Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a jaw plate and a processing fixture. Background Technology

[0002] Flat-jaw vises are widely used clamping tools in machining. They clamp workpieces by using fixed jaws and jaw plates on movable jaws. When the thickness of the workpiece (vertical dimension) is less than the depth of the clamping groove between the two jaw plates, it is usually necessary to place a shim in the groove to raise the workpiece height, so that the surface of the workpiece to be machined protrudes from the top surface of the jaw plates, thereby facilitating tool machining.

[0003] However, existing technology has significant drawbacks: in actual processing, because workpieces of different sizes need to be clamped frequently, operators must repeatedly remove and replace pads of different thicknesses. Since pads often lack standardized storage and management, it is frequently discovered that the required pad is missing only when needed, forcing operators to spend considerable time searching for suitable pads, severely impacting production efficiency.

[0004] Furthermore, improper selection of the shim block can lead to a series of problems: if the shim block is too thick, the clamping area of ​​the workpiece will be too small, resulting in unstable clamping; if the shim block is too thin, the surface of the workpiece to be machined will be too close to the top surface of the jaws, greatly increasing the risk of the cutting tool hitting and being damaged by the jaws. These problems make existing flat-jaw vises inefficient and pose safety hazards when machining workpieces of various sizes. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a jaw plate and processing fixture to solve the problem in the prior art that the pads are lost due to repeated removal and replacement of pads of different thicknesses, and a lot of time is spent searching for suitable pads, which seriously affects production efficiency.

[0006] This utility model is achieved through the following technical solution:

[0007] A jaw plate includes a plate body and a plurality of pads. The clamping surface of the plate body is provided with a groove for receiving the plurality of pads. The plurality of pads are embedded in the groove and are evenly arranged in the vertical direction.

[0008] The pad extends along the length of the plate. Both ends of the pad are slidably connected to the end walls of the groove along the width of the plate with a single degree of freedom. When the side of the pad facing the plate abuts against the plane of the groove facing away from the opening, the side of the pad facing away from the plate is coplanar with the clamping surface of the plate.

[0009] Furthermore, a first notch is provided in the middle of the side of the pad facing the plate, and a pusher is provided in the cavity between the first notch on the multiple pads and the plane of the groove facing away from the opening;

[0010] One end of the push bar is slidably connected to the plate in the vertical direction, and the other end extends along the width direction of the plate. The dimension of the first notch along the width direction of the plate is smaller than the length dimension of the push bar.

[0011] An adjustment part is provided between the pusher and the plate to drive the pusher to slide on the plate.

[0012] Furthermore, the vertical dimension of the push bar is smaller than the vertical dimension of the pad bar.

[0013] Furthermore, a circular hole is provided at one end of the top surface of the push bar, and a circular rod is provided inside the circular hole. The inner circular surface of the circular hole is in contact with the outer circular surface of the circular rod and is movably connected.

[0014] The bottom end of the round rod is detachably fixed to the bottom surface of the groove.

[0015] Furthermore, a through hole coaxial with the round rod is provided on the top wall of the groove, and the adjusting part includes a sleeve sleeved outside the round rod. The bottom end of the sleeve is fixedly connected to the push bar, and the top end extends out of the plate body through the through hole. The vertical dimension of the groove is smaller than the length dimension of the sleeve.

[0016] Furthermore, the sleeve is composed of multiple tubes that are sleeved on the outside of the round rod, with two adjacent tubes hinged at their opposite ends, and the rotation center line is perpendicular to the axis of the round rod.

[0017] The lowest tube is hinged to the push bar, and its rotation center line is parallel to the rotation center line of any two tubes that are hinged together.

[0018] Two adjacent pads face each other and their two planes are in contact. The center distance between the rotation center lines at both ends of the tube is equal to the dimension of the pad in the vertical direction.

[0019] Furthermore, a second notch is provided on the top surface of the plate. One side of the second notch is connected to a through hole, and the other side extends through the plate along the width direction towards the side opposite to the clamping surface.

