Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically to a fitter's workbench. Background Technology

[0002] A fitter's workbench mainly consists of a workbench and a vise. The vise is fixedly mounted on the workbench and is used to clamp the workpiece for machining. Currently, vises are usually fixed to the workbench with bolts. However, some fitter's workbenches require multiple vises. When installing multiple vises, they are first placed in their corresponding positions on the workbench, and then each vise is fixed to the workbench one by one with bolts. This method is not quick and efficient, resulting in low installation efficiency for multiple vises on the workbench. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a fitter's workbench to solve the technical problem in the prior art that the installation efficiency of multiple vises on the workbench is low when multiple vises are installed.

[0004] This utility model is achieved through the following technical solution:

[0005] A fitter's workbench includes a workbench, multiple through holes with non-circular cross-sections disposed on the workbench panel, multiple vises supported on the workbench, multiple vertical rods fixed to the lower ends of the multiple vises and slidably engaged in the multiple through holes, multiple horizontally arranged insertion holes disposed on the multiple vertical rods, multiple insertion rods that cannot move up and down relative to the workbench, and a drive unit for synchronously driving the multiple insertion rods to slide toward the multiple insertion holes and insert into the multiple insertion holes; the insertion rods engage with the insertion holes.

[0006] Furthermore, multiple through holes are evenly spaced along a circumferential path on the panel of the workbench. The centerline of the insertion hole is parallel to the radial direction of the circumferential path. The centerlines of multiple insertion rods coincide with the centerlines of multiple insertion holes one by one. The insertion rods are connected to the workbench in a manner that allows them to slide along their centerlines. The driving unit is used to synchronously drive multiple insertion rods to slide outward along the centerlines of the insertion holes.

[0007] Furthermore, the lower side of the workbench panel has a mounting plate that protrudes downward at the position of each of the insertion rods. Guide holes are formed on multiple mounting plates, and the multiple guide holes are aligned one-to-one with the multiple insertion holes. The insertion rod is slidably engaged in the guide hole on the corresponding mounting plate.

[0008] Furthermore, the driving unit includes a circular plate and multiple circular rods. The circular plate is rotatably connected to the worktable and is coaxially aligned with the circumferential path. The outer circumferential surface of the circular plate is recessed inward to form multiple through slots. The multiple through slots are evenly spaced along the circumferential direction and penetrate the upper and lower sides of the circular plate. The slot walls are arc-shaped. The multiple circular rods are fixed to the inner ends of the multiple insert rods and are all vertically arranged. The circumferential surfaces of the multiple circular rods abut against the arc apex of the arc surface.

[0009] Furthermore, the two ends of the arc surface are connected to the outer circumference of the circular plate with rounded corners.

[0010] Furthermore, the circular plate has a shaft hole in the middle; a shaft is provided in the shaft hole, the shaft is rotatably fitted in the shaft hole, the upper end of the shaft is fixed to the panel of the workbench, and the lower end of the shaft is fixed with a limiting part, the limiting part is used to limit the circular plate so that the circular plate cannot detach downward from the shaft.

[0011] Furthermore, the limiting part includes a limiting plate and a plurality of rolling balls. The limiting plate is fixed to the lower end of the shaft. The edge of the limiting plate protrudes beyond the edge of the lower end face of the shaft. The upper side of the limiting plate is recessed downward to form a plurality of ball sockets. The plurality of rolling balls are located in the plurality of ball sockets in a corresponding manner. The rolling balls cooperate with the ball sockets. A portion of the rolling ball is located on the upper side of the ball socket and abuts against the lower side of the circular plate. The volume of the portion of the rolling ball located on the upper side of the ball socket is smaller than the volume of the portion of the rolling ball located inside the ball socket.

[0012] Furthermore, it also includes a fixing part for fixing the circular plate to the panel of the worktable, so that the circular plate cannot rotate on the panel of the worktable.

[0013] Furthermore, the fixing part includes a protruding plate and a bolt. The protruding plate protrudes outward from the outer periphery of the circular plate, and a screw hole is formed on the protruding plate. The bolt is screwed into the screw hole, and the screw-in end of the bolt is used to abut against the panel of the worktable upward.

