3 are lowered vertically to be in contact with the floating reset piece 5, the floating reset piece 5 pushes the two sides of the top of the positioning connecting piece 3 to be opened in the length direction until the floating reset piece 5 protrudes out of the positioning connecting piece 3, and the two sides of the top of the positioning connecting piece 3 are combined; when the positioning connecting piece 3 stretches along the vertical direction for the second time, the positioning connecting piece 3 pushes the floating reset piece 5 to rise, the floating reset piece 5 is abutted with the floating positioning piece 4, so that the bottom of the floating reset piece 5 pushes the two sides of the top of the positioning connecting piece 3 to open along the length direction, and the floating positioning plate 41 and the floating reset plate 51 drop to reset.
In the above-mentioned process of installing and positioning the workpiece, compared with the positioning method in the prior art, when adjusting the parts such as the slide block for positioning the workpiece, the operator needs to unscrew the bolt between the slide block and the mounting seat 2, then adjust the position between the slide block and the mounting seat 2, and then tighten the bolt. The whole process is troublesome to operate. Therefore, in this embodiment, the trouble of frequently disassembling and assembling the bolts is avoided by providing the positioning connector 3 and the floating positioning member 4 and the floating resetting member 5 in the positioning connector 3, and at the same time, the positioning is also more accurate.
In order to achieve the above effect, the positioning connector 3 further includes two telescopic members 33 which are mirror images of each other and are disposed on the connector base 32. One end of the expansion piece 33 is connected with the connecting seat 32, and the other ends of the expansion pieces 33 are mutually abutted. One end of the expansion piece 33, which faces the connecting seat 32, is adapted to expand and contract in the vertical direction, and the other end is adapted to expand and contract in the length direction.
The structure of the telescopic member 33 is specifically described below, and the telescopic member 33 includes a vertical plate 331 and a horizontal plate 332. The vertical plate 331 is vertically arranged, and one end of the vertical plate 331 is fixedly connected with the connecting seat 32. One end of the horizontal plate 332 is slidably connected with one end of the vertical plate 331 away from the connecting seat 32, and one end of the horizontal plate 332 away from the vertical plate 331 is suitable for extending and retracting along the length direction. A plurality of vertical springs 3311 are arranged in the vertical plate 331, one end of each vertical spring 3311 is connected with the horizontal plate 332, and the other end is connected with the vertical plate 331. With the above arrangement, when the operator pushes the horizontal plate 332 from above in the vertical direction, the horizontal plate 332 can slide downward in the length direction of the vertical plate 331, and the vertical spring 3311 is pressed in the process of vertically lowering the horizontal plate 332, so that the elastic force of the vertical spring 3311 is gradually increased. Conversely, when the operator releases the horizontal plate 332, the vertical spring 3311 can push the horizontal plate 332 to slide upward along the length direction of the vertical plate 331. An opening and closing plate 3321 and a horizontal spring 3322 are arranged in the horizontal plate 332, and the opening and closing plate 3321 is slidably arranged in the horizontal plate 332. One end of the horizontal spring 3322 is connected to the horizontal plate 332, and the other end is connected to the opening/closing plate 3321. With the above arrangement, when the opening and closing plate 3321 receives pressure in the horizontal direction, the opening and closing plate 3321 can be retracted into the horizontal plate 332 in the longitudinal direction, and at the same time, the opening and closing plate 3321 presses the horizontal spring 3322 so that the elastic force of the horizontal spring 3322 is gradually increased. On the contrary, when the horizontal force applied to the opening and closing plate 3321 is eliminated, the horizontal spring 3322 pushes the opening and closing plate 3321 to extend out of the horizontal plate 332, and it should be noted that, due to the arrangement of the horizontal spring 3322, the opening and closing plate 3321 will retract into the horizontal plate 332 under the condition of being pressed, so that the opening and closing plate 3321 is in a state of extending out of the horizontal plate 332, and in this case, the opening and closing plates 3321 on both sides are abutted against each other, thereby presenting a state of closing the positioning connector 3. The reason that the two opening and closing plates are in contact with each other in normal state is that the opening and closing plates can be closed when the workpiece is processed