[0020] The diameter of the tube is less than or equal to the dimension of the second notch along the length of the plate.

[0021] Furthermore, two protrusions are symmetrically arranged at both ends of the pad strip, and a limiting frame is commonly fitted around the multiple pad strips. The limiting frame is detachably fixed to the plate body, and the side of the limiting frame facing away from the plate body is coplanar with the clamping surface of the plate body.

[0022] The inner walls at both ends of the limiting frame are provided with multiple third notches that correspond one-to-one with multiple pads. The two protrusions at both ends of the pads are respectively embedded in the two corresponding third notches, and the protrusions and the corresponding third notches slide in a single degree of freedom along the width direction of the plate.

[0023] Furthermore, a stop block is fixedly connected to the side of the protrusion facing the plate, and the outer dimensions of the third notch are smaller than those of the stop block.

[0024] A machining fixture includes the aforementioned jaw plates and a flat-jaw vise body. Two jaw plates are provided, and the two jaw plates are detachably and fixedly connected to a fixed jaw and a movable jaw in the flat-jaw vise body, respectively. The two grooves are located on two opposite planes of the two plates.

[0025] The beneficial effects of this utility model are as follows:

[0026] This jaw plate and machining fixture, by embedding pads into grooves and sliding them along the width of the plate, allows the pads to slidably protrude outside the grooves, meaning the pads partially protrude beyond the clamping surface of the plate. This allows them to replace pad blocks for supporting and lifting workpieces. Simultaneously, when multiple pads are evenly arranged vertically and fully embedded in the grooves, the pads can act as clamping parts of the plate to hold the workpiece. A pad at a corresponding height can be slid out according to the workpiece size to adjust the height of the support point, raising the workpiece to a suitable height. This eliminates the need to repeatedly remove and replace pads of different thicknesses and avoids spending considerable time searching for suitable pads, thus improving production efficiency.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] Please see Figure 1-12 The present invention provides a technical solution: a jaw plate, comprising a plate body 1 and a plurality of pads 2, wherein the clamping surface of the plate body 1 is provided with a groove 11 for accommodating the plurality of pads 2, and the plurality of pads 2 are embedded in the groove 11 and are evenly arranged in the vertical direction;

[0047] The pad strip 2 extends along the length of the plate 1. Both ends of the pad strip 2 are slidably connected to the end walls of the groove 11 along the width of the plate 1 with a single degree of freedom. When the side of the pad strip 2 facing the plate 1 abuts against the plane of the groove 11 facing away from the opening, the side of the pad strip 2 facing away from the plate 1 is coplanar with the clamping surface of the plate 1.

[0048] In this solution, by embedding the pad strip 2 into the groove 11 and sliding it along the width direction of the plate 1, the pad strip 2 can slide out of the groove 11, that is, the pad strip 2 partially protrudes outside the clamping surface of the plate 1, and can replace the pad block to support and lift the workpiece. Figure 1 As shown; at the same time, when multiple pads 2 are evenly arranged in the vertical direction and the multiple pads 2 are completely embedded in the groove 11, the pads 2 can serve as the clamping part of the plate 1 to clamp the workpiece. According to the workpiece size, a pad 2 of the corresponding height can be slid out to adjust the height of the support point and lift the workpiece to a suitable height. There is no need to repeatedly remove and replace pads of different thicknesses, and spend a lot of time finding suitable pads, thus improving production efficiency.

[0049] Among them, sliding grooves along the width direction of plate 1 can be opened on the end walls at both ends of the groove 11. By inserting the two ends of the pad 2 into the two sliding grooves on the end walls of the groove 11, and with the top surface of the pad 2 parallel to the top surface of plate 1, the pad 2 can slide in the groove 11 along the width direction of plate 1, so that the pad 2 is partially exposed as a support point for the workpiece, thereby raising the height of the workpiece.