[0014] Furthermore, it also includes multiple helical springs, which are fitted one-to-one onto the multiple insert rods. The inner end of each helical spring is fixedly connected to the round rod, and the outer end is fixedly connected to the mounting plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] When multiple vises need to be installed on the workbench, the drive unit can synchronously drive multiple insertion rods to slide one-to-one toward and insert into the multiple insertion holes. After placing the multiple vises of the fitter's workbench of this invention at their corresponding installation positions on the workbench, the multiple vises can be synchronously fixed to the workbench. The installation efficiency is high when installing the multiple vises of the fitter's workbench of this invention on the workbench.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] In the above description of this utility model, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0031] Please see Figure 1-8This utility model provides a technical solution: a fitter's workbench, including a workbench, through holes, vises 1, vertical bars 2, insertion holes 3, insertion rods 4, and a drive unit. Multiple through holes are provided on the workbench panel 5. The cross-section of each through hole is not circular; specifically, the cross-section of each through hole can be square. Multiple vises 1 are supported on the workbench. Multiple vertical bars 2 are fixed to the lower ends of the multiple vises 1 in a one-to-one correspondence. 2. The insertion holes 3 are slidably fitted into multiple through holes in a one-to-one correspondence. There are multiple insertion holes 3, which are correspondingly provided on multiple vertical rods 2. The insertion holes 3 are horizontally arranged. There are multiple insertion rods 4, which cannot move up and down relative to the worktable. The multiple insertion rods 4 are connected to the worktable in a horizontally slidable manner. The insertion rods 4 cooperate with the insertion holes 3. The driving unit is used to synchronously drive the multiple insertion rods 4 to slide towards the multiple insertion holes 3 in a one-to-one correspondence and insert into the multiple insertion holes 3 in a one-to-one correspondence.

[0032] When multiple vises 1 need to be installed on the workbench, first place the multiple vises 1 in their corresponding installation positions on the workbench. Specifically, insert the multiple vertical rods 2 into the multiple through holes one by one, so that the bottoms of the multiple vises 1 are all supported on the panel 5 of the workbench. Then, fix the multiple vises 1 on the workbench. Specifically, drive the multiple insertion rods 4 synchronously to slide towards the multiple insertion holes 3 one by one and insert them into the multiple insertion holes 3.

[0033] After the insertion rod 4 is inserted into the corresponding insertion hole 3, since the insertion rod 4 cannot move up and down relative to the workbench, the vertical rod 2 also cannot move up and down relative to the workbench. Since the cross-section of the through hole is not circular, the vertical rod 2 slides within the through hole. The vertical rod 2 cannot move horizontally within the through hole and cannot rotate within the through hole. At this time, the vertical rod 2 is fixed on the workbench, and the vise 1 can be fixed on the workbench.

[0034] The drive unit can synchronously drive multiple insertion rods 4 to slide one-to-one toward and insert into multiple insertion holes 3. After placing multiple vises 1 in their corresponding installation positions on the workbench of this utility model, the multiple vises 1 can be synchronously fixed on the workbench. The installation efficiency is high when installing the multiple vises 1 on the workbench of this utility model.

[0035] In this embodiment, the workbench includes a panel 5 and multiple support legs 6. The upper ends of the multiple support legs 6 are fixed on the panel 5, and the multiple support legs 6 are used to horizontally support the panel 5.

[0036] In this embodiment, a plurality of through holes are evenly spaced along a circumferential path on the panel of the workbench. The axis of the insertion hole 3 is parallel to the radial direction of the circumferential path. The axis of a plurality of insertion rods 4 corresponds one-to-one with the axis of the plurality of insertion holes 3. The insertion rods 4 are connected to the workbench in a manner that allows them to slide along their axis. The driving unit is used to synchronously drive the plurality of insertion rods 4 to slide outward along the axis of the insertion hole 3. Here, "outward" refers to the direction away from the axis of the circumferential path, and in the following description, "outward" will have this meaning. Conversely, the direction closer to the axis of the circumferential path is "inward," and in the following description, "inward" will have this meaning.

[0037] Since the centerlines of the multiple insertion rods 4 coincide with the centerlines of the multiple insertion holes 3 in a one-to-one correspondence, the insertion rods 4 are connected to the worktable in a manner that allows them to slide along their centerlines. After the drive unit synchronously drives the multiple insertion rods 4 to slide outward a certain distance along the centerlines of the insertion holes 3, the multiple insertion rods 4 can be inserted into the multiple insertion holes 3 in a one-to-one correspondence.

