A modular dovetail clamp assembly

Abstract

This invention belongs to the field of clamping technology and discloses a modular dovetail clamping assembly, including a base and a rotating mechanism. The rotating mechanism includes a first bidirectional threaded shaft and a first helical gear, with the first bidirectional threaded shaft rotatably connected to the base. Through the design of structures such as sliding seats, a stabilizing mechanism, and an adjusting mechanism, the rotation of the first bidirectional threaded shaft drives two sliding seats to move synchronously in opposite directions. The bonding plate contacts and presses against the inclined edge of the dovetail groove, gradually tilting until it matches the inclination of the dovetail groove's inclined edge. As the two sliding seats continue to move in opposite directions, the pressure between the bonding plate and the inclined edge of the dovetail groove gradually increases. Furthermore, as the first piston column gradually shortens, the sliding block moves away from the bonding plate under pressure, thereby compressing the spring. Under the reaction force, the bonding plate and the inclined edge of the dovetail groove fit together more closely.

Description

Technical Field

[0001] This invention belongs to the field of fixture technology, specifically a modular dovetail fixture assembly. Background Technology

[0002] A dovetail clamp is a tool used to fix or support objects. It typically has one or more dovetail-shaped slots that can be used with corresponding parts. The design of dovetail clamps makes them very useful in machining, assembly, or other applications requiring precise positioning and fixation. They ensure high positioning accuracy of the clamped parts in three dimensions, provide stable support, reduce vibration during machining, and thus improve machining quality.

[0003] Existing dovetail jigs typically involve first milling a groove on the bottom of the workpiece to fit the jig, then aligning the jig with the workpiece, and finally adjusting and locking the clamping device on the dovetail jig to secure the workpiece. However, if there is an error in the slope of the dovetail groove edge during milling, the contact area between the clamping device and the dovetail groove on the bottom of the workpiece will be reduced during fixing, resulting in a poorer fixing effect and making it easier to produce errors during workpiece machining. Therefore, improvements are proposed to address these issues. Summary of the Invention

[0004] To address the issue raised in the background art that the slope of the groove edge at the bottom of the workpiece is inaccurate, which leads to a smaller contact area between the clamping device and the dovetail groove at the bottom of the workpiece during fixing, resulting in a poorer fixing effect and consequently causing errors during workpiece processing, this invention provides a modular dovetail clamping assembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular dovetail clamp assembly, including a base, and further comprising:

[0006] A rotating mechanism, comprising a first bidirectional threaded shaft and a first helical gear, wherein the first bidirectional threaded shaft is rotatably connected to a base; and...

[0007] A transmission mechanism, comprising a fixed base, a connecting column, a second helical gear, a third helical gear, and a limiting stop, wherein the fixed base is fixedly installed in the middle of the inner cavity of the base; and,

[0008] A fixing mechanism, comprising a positioning housing, a fourth helical gear, a second bidirectional threaded shaft, a movable block, and a limiting assembly, the limiting assembly being rotatably connected to the upper end of the connecting column; and,

[0009] A sliding seat, slidably connected to the interior of the base and disposed on the surface of the rotating mechanism; and,

[0010] A stabilizing mechanism, comprising a fixed housing, a sliding block, a positioning post, and a spring, wherein the fixed housing is fixedly mounted on the top of the sliding seat; and,

[0011] An adjustment mechanism, comprising a first piston rod, a second piston rod, a connecting plate, and a bonding plate, wherein the first piston rod is connected to the fixed housing.

[0012] Preferably, the first helical gear is fixedly mounted on the surface of the first bidirectional threaded shaft and located inside the fixed seat, and the first bidirectional threaded shaft is rotatably connected to the fixed seat.

[0013] Preferably, the connecting column is rotatably connected to the fixed base, the second helical gear is fixedly installed at the bottom of the connecting column and meshes with the first helical gear, the third helical gear is fixedly installed at the top of the connecting column and meshes with the fourth helical gear, and the limiting block is fixedly installed at the top of the fixed base.

[0014] Preferably, the fourth helical gear is fixedly installed on the surface of the second bidirectional threaded shaft, the second bidirectional threaded shaft is rotatably connected to the inside of the positioning housing, the movable block is slidably connected to both ends of the positioning housing and threadedly connected to the second bidirectional threaded shaft, and the limiting component is fixedly installed on the bottom of the positioning housing.

