Abstract
Description
Technical Field
[0001] This utility model relates to a mechanical clamping device, and more particularly to a compact wedge clamping mechanism. Background Technology
[0002] In industrial production, especially during the welding of box-type products, clamping operations are often required in confined spaces. Traditional clamping mechanisms, due to their large size and complex structure, are difficult to adapt to these special working conditions. Existing clamping devices typically employ a direct drive method, with the direction of movement aligned with the clamping direction. While this structure works properly in open spaces, it is often ineffective in confined spaces. Particularly during welding operations in the middle sections of box-type products, conventional clamping mechanisms cannot be installed and used due to space limitations, leading to compromised welding quality and severely impacting operator efficiency.
[0003] Currently, the market lacks a mechanism capable of reliable clamping within confined spaces, which has become a technological bottleneck restricting the improvement of production efficiency in related fields. Existing solutions often simplify the structure or reduce the clamping force, but this leads to problems such as weak clamping and poor positioning accuracy, failing to meet the process requirements of high-quality welding. Therefore, how to achieve stable clamping under space-constrained conditions through structural innovation, while maintaining sufficient clamping force and ease of operation, is a technical challenge that urgently needs to be solved in this field.

Detailed Implementation
[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0036] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0037] In existing technologies, traditional clamping mechanisms typically employ direct vertical pressure or independent horizontal drive structures, which offer good operational capabilities in open spaces. However, in confined work environments such as welding of box-type products, traditional clamps are often too large or have limited movement trajectories, making it difficult to effectively perform clamping operations. This results in inconsistent welding quality and reduced operational efficiency.
[0038] To address these issues, designers observed an operable gap in the vertical direction within the confined space, while the horizontal pressing path was obstructed. Based on the concept of spatial transformation, they attempted to kinematically couple the vertical drive with the horizontal pressing. Analysis of the mechanical transmission principle revealed that the inclined plane structure could achieve motion direction conversion, but conventional inclined plane mechanisms suffer from high stroke loss and a loose structure. After multiple structural optimizations, a dual limiting mechanism combining longitudinal guiding constraints and lateral sliding constraints was determined, along with a matching inclined plane contact surface designed to improve transmission efficiency.
[0039] In some of these embodiments, such as Figure 1 and Figure 2As shown, based on the above design concept, this application proposes a compact wedge clamping mechanism, including a fixed base 100, a longitudinal drive assembly 200 disposed on the top of the fixed base 100, and a transverse clamping assembly 300 disposed on the bottom of the fixed base 100. A diagonal push rod 220 is connected to the telescopic shaft of the longitudinal drive assembly 200. The diagonal push rod 220 is longitudinally telescopically disposed within the axial guide hole 101 on the fixed base 100, and a first inclined surface 221 is provided on one side of the top end of the diagonal push rod 220. A transversely movable T-shaped slider 320 and a pressure block 330 are disposed on the guide slide 310 of the transverse clamping assembly 330. A wedge block 340 is disposed at the rear end of the T-shaped slider 320 and the pressure block 330, and a second inclined surface 341 corresponding to the first inclined surface 221 is disposed at the lower end of the outer wall of the wedge block 340.
[0040] The fixed base 100 is a support structure that supports the longitudinal drive assembly 200 and the transverse clamping assembly 300. It can be made of a cast or machined metal substrate, and its internal axial guide hole 101 provides vertical motion trajectory constraint for the inclined push rod 220. The longitudinal drive assembly 200 is a power source that generates vertical linear motion, and can be implemented using a cylinder, hydraulic cylinder, or electric push rod. Its telescopic shaft is rigidly connected to the inclined push rod 220 to transmit driving force. The inclined push rod 220 is a transmission component with an inclined working surface, and can be manufactured from high-carbon steel through a heat treatment process. Its first inclined surface 221 at the top forms a sliding contact pair with the second inclined surface 341 of the wedge block 340. The transverse clamping assembly 300 is a functional module containing a horizontally moving clamping component, and can be fixed to the top of the fixed base 100 by bolt connection. Its guide slide 310 has a T-shaped slide rail 320 inside to provide horizontal movement guidance for the pressure block 330.