[0038] In this embodiment, the lower side of the panel 5 of the workbench has a mounting plate 7 protruding downwards at the position corresponding to each of the insertion rods 4. Multiple mounting plates 7 have guide holes, each corresponding to one of the insertion holes 3. The insertion rod 4 slides within the guide hole on the corresponding mounting plate 7. With this structure, the insertion rod 4 cannot move up or down relative to the workbench, and can be connected to the workbench in a way that allows it to slide along its axis.

[0039] In this embodiment, the driving unit includes a circular plate 8 and multiple circular rods 9. The circular plate 8 is rotatably connected to the worktable and is coaxially arranged with the circumferential path. The outer circumferential surface of the circular plate 8 is recessed inward to form multiple through grooves 10. The multiple through grooves 10 are evenly spaced along the circumferential direction. The through grooves 10 penetrate the upper and lower sides of the circular plate 8. The groove wall of the through groove 10 is an arc surface 11. The multiple circular rods 9 are fixed to the inner ends of the multiple insertion rods 4 one by one and are all arranged vertically. The circumferential surfaces of the multiple circular rods 9 abut against the arc apex of the arc surface 11 one by one.

[0040] When the circular plate 8 is rotated, the multiple arc surfaces 11 will move synchronously and in a one-to-one correspondence relative to the multiple circular rods 9. That is, the multiple circular rods 9 can move synchronously and in a one-to-one correspondence relative to the multiple arc surfaces 11.

[0041] During the movement of the round rod 9 relative to the corresponding arc surface 11, as the round rod 9 moves from the apex of the arc surface 11 to the end of the arc surface 11, the arc surface 11 can press the corresponding round rod 9 outward, and the round rod 9 can push the corresponding insertion rod 4 outward, causing the insertion rod 4 to slide outward in the corresponding guide hole. After the circular plate 8 rotates a certain angle, the round rod 9 can move out of the through groove 10 and abut against the circumferential surface of the circular plate 8.

[0042] During the synchronous and one-to-one movement of the multiple round rods 9 relative to the multiple arc surfaces 11, the multiple insertion rods 4 can synchronously and one-to-one slide outward within the multiple guide holes. The driving unit can thus synchronously drive the multiple insertion rods 4 to slide outward along the axis of the insertion hole 3. This allows for relatively convenient synchronous driving of the multiple insertion rods 4 to slide outward along the axis of the insertion hole 3, and relatively convenient driving of the multiple insertion rods 4 to slide one-to-one towards and insert into the multiple insertion holes 3.

[0043] In this embodiment, the upper end of the round rod 9 abuts against the lower side of the panel 5 of the workbench, preventing the insertion rod 4 and the round rod 9 from rotating around the axis of the guide hole.

[0044] In this embodiment, the connection points between the two ends of the arc surface 11 and the outer circumferential surface of the circular plate 8 are both rounded at corners 12. That is, the connection points between the two ends of the arc surface 11 and the outer circumferential surface of the circular plate 8 are both smooth. During the rotation of the circular plate 8, the circular rod 9 can be easily moved out of the through groove 10 and abut against the circumferential surface of the circular plate 8.

[0045] In this embodiment, the circular plate 8 has a shaft hole 13 in its center; a shaft 14 is provided in the shaft hole 13, and the shaft 14 is rotatably fitted into the shaft hole 13. The upper end of the shaft 14 is fixed to the panel 5 of the worktable, and the lower end of the shaft 14 is fixed with a limiting part. The limiting part is used to limit the circular plate 8 so that the circular plate 8 cannot detach downward from the shaft 14. The circular plate 8 can thus be rotatably connected to the worktable.

[0046] In this embodiment, the limiting part includes a limiting plate 15 and a plurality of rolling balls 16. The limiting plate 15 is fixed to the lower end of the shaft 14. The edge of the limiting plate 15 protrudes from the edge of the lower end face of the shaft 14. The upper side of the limiting plate 15 is recessed downward to form a plurality of ball sockets. The plurality of rolling balls 16 are located in the plurality of ball sockets in a corresponding manner. The rolling balls 16 cooperate with the ball sockets. A portion of the rolling ball 16 is located on the upper side of the ball socket and abuts against the lower side of the circular plate 8. The volume of the portion of the rolling ball 16 located on the upper side of the ball socket is smaller than the volume of the portion of the rolling ball 16 located in the ball socket.

[0047] Since a portion of the ball 16 is located on the upper side of the ball socket and abuts against the lower side of the circular plate 8, the circular plate 8 cannot move downward on the shaft 14. The limiting part can thus limit the circular plate 8 so that the circular plate 8 cannot detach downward from the shaft 14.