[0050] Alternatively, a hole extending along the width of the plate 1 can be made in the pad strip 2. One end of a lead screw is inserted through the hole into the groove 11, and the lead screw and the pad strip 2 are rotatably engaged. Pins or welded protrusions 22 are inserted into both ends of the lead screw in the pad strip 2 to restrict the axial movement of the lead screw on the pad strip 2. A threaded hole is made in the corresponding position in the groove 11. By inserting one end of the lead screw in the groove 11 into the threaded hole and connecting it through the threaded engagement, the pad strip 2 can be moved along the width of the plate 1 and its position adjusted simply by rotating the lead screw. The operation is simple and convenient.

[0051] Furthermore, the friction between the external thread on the lead screw and the internal thread on the threaded hole can restrict the lead screw from sliding freely along the axial direction, so that the relative position of the pad 2 and the plate 1 remains stable and can stably support and lift the workpiece.

[0052] In this embodiment: A first notch 21 is provided in the middle of the side of the pad 2 facing the plate 1, and a pusher 3 is provided in the cavity between the multiple first notches 21 on the multiple pads 2 and the plane of the groove 11 facing away from the opening;

[0053] One end of the pusher 3 is slidably connected to the plate 1 in the vertical direction, and the other end extends along the width direction of the plate 1. The dimension of the first notch 21 along the width direction of the plate 1 is smaller than the length dimension of the pusher 3.

[0054] An adjustment part is provided between the pusher 3 and the plate 1 to drive the pusher 3 to slide on the plate 1.

[0055] In this design, when the pusher 3 abuts against the pad 2, the pad 2 can be pushed out of the opening of the groove 11. When the pad 2 is not abutting against the pusher 3, the pad 2 can slide freely in the groove 11 along the width direction of the plate 1. Only by applying pressure to the pad 2 into the groove 11 can the pad 2 be reset and completely stored in the groove 11.

[0056] Alternatively, the two edges of the pusher 3 facing the pad 2 in the vertical direction can be beveled. When the adjusting part drives the pusher 3 to slide in the vertical direction, the inclined surface of the pusher 3 facing the direction of movement abuts against the edge of the pad 2 in the direction of movement, applying a component force along the width direction of the plate 1 to the pad 2, causing the pad 2 to slide away from the plate 1 until the end face of the pusher 3 abuts against the pad 2, and the pad 2 slides out to its maximum size, thus achieving the purpose of adjusting the display size of the pad 2.

[0057] Furthermore, the push bar 3 and the pad bar 2 abut against each other to prevent the pad bar 2 from sliding into the groove 11 due to its own weight or being accidentally pressed in, so as to continuously and stably support and lift the workpiece, so as to facilitate the batch processing of workpieces of the same specification and size and improve work efficiency.

[0058] In this embodiment, the vertical dimension of the pusher strip 3 is smaller than the vertical dimension of the pad strip 2.

[0059] In this solution, the pusher 3 can push out one of the pads 2, and at most two pads 2 can be pushed out at the same time, reducing the area of ​​the clamping surface occupied by the pushed-out pads 2 and reducing the impact on the clamped workpiece.

[0060] In this embodiment: a circular hole 31 is provided at one end of the top surface of the push bar 3, and a circular rod 32 is provided in the circular hole 31. The inner circular surface of the circular hole 31 is in contact with the outer circular surface of the circular rod 32 and is movably connected.

[0061] The bottom end of the round rod 32 is detachably and fixedly connected to the bottom surface of the groove 11.

[0062] In this design, the inner circular surface of the circular hole 31 is in contact with the outer circular surface of the circular rod 32, allowing the pusher 3 to slide along the axial direction (vertical direction) of the circular rod 32 and to rotate about the axis of the circular rod 32. The pusher 3 can rotate on the circular rod 32 in the following two states:

[0063] State 1: such as Figure 3 , 4 As shown, push bar 3 is parallel to pad bar 2, push bar 3 does not contact pad bar 2, pad bar 2 can slide normally on round bar 32 along the axis of round bar 32, and push bar 3 can rotate on round bar 32 by adjusting the height position of pad bar 2;

[0064] State 2: such as Figure 5 , 6 As shown, push bar 3 is perpendicular to pad bar 2. Push bar 3 abuts against pad bar 2, pushing pad bar 2 out. Under the obstruction of adjacent pad bar 2, push bar 3 is restricted from sliding along the axial direction of round rod 32, but push bar 3 can still rotate on round rod 32.