[0041] Specifically, such as Figure 3 and Figure 4 As shown, after the longitudinal drive assembly 200 is started, its telescopic shaft drives the inclined push rod 220 to move vertically along the axial guide hole 101. When the inclined push rod 220 moves upward, the first inclined surface 221 at the top contacts and slides with the second inclined surface 341 of the wedge block 340, decomposing the vertical thrust into a horizontal component. This component pushes the wedge block 340 to move laterally along the guide slide 310, causing the T-shaped slider 320 and the pressure block 330 to move synchronously to complete the clamping action. The axial guide hole 101 forms a rigid constraint on the longitudinal movement of the inclined push rod 220, preventing deflection during transmission. The guide groove (311) in the guide slide 310 limits the movement path of the T-shaped slider 320 and the pressure block 330, ensuring that the direction of the clamping force is precisely controllable. The angle matching design of the first inclined surface 221 and the second inclined surface 341 makes the vertical stroke and the horizontal stroke form a predetermined proportional relationship, maximizing the motion conversion efficiency.
[0042] Compared to existing technologies, conventional clamping mechanisms require separate vertical and horizontal drive units, resulting in complex structures and large space requirements. This solution simplifies the power system and reduces the overall size by using a single longitudinal drive source in conjunction with an inclined plane transmission mechanism. Traditional inclined plane clamping mechanisms are prone to transmission deviations and energy losses due to the lack of motion trajectory constraints, while the dual limiting structure of the axial guide hole 101 and T-shaped slider 320 in this solution significantly improves transmission accuracy and energy utilization.
[0043] Through the above technical solution, this application effectively solves the technical problem of the clamping mechanism being unable to operate in confined spaces. The integrated design of longitudinal drive and lateral clamping reduces the overall size of the mechanism, making it suitable for confined spaces such as inside a box. The inclined plane transmission structure converts the unidirectional driving force into precise clamping action, avoiding the complexity of coordinating and controlling multiple power sources. The guide constraint mechanism ensures the linear transmission characteristics of the clamping force, improving the stability and reliability of welding operations.
[0044] In some of these embodiments, such as Figure 1 and Figure 2 As shown, this application further proposes that the fixing base 100 is a square column structure, with a through axial guide hole 101 at its axial center, and a pressing mounting plate 102 at a corner of its top. The pressing mounting plate 102 has symmetrically arranged third inclined surfaces 103 on both the left and right sides of its front end.
[0045] The square column structure refers to a support component with a regular geometric shape, which can be made of aluminum alloy or stainless steel. Its planar contact surface can improve installation stability and reduce space occupation. The axial guide hole 101 refers to an internal cavity channel that runs along the axis of the fixed base 100. It can be machined using precision drilling technology and is used to constrain the longitudinal movement trajectory of the inclined push rod 220. The clamping mounting plate 102 refers to a connecting base integrally formed and set at the top corner of the fixed base 100. The third inclined surface 103 refers to the inclined guide surfaces located on both sides of the front end of the clamping mounting plate 102.
[0046] In some of these embodiments, such as Figure 1 and Figure 2 As shown, this application further proposes a longitudinal drive assembly 200 including a drive cylinder 210 and a slanted push rod 220. The drive cylinder 210 is fixedly installed at the bottom of the fixed base 100, and its telescopic rod is disposed in the axial guide hole 101 and detachably connected to the lower end of the slanted push rod 220 through a cylinder connector 211. The top end of the slanted push rod 220 is provided with a first inclined surface 221 on the side near the wedge block 340, and the upper and lower corners of the first inclined surface 221 are smoothly transitioned in an arc shape.
[0047] The driving cylinder 210 is fixedly installed at the bottom of the fixed base 100, meaning that the cylinder body is fixed to the bottom surface of the fixed base 100 by bolts or clips, such as a flange connection, which facilitates stable output of longitudinal driving force in confined spaces. The detachable connection means that the telescopic rod is connected to the inclined push rod 220 via a threaded sleeve or pin through the cylinder connector 211, such as a quick-release joint structure, for easy separation of components during maintenance. The smooth arc transition at the upper and lower corners of the first inclined surface 221 means that the intersection of the inclined surface with the vertical surface of the side wall or with the horizontal surface of the top is machined into a rounded corner or a gradually curved surface, such as using an arc transition with a radius ranging from 0.5 to 2 mm, which can reduce stress concentration on the contact surface.
[0048] Specifically, such as Figure 3 and Figure 4 As shown, when the drive cylinder 210 starts, its telescopic rod pushes the inclined push rod 220 upward along the axial guide hole 101. The first inclined surface 221 at the top of the inclined push rod 220 contacts the second inclined surface 341 of the wedge block 340. Since the upper and lower ends of the first inclined surface 221 adopt an arc transition, when the inclined push rod 220 rises to the contact position, the contact area of the inclined surface gradually transitions from the arc segment to the plane segment, avoiding rigid impact. When the drive cylinder 210 retracts, the inclined push rod 220 drives the inclined surface to disengage from the contact. The arc transition segment allows the wedge block 340 to slide smoothly along the curved surface during the reset process, reducing the frictional resistance when the lateral clamping assembly 300 moves.