[0015] Preferably, the sliding block is connected to the piston of the fixed housing, the positioning post passes through the sliding block at one end located outside the fixed housing, the positioning post is fixedly connected to the fixed housing, and the spring is movably sleeved on the surface of the positioning post with one end in contact with the sliding block.

[0016] Preferably, the second piston rod is connected to the fixed housing, one end of the connecting plate is hinged to the second piston rod, and the other end of the connecting plate is hinged to the bonding plate.

[0017] Preferably, the interior of the fixed housing is filled with hydraulic oil, the first piston rod and the second piston rod are connected through the fixed housing, and the spring is in a compressed state.

[0018] Preferably, there are two limiting blocks connected by the central axis of the limiting component, forming an angle of 90 degrees. The limiting component will be blocked by the limiting blocks after rotating 90 degrees.

[0019] Preferably, the limiting component includes a rotating block and a positioning block, one side of the rotating block is fixedly installed with the positioning block, the bottom surface of the rotating block does not contact the top surface of the fixed seat, and the rotating block overlaps the surface of the connecting column.

[0020] Preferably, the pitch of the second bidirectional threaded shaft surface is greater than the pitch of the first bidirectional threaded shaft surface. When the first bidirectional threaded shaft rotates and drives the two sliding seats to move synchronously in opposite directions, the limiting component first rotates 90 degrees, and then the movable block moves out from inside the positioning housing and gradually squeezes the sliding block.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] This invention, through the design of a sliding seat, a stabilizing mechanism, and an adjusting mechanism, uses the rotation of a first bidirectional threaded shaft to drive two sliding seats to move synchronously in opposite directions. The bonding plate contacts and presses against the inclined edge of the dovetail groove, gradually tilting, and its tilt gradually becomes the same as the inclination of the dovetail groove. When the middle of the bonding plate contacts the inclined edge, it means that the inclination of the bonding plate is the same as the inclination of the dovetail groove. On this basis, the continued back-to-back movement of the two sliding seats will gradually increase the pressure between the bonding plate and the inclined edge of the dovetail groove, and at the same time, the first piston column will gradually shorten. The shortening of the first piston column will cause the second piston column to shorten synchronously. At this time, the sliding block will move away from the bonding plate under the pressure, thereby squeezing the spring. Under the reaction force, the bonding plate and the inclined edge of the dovetail groove fit together more closely.

[0023] This invention, through the design of a rotating mechanism, a transmission mechanism, and a fixing mechanism, uses a first bidirectional threaded shaft to drive the second helical gear and the connecting column to rotate. Since the limiting component is attached to the connecting column, under the influence of friction, the rotation of the connecting column will cause the entire fixing mechanism to rotate around the central axis of the connecting column. Furthermore, due to the limiting block that limits the rotation of the entire fixing mechanism, it is ensured that the entire fixing mechanism can only rotate 90 degrees. When it reaches 90 degrees, the rotation of the third helical gear will only drive the rotation of the fourth helical gear and the second bidirectional threaded shaft, thereby causing the two movable blocks to move synchronously in opposite directions, move out of the positioning shell, and squeeze the sliding block, thereby increasing the pressure between the bonding plate and the dovetail groove slope, further ensuring the firmness of the fixation.

Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0036] like Figures 1 to 8 As shown, the present invention provides a modular dovetail clamp assembly, including a base 1, and further comprising:

[0037] Rotating mechanism 2, comprising a first bidirectional threaded shaft 201 and a first helical gear 202, wherein the first bidirectional threaded shaft 201 is rotatably connected to the base 1; and,

[0038] Transmission mechanism 3 includes a fixed base 301, a connecting column 302, a second helical gear 303, a third helical gear 304, and a limiting block 305. The fixed base 301 is fixedly installed in the middle of the inner cavity of the base 1; and,

[0039] The fixing mechanism 4 includes a positioning housing 401, a fourth helical gear 402, a second bidirectional threaded shaft 403, a movable block 404, and a limiting assembly 405, which is rotatably connected to the upper end of the connecting column 302; and,

[0040] Sliding seat 5, which is slidably connected to the inside of base 1 and disposed on the surface of rotating mechanism 2; and,

[0041] The stabilizing mechanism 6 includes a fixed housing 601, a sliding block 602, a positioning post 603, and a spring 604. The fixed housing 601 is fixedly mounted on the top of the sliding seat 5; and...