[0048] During the rotation of the circular plate 8, the ball can roll in the ball socket under the action of friction of the circular plate 8. The friction between the circular plate 8 and the limiting part is rolling friction, which makes the friction force on the circular plate 8 relatively small.

[0049] Because the rolling ball 16 mates with the socket, the volume of the portion of the rolling ball 16 located on the upper side of the socket is smaller than the volume of the portion of the rolling ball 16 located inside the socket. This prevents the rolling ball 16 from detaching upwards from the socket, thereby improving the structural stability of the fitter's workbench described in this invention.

[0050] In this embodiment, the fitter's workbench of the present invention further includes a fixing part, which is used to fix the round plate 8 to the panel 5 of the workbench so that the round plate 8 cannot rotate on the panel 5 of the workbench.

[0051] After the circular plate 8 rotates at a certain angle and the circular rod 9 moves out of the through groove 10 and abuts against the circumferential surface of the circular plate 8, the circular plate 8 is fixed to the panel 5 of the workbench by the fixing part, so that the circular plate 8 cannot rotate on the panel 5 of the workbench. At this time, the circumferential surface of the circular plate 8 can hold against the circular rod 9, so that the circular rod 9 and the insertion rod 4 cannot slide inward, and the outer end of the insertion rod 4 can be more stably held in the insertion hole 3.

[0052] In this embodiment, the fixing part includes a protruding plate 17 and a bolt 18. The protruding plate 17 protrudes outward from the outer periphery of the circular plate 8. A screw hole is formed on the protruding plate 17. The bolt 18 is screwed into the screw hole. The screw-in end of the bolt 18 is used to abut against the panel 5 of the workbench upward.

[0053] Rotating the bolt 18 within the screw hole causes it to move upwards. After the bolt 18 moves upwards a certain distance, the screw-in end of the bolt 18 abuts against and presses against the panel 5 of the workbench. Under the frictional force between the screw-in end of the bolt 18 and the panel 5 of the workbench, the circular plate 8 can be relatively fixed to the panel 5 of the workbench. The fixing part can thus fix the circular plate 8 to the panel 5 of the workbench, preventing the circular plate 8 from rotating on the panel 5 of the workbench.

[0054] Rotate the bolt 18 in the screw hole to move the bolt 18 downward. After the bolt 18 moves downward a certain distance, the screw-in end of the bolt 18 moves to the bottom of the panel 5 of the workbench. At this time, the fixing part can be released from fixing the circular plate 8, and the circular plate 8 can continue to rotate on the panel 5 of the workbench.

[0055] In this embodiment, the fitter's workbench of the present invention further includes multiple helical springs 19, which are correspondingly sleeved on multiple insert rods 4. The inner end of each helical spring 19 is fixedly connected to the round rod 9, and the outer end is fixedly connected to the mounting plate 7.

[0056] As the multiple round rods 9 move outward, they compress the multiple helical springs 19 in a one-to-one correspondence.

[0057] When it is necessary to remove the vise 1 from the workbench, release the fixing part from the circular plate 8, and then rotate the circular plate 8. During the rotation of the circular plate 8, the multiple arc surfaces 11 can move synchronously and one-to-one relative to the multiple circular rods 9, that is, the multiple circular rods 9 can move synchronously and one-to-one relative to the multiple arc surfaces 11.

[0058] After the circular plate 8 rotates at a certain angle, multiple circular rods 9 can enter multiple through slots 10 synchronously and one by one. During the continued rotation of the circular plate 8, the circular rods 9 can move relative to the corresponding arc surface 11 within the corresponding through slot 10 from the end of the arc surface 11 to the top of the arc surface 11.

[0059] As the round rod 9 moves from the end of the arc surface 11 to the apex of the arc surface 11 within the corresponding through groove 10, the multiple helical springs 19 can elastically reset. These multiple helical springs 19 synchronously and one-to-one push the multiple round rods 9 inward, and the multiple round rods 9 synchronously and one-to-one pull the multiple insertion rods 4 inward. The multiple insertion rods 4 synchronously and one-to-one are then pulled out from the multiple insertion holes 3. After the multiple insertion rods 4 are synchronously and one-to-one pulled out from the multiple insertion holes 3, the vise 1 is moved upward. The vise 1 drives the vertical rod 2 to pull upward from the corresponding through hole, thus removing the vise 1 from the workbench. This method is convenient for removing multiple vises 1 from the workbench of this utility model.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