[0049] In some of these embodiments, such as 1 and Figure 2 As shown, this application further proposes to open a buffer clearance groove 222 on the side wall of the top of the inclined push rod 220 near the wedge block 340. The top of the buffer clearance groove 222 is connected to the lower end of the first inclined surface 221 and has a smooth arc transition.
[0050] The buffer clearance groove 222 refers to the recessed area located on the top side wall of the inclined push rod 220. It can be formed by milling or casting. Its depth and width are designed according to the contact trajectory between the inclined push rod 220 and the wedge 340, and are used to provide transition space for the wedge 340 to disengage when the inclined push rod 220 retracts. The arc-shaped smooth transition means that the contour of the connection between the buffer clearance groove 222 and the first inclined surface 221 is connected by an arc shape, which is used to eliminate right angle or sharp angle edges and reduce stress concentration on the contact surface.
[0051] Specifically, such as Figure 3 and Figure 4As shown, when the longitudinal drive assembly 200 drives the inclined push rod 220 to retract downwards, the second inclined surface 341 of the wedge block 340 slides along the first inclined surface 221 to the buffer clearance groove 222 area. Because the arc-shaped contour of the buffer clearance groove 222 smoothly connects with the lower end of the first inclined surface 221, the wedge block 340 gradually enters the clearance space during the disengagement process, avoiding instantaneous impact caused by abrupt changes in the contact surface. The arc transition further disperses the contact stress between the inclined push rod 220 and the wedge block 340, reducing sliding friction resistance and ensuring that the lateral clamping assembly 300 smoothly retracts to its initial position under the action of the return spring 350.
[0052] In some of these embodiments, such as Figure 1 and Figure 2 As shown, this application further proposes a transverse clamping assembly 300 including a guide slide 310, a T-shaped slider 320, a pressure block 330, and a wedge block 340. The guide slide 310 is detachably mounted on the clamping mounting plate 102 of the fixed base 100 with bolts, and the T-shaped slider 320 is slidably disposed in the guide grooves 311 on both inner sides of the guide slide 310. The pressure block 320 is a triangular block structure, which is detachably mounted on the top of the T-shaped slider 320 with bolts. Its front end is an L-shaped corner structure, and its rear end is connected to the wedge block 340 through a connecting block 331. The second inclined surface 341 on the outer side of the lower end of the wedge block 340 is an outwardly convex arc-shaped inclined surface, and its upper end is detachably connected to the T-shaped slider 320 and the connecting block 330 with bolts respectively.
[0053] Among them, the guide slide 310 refers to the support structure used to guide lateral movement. Specifically, it can be implemented using a metal seat with a guide groove 311, and is detachably installed to the fixed seat 100 by bolt connection, facilitating overall disassembly for maintenance. The T-shaped slider 320 refers to a sliding component with a T-shaped cross-section, and can be implemented using a metal block that matches the guide groove 311. Lateral movement is guided through sliding engagement. The triangular structure of the pressure block 330 refers to a three-dimensional geometric shape with an L-shaped corner at the front end. Specifically, it can be cut and formed from a steel plate, and is connected to the T-shaped slider by bolts. The stability of the triangle enhances the rigidity of the pressing part. The fifth inclined surface 333 on both sides can be used as the contact surface with the box product as needed. The outwardly convex arc-shaped inclined surface of the wedge block 340 is a curved surface structure that protrudes outwards. Motion conversion is achieved through contact with the inclined surface of the inclined push rod 220.
[0054] Specifically, such as Figure 1 and Figure 2As shown, the guide slide 310 is fixed to the clamping mounting plate 102 of the fixed base 100 by bolts, forming a stable mounting base. The T-shaped slider 320 is embedded in the guide groove 311 and can slide freely in the lateral direction. The pressure block 330 is fixed to the top of the T-shaped slider 320 by bolts, and its front L-shaped structure can adapt to the contour of the box product. When the inclined push rod 220 moves upward, its first inclined surface 221 contacts the second inclined surface 341 of the wedge block 340, pushing the wedge block 340 to drive the T-shaped slider 320 and the pressure block 330 to move laterally, thereby pressing the box product. The T-shaped slider 320 and the pressure block 330 are linked with the outer wedge block 340 to form a force transmission path. The bolted connections between the components allow for individual disassembly. For example, when the pressure block 330 is worn, it can be replaced by removing only the corresponding bolts without disassembling the entire assembly.