[0042] The adjustment mechanism 7 includes a first piston rod 701, a second piston rod 702, a connecting plate 703, and a bonding plate 704. The first piston rod 701 is connected to the fixed housing 601.

[0043] The above scheme is adopted: by rotating the first bidirectional threaded shaft 201, the two sliding seats 5 threaded to the first bidirectional threaded shaft 201 can move synchronously in opposite directions, thereby contacting and pressing the workpiece that is sleeved on the outside of the adjustment mechanism 7 through the dovetail groove. Specifically, the bonding plate 704 contacts and presses the inclined side of the dovetail groove, so that the bonding plate 704 gradually tilts, and its tilting degree gradually becomes the same as the inclination of the dovetail groove. Due to the design of the second piston column 702, when the bonding plate 704 tilts, one set of the upper and lower sets of second piston columns 702 extends and the other set shortens. The second piston column 702 is connected to the fixed shell 601, which makes the upper and lower sets of second piston columns 702 always maintain a changing balance, that is, the amount of extension and the amount of shortening are equal.

[0044] Furthermore, when the middle of the bonding plate 704 contacts the inclined edge, it means that the inclination of the bonding plate 704 is the same as the inclination of the dovetail groove. On this basis, the continued back-to-back movement of the two sliding seats 5 will gradually increase the pressure between the bonding plate 704 and the inclined edge of the dovetail groove, and with the gradual shortening of the first piston column 701, the shortening of the first piston column 701 will cause the second piston column 702 to shorten synchronously. At this time, the sliding block 602 will move away from the bonding plate 704 under the action of pressure, thereby squeezing the spring 604. Under the reaction force, the bonding plate 704 and the inclined edge of the dovetail groove fit together more closely, and the positioning post 603 cooperates with the sliding block 602 to ensure that each spring 604 is subjected to the same pressure.

[0045] Furthermore, due to the meshing between the first helical gear 202 and the second helical gear 303, the rotation of the first helical gear 202 drives the rotation of the second helical gear 303, which in turn drives the rotation of the connecting column 302. Since the limiting component 405 is attached to the connecting column 302, under the influence of friction, the rotation of the connecting column 302 will cause the entire fixing mechanism 4 to rotate around the central axis of the connecting column 302. Moreover, since the limiting block 305 is provided to limit the rotation of the entire fixing mechanism 4, it is ensured that the entire fixing mechanism 4 can only rotate 90 degrees. When it reaches 90 degrees, the rotation of the third helical gear 304 will only drive the rotation of the fourth helical gear 402. The rotation of the fourth helical gear 402 will drive the rotation of the second bidirectional threaded shaft 403, thereby causing the two movable blocks 404 to move synchronously in opposite directions, move out of the positioning housing 401, and squeeze the sliding block 602, thereby increasing the pressure between the bonding plate 704 and the dovetail groove slope, ensuring a firm fixation.

[0046] like Figure 2 , Figure 3 As shown, the first helical gear 202 is fixedly installed on the surface of the first bidirectional threaded shaft 201 and located inside the fixed seat 301. The first bidirectional threaded shaft 201 is rotatably connected to the fixed seat 301.

[0047] With the above scheme, the first bidirectional threaded shaft 201 rotates only along its central axis and will not shift in position. The fixed seat 301 is fixedly connected to the base 1, and the fixed seat 301 protects the first helical gear 202.

[0048] like Figure 2 , Figure 4 As shown, the connecting column 302 is rotatably connected to the fixed base 301, the second helical gear 303 is fixedly installed at the bottom of the connecting column 302 and meshes with the first helical gear 202, the third helical gear 304 is fixedly installed at the top of the connecting column 302 and meshes with the fourth helical gear 402, and the limiting block 305 is fixedly installed at the top of the fixed base 301.

[0049] Using the above scheme: transmission can be achieved through the meshing of the first helical gear 202 and the second helical gear 303. The rotation of the first bidirectional threaded shaft 201 drives the first helical gear 202 to rotate, which in turn drives the second helical gear 303 to rotate. The second helical gear 303 drives the connecting column 302 to rotate, and the connecting column 302 drives the third helical gear 304 to rotate.