The floating positioning member 4 and the floating reset member 5 are disposed between the two vertical plates 331, and the floating positioning member 4 and the floating reset member 5 are located below the opening and closing plate 3321 in an initial state. The upper surface both ends of the floating locating piece 4 are inclined planes, the upper surface both ends of the floating reset piece 5 are inclined planes, and the lower surface of the upper surface of the floating reset piece 5 is an inclined plane. Meanwhile, the upper surface and the lower surface of the end of the opening/closing plate 3321 far from the horizontal plate 332 are inclined surfaces. With the above arrangement, when the operator presses the horizontal plate 332 once, the opening and closing plate 3321 is lowered to abut against the top of the floating retainer 4, the floating retainer 4 is retracted toward the horizontal plate 332 by pushing the opening and closing plate 3321 in cooperation with the inclined surface of the opening and closing plate 3321 until the distance between the two opening and closing plates 3321 is equal to the length of the floating retainer 4, the horizontal plate 332 is continued to be lowered until the opening and closing plate 3321 is disconnected from the floating retainer 4, at this time, the opening and closing plate 3321 is located between the floating retainer 4 and the floating retainer 5, and the horizontal spring 3322 pushes the opening and closing plate 3321 out of the horizontal plate 332 so that the floating retainer 4 protrudes out of the horizontal plate 332. Then, the horizontal plate 332 is released, the vertical spring 3311 pushes the horizontal plate 332 to rise, and the opening and closing plate 3321 holds the floating retainer 4 from below and pushes the floating retainer 4 to rise. When the operator presses the horizontal plate 332 for the second time, the opening and closing plate 3321 descends to be in contact with the top of the floating reset piece 5, the floating reset piece 5 pushes the opening and closing plate 3321 to retract inwards to the horizontal plate 332 by being matched with the inclined surface of the opening and closing plate 3321 until the distance between the two opening and closing plates 3321 is equal to the length of the floating reset piece 5, the horizontal plate 332 continues to descend until the opening and closing plate 3321 is disconnected with the floating reset piece 5, and the horizontal spring 3322 pushes the opening and closing plate 3321 to extend out of the horizontal plate 332, and at the moment, the opening and closing plate 3321 is positioned below the floating reset piece 5. Then, the horizontal plate 332 is released, the vertical spring 3311 positions the horizontal plate 332 to rise, the opening and closing plate 3321 supports the floating reset piece 5 from below and pushes the floating reset piece 5 to rise, when the floating reset piece 5 rises to be in contact with the floating positioning piece 4, the floating reset piece 5 and the floating positioning piece 4 reach the maximum stroke, at this time, along with the vertical spring 3311 continuously pushing the horizontal plate 332 to rise, the floating reset piece 5 is matched with the inclined surface of the upper surface of the opening and closing plate 3321 through the inclined surface of the lower surface, and the pushing opening and closing plate 3321 is retracted into the horizontal plate 332. When the distance between the two opening and closing plates 3321 is equal to the length of the floating reset piece 5, the floating reset piece 5 and the floating positioning piece 4 drop to reset under the action of gravity.
The structure of the floating retainer 4 is specifically described below, and the floating retainer 4 includes a retainer plate 41 and a support column 42 provided on one side of the retainer plate 41. The two ends of the positioning plate 41 are inclined and correspond to the opening/closing plate 3321. The support column 42 is disposed towards the floating reset member 5, and the support column 42 abuts against the inner wall of the connection seat 32. Lifting grooves 31 are respectively formed in the two inner side walls of the connecting seat 32, and two sides of the positioning plate 41 are respectively arranged in the lifting grooves 31 in a sliding manner. When the opening and closing plate 3321 abuts against the top of the positioning plate 41 along the vertical direction, the positioning plate 41 pushes the opening and closing plate 3321 to open the top of the connecting seat 32 until the positioning plate 41 is separated from the opening and closing plate 3321. When the opening and closing plate 3321 abuts against the bottom of the positioning plate 41 along the vertical direction, the opening and closing plate 3321 pushes the positioning plate 41 to slide upwards along the lifting groove 31.