[0065] Additionally, the bottom wall of the groove 11 has an insertion hole that connects the inner and outer sides of the groove 11. The outer circular surface of the bottom end of the round rod 32 has an external thread. The bottom end of the round rod 32 is inserted into the insertion hole and connected by threaded engagement. It is then tightened by the thread to achieve the purpose of detaching and removing the round rod 32 for easy installation of the push bar 3.

[0066] In this embodiment: a through hole 12 coaxial with the round rod 32 is provided on the top wall of the groove 11. The adjustment part includes a sleeve 4 sleeved outside the round rod 32. The bottom end of the sleeve 4 is fixedly connected to the push bar 3, and the top end extends out of the plate body 1 through the through hole 12. The vertical dimension of the groove 11 is smaller than the length dimension of the sleeve 4.

[0067] In this design, the inner diameter of the sleeve 4 is equal to the outer diameter of the round rod 32. The sleeve 4 can slide along the axial direction of the round rod 32, and it can also rotate around the axis of the round rod 32. By setting the vertical dimension of the groove 11 to be smaller than the length of the sleeve 4, the top end of the sleeve 4 always extends out of the plate 1 through the through hole 12, which facilitates the control of the sleeve 4 to lift / rotate, and thus the push bar 3 to lift / rotate.

[0068] When in use, if one of the pads 2 needs to be pushed out, hold the sleeve 4 and lift or press the sleeve 4 to the target position. The height of the pusher 3 in the groove 11 can be adjusted by measuring the size of the end of the sleeve 4 that extends out of the plate 1. After the pusher 3 moves to the target height, operate the sleeve 4 to rotate, so that the pusher 3 changes from state one to state two, pushing the corresponding pad 2 out of the groove 11. At the same time, the pusher 3 is embedded in the cavity between the two adjacent pads 2 above and below the target pad 2. The pusher 3 is restricted to move in the vertical direction by the two adjacent pads 2 above and below (when the vertical dimension of the pad 2 is smaller than the vertical dimension of the pad 2, the pusher 3 can move slightly in the vertical direction in the cavity). The pusher 3 always maintains a contact state with the target pad 2.

[0069] In this embodiment: the sleeve 4 is composed of multiple tubes 41 spliced ​​together and sleeved on the outside of the round rod 32. Two adjacent tubes 41 are hinged at opposite ends, and the rotation center line is perpendicular to the axis of the round rod 32.

[0070] The lowest tube 41 is hinged to the push bar 3, and the rotation center line is parallel to the rotation center line of any two tubes 41 that are hinged together.

[0071] Two adjacent pads 2 face each other and their two planes are in contact. The center distance between the rotation center lines at both ends of the tube body 41 is equal to the dimension of the pad 2 in the vertical direction.

[0072] In this design, multiple tubes 41 are hollow structures with openings at both ends, and their inner diameters are equal to the outer diameters of the round rod 32. The top of the round rod 32 can be inserted into multiple tubes 41 in sequence to form an insertion state.

[0073] By arranging multiple tubes 41 evenly along the axial direction of the round rod 32 and hinged two adjacent tubes 41 together, the tubes 41 can rotate around the hinge point after sliding out of the round rod 32. This changes the sleeve 4 outside the plate 1 from a vertical state (round rod 32 inserted into tube 41) to a horizontal state (outer circular surface of sleeve 4 in contact with top surface of plate 1). This reduces the vertical space occupied by sleeve 4, allowing the end of the clamping part (used to clamp the tool holder) on the processing equipment (milling machine, drilling machine, etc.) to be closer to the workpiece on the jaw plate, reducing the impact on tool feed processing.