[0050] like Figure 3-5 As shown, the fourth helical gear 402 is fixedly installed on the surface of the second bidirectional threaded shaft 403, the second bidirectional threaded shaft 403 is rotatably connected to the inside of the positioning housing 401, the movable block 404 is slidably connected to both ends of the positioning housing 401 and threadedly connected to the second bidirectional threaded shaft 403, and the limiting component 405 is fixedly installed on the bottom of the positioning housing 401.

[0051] The above scheme is adopted: the positioning housing 401 limits the movable block 404, and the second bidirectional threaded shaft 403 can drive the two movable blocks 404 to move synchronously relative to each other or in opposite directions when rotating, so as to ensure the stability of movement. The meshing of the fourth helical gear 402 with the third helical gear 304 ensures that the rotation of the first helical gear 202 can drive the second bidirectional threaded shaft 403 to rotate.

[0052] like Figure 6-8 As shown, the sliding block 602 is piston-connected to the fixed housing 601. The positioning pin 603 passes through the sliding block 602 at one end located outside the fixed housing 601. The positioning pin 603 is fixedly connected to the fixed housing 601. The spring 604 is movably sleeved on the surface of the positioning pin 603, and one end of the spring 604 contacts the sliding block 602. The interior of the fixed housing 601 is filled with hydraulic oil. The first piston pin 701 and the second piston pin 702 are connected through the fixed housing 601. The spring 604 is in a compressed state. The second piston pin 702 is connected to the fixed housing 601. One end of the connecting plate 703 is hinged to the second piston pin 702, and the other end of the connecting plate 703 is hinged to the bonding plate 704.

[0053] The above scheme is adopted: the compressed spring 604 ensures that the first piston column 701 is always extended to its maximum value when it is not engaged with the dovetail groove. That is, when it is engaged with the dovetail groove for fixation, the compression of the first piston column 701 can increase the compression degree of the spring 604. The spring 604 provides a reaction force for fixation. Since the fixed housing 601 is equipped with hydraulic oil, the compressed spring 604 causes the sliding block 602 to squeeze the hydraulic oil through its elastic force. The oil pressure makes the bonding plate 704 always stick tightly to the inclined surface of the dovetail groove.

[0054] Furthermore, the connecting plate 703 allows the bonding plate 704 to deflect via a hinge, ensuring the rationality of the structure.

[0055] like Figure 5 As shown, there are two limit blocks 305, and the two limit blocks 305 are connected with the central axis of the limit component 405 as the center. The included angle formed is 90 degrees. After the limit component 405 rotates 90 degrees, it will be blocked by the limit blocks 305.

[0056] The above scheme is adopted: the limiting block 305 can restrict the rotation of the positioning shell 401 and the limiting component 405, so that they can only rotate 90 degrees. When the rotation reaches 90 degrees, the positioning shell 401 and the limiting component 405 cannot continue to rotate due to the obstruction of the limiting block 305. At this time, the rotation of the connecting column 302 and the third helical gear 304 can only drive the fourth helical gear 402 to rotate. The rotation of the fourth helical gear 402 can drive the second bidirectional threaded shaft 403 to rotate. Under the limitation of the positioning shell 401, the two moving blocks 404 move out of the positioning shell 401 in opposite directions at the same time, and gradually contact and squeeze the sliding block 602, increasing the pressure between the bonding plate 704 and the dovetail groove inclined surface, ensuring the fixing effect on the workpiece.

[0057] like Figure 3 , Figure 4 As shown, the limiting component 405 includes a rotating block 4051 and a positioning block 4052. One side of the rotating block 4051 is fixedly installed with the positioning block 4052. The bottom surface of the rotating block 4051 does not contact the top surface of the fixed seat 301. The rotating block 4051 overlaps the surface of the connecting column 302.

[0058] The above scheme is adopted: the rotating block 4051 is not in contact with the fixed base 301, so there is no friction. The connecting column 302 supports the limiting component 405, the positioning shell 401 and the movable block 404, which generates friction. The friction ensures that the entire fixed mechanism 4 rotates synchronously with the connecting column 302. When the rotation of the entire fixed mechanism 4 stops because the positioning block 4052 is blocked by the limiting block 305, the rotation of the connecting column 302 drives the fourth helical gear 402 to rotate through the third helical gear 304, thereby moving the movable block 404 out of the interior of the positioning shell 401.