The positioning plate 41 is adapted to be connected with a workpiece, and in order to achieve this effect, the end face of the positioning plate 41 is provided with a plurality of positioning holes 411, and the workpiece is adapted to be connected with the positioning plate 41 through the positioning holes 411.
The structure of the floating reset member 5 will be specifically described, the floating reset member 5 includes a reset plate 51, the reset plate 51 is disposed below the positioning plate 41, and two sides of the reset plate 51 are slidably disposed in the lifting groove 31, respectively. Here, the positioning plate 41 abuts against the connection seat 32 through the support column 42 to limit the initial position of the positioning plate 41, and the reset plate 51 is located at the bottom of the lifting slot 31 under the action of gravity, so in the initial state, the positioning plate 41 and the reset plate 51 are not in an abutting arrangement due to different limiting modes, and a certain gap is formed between the positioning plate 41 and the reset plate 51, that is, when the horizontal plate 332 is pressed once, the opening and closing plate 3321 can be inserted into the gap between the positioning plate 41 and the reset plate 51. The upper surface of the reset plate 51 corresponds to the lower surface of the positioning plate 41, so that when the opening/closing plate 3321 pushes the reset plate 51 to rise, the reset plate 51 can be completely overlapped with the positioning plate 41, and the situation that only the reset plate 51 is reset and the positioning plate 41 is not reset is avoided. Inclined surfaces are mirror-image-mounted on both sides of the lower surface of the reset plate 51, so that the opening and closing plate 3321 can be pushed correctly to retract into the horizontal plate 332 when the reset plate 51 abuts against the positioning plate 41. With the above arrangement, when the opening and closing plate 3321 abuts against the top of the reset plate 51 along the vertical direction, the reset plate 51 pushes the opening and closing plate 3321 to open until the reset plate 51 is separated from the opening and closing plate 3321. When the opening and closing plate 3321 abuts against the bottom of the reset plate 51 along the vertical direction, the opening and closing plate 3321 pushes the reset plate 51 to slide upwards along the lifting groove 31, the reset plate 51 slides to abut against the positioning plate 41 along the vertical direction, and the reset plate 51 pushes the opening and closing plate 3321 to open, so that the reset plate 51 and the positioning plate 41 drop to reset in sequence.
In order to ensure that the relative positions of the reset plate 51 and the positioning plate 41 are consistent, the end surface of the reset plate 51 is provided with a matching hole 511, and the support column 42 is sleeved in the matching hole 511.
In order to further clean the positioning hole 411, so as to prevent chips generated during processing of the workpiece from falling into the positioning hole 411 to block the positioning hole 411, a plurality of cleaning columns 512 are further disposed on the upper surface of the reset plate 51, and one cleaning column 512 corresponds to one positioning hole 411. When the reset plate 51 abuts against the positioning plate 41, the cleaning column 512 is inserted into the positioning hole 411 to clean impurities in the positioning hole 411.
An embodiment two, this embodiment is implemented on the basis of the embodiment one, and this embodiment provides an automatic machine tool, including a quick positioning jig as described in embodiment two, its specific structure is the same as that of embodiment one, and detailed description is omitted here, and a specific automatic machine tool includes: the machine tool body 1, the machine tool body 1 is a high-performance, high-precision, low-noise feed type automatic machine tool, and is an automatic machine tool in which a machining program is controlled by a cam. Specifically, the workpiece is placed in the machine tool body 1, and after positioning is completed, the machine tool body 1 can cold work the workpiece so that the workpiece can be shaped and stored as desired.