[0074] In addition, the center distance between the rotation center lines at both ends of the tube body 41 is equal to the dimension of the pad strip 2 in the vertical direction. The height position of the push strip 3 in the groove 11 can be determined by analyzing the number of tube bodies 41 extending out of the plate body 1, which can help adjust the pad strip 2 to the target height.

[0075] In this embodiment: A second notch 13 is provided on the top surface of the plate 1. One side of the second notch 13 is connected to the through hole 12, and the other side extends through the plate 1 along the width direction towards the side opposite to the clamping surface.

[0076] The diameter of the tube 41 is less than or equal to the dimension of the second notch 13 along the length of the plate 1.

[0077] In this design, the tube 41 can be rotated to a horizontal position and embedded in the second notch 13. The two planes along the length of the plate 1 by the second notch 13 restrict the tube 41 from rotating around the axis of the round rod 32.

[0078] In this case, the rotation center line between any two adjacent tubes 41 is perpendicular to the length direction of the push bar 3. When the push bar 3 is in state two, the rotation center lines of the two tubes 41 are parallel to the length direction of the plate 1. After the tubes 41 slide off the round rod 32, they can just rotate and embed into the second notch 13.

[0079] Therefore, in state two, the upper and lower pads 2 of the target pad 2 can restrict the pusher 3 from sliding in the vertical direction. By rotating the tube 41 that slides out of the round rod 32 into the second notch 13, the pusher 3 is restricted from rotating around the axis of the round rod 32, so that the target pad 2 protrudes out of the groove 11, and stably lifts and raises the workpiece, reducing the impact of vibration on the pad 2 on the jaw plate during processing.

[0080] In this embodiment: two protrusions 22 are symmetrically arranged at both ends of the pad strip 2, and a limiting frame 14 is sleeved on the outside of multiple pad strips 2. The limiting frame 14 is detachably fixed to the plate body 1, and the side of the limiting frame 14 facing away from the plate body 1 is coplanar with the clamping surface of the plate body 1.

[0081] The inner walls at both ends of the limiting frame 14 are provided with multiple third notches 141 that correspond one-to-one with multiple pads 2. The two protrusions 22 at both ends of the pads 2 are respectively embedded in the two corresponding third notches 141, and the protrusions 22 and the corresponding third notches 141 slide in a single degree of freedom along the width direction of the plate 1.

[0082] In this design, the limiting frame 14 is fixed to the plate 1 with bolts or similar fasteners, allowing the plate 1 to be detached for easy inspection and replacement of components within the groove 11. When the plate 1 is horizontal, the two protrusions 22 at both ends of the pad 2 are inserted into the two third notches 141 located on the same horizontal plane, making the pad 2 horizontal with its top surface parallel to the horizontal plane, thus supporting and lifting the workpiece. Furthermore, the protrusions 22 slide in the third groove, allowing the pad 2 to move and extend, providing the function of lifting and supporting the workpiece.

[0083] In this embodiment: the protrusion 22 is fixedly connected to the side of the plate 1 with a stop 23, and the outer dimensions of the third notch 141 are smaller than the outer dimensions of the stop 23.

[0084] In this design, the outer dimensions of the third notch 141 are smaller than those of the stop block 23, making it difficult for the stop block 23 to pass through the third notch 141. This restricts the pad strip 2 from completely sliding out of the groove 11 and detaching from the connection with the plate 1, reducing the risk of the pad strip 2 falling off and being lost.

[0085] A machining fixture includes the aforementioned jaw plates and a flat vise body 5. Two jaw plates are provided, and the two jaw plates are detachably and fixedly connected to the fixed jaw 51 and the movable jaw 52 in the flat vise body 5, respectively. The two grooves 11 are located on two opposite planes of the two plates 1.

[0086] In this scheme, the two plates 1 are fixedly connected to the fixed jaw 51 and the movable jaw 52 respectively by bolts, welding or other means, and the top surfaces of the two plates 1 are coplanar, so that the two top surfaces of the two pads 2 at the same height in the two plates 1 are coplanar, so as to stably support and lift the workpiece.

[0087] 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.