[0059] like Figure 3-5 As shown, the pitch of the second bidirectional threaded shaft 403 is greater than the pitch of the first bidirectional threaded shaft 201. When the first bidirectional threaded shaft 201 rotates and drives the two sliding seats 5 to move synchronously in opposite directions, the limiting component 405 first rotates ninety degrees, and then the movable block 404 moves out from inside the positioning housing 401 and gradually squeezes the sliding block 602.

[0060] The above solution is adopted: by designing the surface pitch of the second bidirectional threaded shaft 403 and the first bidirectional threaded shaft 201, after the fixing mechanism 4 rotates 90 degrees as a whole, the movable block 404 can quickly move out of the positioning housing 401, thereby squeezing the sliding block 602, making the connection between the bonding plate 704 and the inclined surface of the dovetail groove tighter. Furthermore, since the first piston column 701 gradually shortens under pressure after the bonding plate 704 and the inclined surface of the dovetail groove are squeezed, the position of the sliding block 602 is determined by the position of the inclined surface of the dovetail groove. This makes the contact position between the sliding block 602 and the movable block 404 a range value, not a fixed point, thereby increasing its applicability.

[0061] Working principle and usage process of this invention:

[0062] In use, first place the workpiece with the dovetail groove milled on the bottom on the surface of the base 1, and make the two inclined surfaces of the dovetail groove clamp the two sets of adjustment mechanisms 7 in the middle. Then rotate the first bidirectional threaded shaft 201. The rotation of the first bidirectional threaded shaft 201 drives the first helical gear 202 to rotate. The rotation of the first helical gear 202 drives the sliding seat 5 and the second helical gear 303 to move synchronously.

[0063] The first helical gear 202 drives the two sliding seats 5 to move synchronously in opposite directions, causing the bonding plate 704 to gradually contact and press against the edge of the dovetail groove. The bonding plate 704 gradually tilts, and its tilting degree gradually becomes the same as the slope of the dovetail groove. Due to the design of the second piston column 702, when the bonding plate 704 tilts, one set of the upper and lower sets of second piston columns 702 extends and the other shortens. The second piston column 702 is connected to the fixed housing 601, which ensures that the upper and lower sets of second piston columns 702 always maintain a changing balance, that is, the amount of extension and the amount of shortening are equal. On this basis, the connecting plate 703 ensures that the bonding plate 704 can tilt normally. When the middle part of the bonding plate 704 is close to the inclined edge When in contact, it means that the inclination of the bonding plate 704 is the same as the inclination of the dovetail groove. On this basis, the continued back-to-back movement of the two sliding seats 5 will gradually increase the pressure between the bonding plate 704 and the dovetail groove, and the first piston column 701 will gradually shorten. The shortening of the first piston column 701 will cause the second piston column 702 to shorten synchronously. At this time, the sliding block 602 will move away from the bonding plate 704 under the action of pressure, thereby squeezing the spring 604. Under the reaction force, the bonding plate 704 and the dovetail groove are more closely fitted. The positioning column 603 and the sliding block 602 cooperate to ensure that each spring 604 is subjected to the same pressure.

[0064] When the rotation of the first helical gear 202 drives the rotation of the second helical gear 303, the rotation of the second helical gear 303 will drive the rotation of the connecting column 302. Since the limiting component 405 is attached to the connecting column 302, under the influence of friction, the rotation of the connecting column 302 will cause the entire fixing mechanism 4 to rotate around the central axis of the connecting column 302. Furthermore, because the limiting block 305 is provided to limit the rotation of the entire fixing mechanism 4, it ensures that the entire fixing mechanism 4 can only rotate 90 degrees. When it reaches 90 degrees, the rotation of the third helical gear 304 will only... The rotation of the fourth helical gear 402 drives the rotation of the second bidirectional threaded shaft 403, thereby causing the two movable blocks 404 to move synchronously in opposite directions and move out of the positioning housing 401. Due to the design of the surface pitch of the second bidirectional threaded shaft 403 and the first bidirectional threaded shaft 201, after the fixing mechanism 4 rotates 90 degrees as a whole, the movable block 404 can quickly move out of the positioning housing 401 and squeeze the sliding block 602, thereby increasing the pressure between the bonding plate 704 and the dovetail groove slope, ensuring a firm fixation.