[0055] In some of these embodiments, such as Figure 1 and Figure 2 As shown, this application further proposes that the left and right side walls of the front end of the guide slide 310 are respectively provided with symmetrically arranged fourth inclined surfaces 312, the rear end is open, and the inner side wall of the upper end is symmetrically provided with a guide groove 311 that runs through the front and rear. The fourth inclined surface 312 corresponds to the third inclined surface 103 on the fixed seat 100 and is arranged flush with it.
[0056] The fourth inclined surface 312 refers to the symmetrical inclined surfaces formed on both sides of the front end of the guide slide 310. Its inclination angle corresponds vertically to the third inclined surface 103 of the fixed base 100, and is used to achieve self-positioning during assembly. The open rear end means that the rear side of the guide slide 310 is not enclosed, which provides clearance for the movement of the T-shaped slider and facilitates the installation of the return spring 350. The flush arrangement means that the fourth inclined surface 312 and the third inclined surface 103 are on the same plane after installation, which maintains the continuity of the mechanism's appearance and avoids motion interference.
[0057] In some of these embodiments, such as Figure 1 and Figure 2 As shown, this application further proposes that the rear end of the connecting block 331 is provided with a horizontally extending limiting baffle 332, the bottom of the limiting baffle 332 abutting against the top of the wedge block 340. The limiting baffle 332 refers to a plate-like structure extending from the rear end of the connecting block 331, its extension direction being parallel to the movement direction of the transverse pressing assembly 300. Specifically, it can be implemented using an integrally formed or bolted metal plate, used to limit the relative displacement between the connecting block 311 and the wedge block 340.
[0058] Specifically, such as Figure 3 and Figure 4As shown, when the longitudinal drive assembly 200 drives the inclined push rod 220 to move, the wedge block 340 experiences lateral displacement due to the interaction between the first inclined surface 220 and the second inclined surface 341. The limiting baffle 333 covers the top of the wedge block 340 through a horizontally extending plate, and its bottom forms a contact constraint with the top surface of the wedge block 340, preventing relative movement between the connecting block 331 and the wedge block 340 in the vertical direction. When the clamping mechanism is subjected to external loads, the rigid support of the limiting baffle 333 can counteract the misalignment tendency between the connecting block 331 and the wedge block 340 caused by vibration or impact, ensuring that they always maintain a stable contact state.
[0059] In addition, such as Figure 2 As shown, this application further proposes that the left and right sides of the L-shaped corner structure at the front end of the pressure block 330 form a fifth inclined surface 333, the front end connection of the two fifth inclined surfaces 333 is smoothly transitioned in an arc shape, and the included angle between the two fifth inclined surfaces 333 is greater than or equal to the included angle between the two fourth inclined surfaces 312 at the front end of the lower guide slide 310.
[0060] The fifth inclined surface 333 refers to the two outer side walls of the L-shaped corner structure at the front end of the pressure block 330. When the pressure block 330 moves laterally, the fifth inclined surface 333 has a certain angle difference with the direction of movement. When this fifth inclined surface 333 serves as the contact surface with the box product, it can push the box product to move in the X direction while simultaneously moving it to a certain extent in the Y direction, achieving clamping of the box product in a confined space. The smooth, rounded transition at the front end connection of the two fifth inclined surfaces 333 refers to the rounded corner structure at the front end of the pressure block 330. When this rounded corner serves as the contact surface with the box product, it can reduce stress concentration on the contact surface to a certain extent. Rubber gaskets can be installed at this rounded corner as needed to further reduce stress concentration on the contact surface.
[0061] In some of these embodiments, such as Figure 1 and Figure 2 As shown, this application further proposes that the lateral clamping assembly 300 also includes a return spring 350. The return spring 350 is disposed in the cavity at the lower end of the guide slide 310, with one end fixedly connected to the guide slide 310 and the other end abutting against the inner wall of the lower end of the wedge block 340. The return spring 350 is an elastic element used to provide a reverse force, and can be implemented using a helical compression spring. The abutting connection refers to a contact but not fixed engagement between the return spring and the inner wall of the lower end of the wedge block. Specifically, this can be achieved by the spring end face fitting against a pre-reserved groove in the wedge block 340, allowing the spring to push the wedge block 340 backward to return to its original position when it rebounds.
[0062] Specifically, such as Figure 3 and Figure 4As shown, when the longitudinal drive assembly 200 drives the inclined push rod 220 downward, the first inclined surface 221 and the second inclined surface 341 disengage. The return spring 350 releases its elastic potential energy from the compressed state, and its rebound force acts on the inner wall of the lower end of the wedge block 340 through the abutment surface, pushing the wedge block 340 to slide in the opposite direction, driving the T-shaped slider 320 and the pressure block 330 to move along the guide groove 311 to the initial position. During this process, the fixed end of the return spring 350 remains in a stable position, and the movable end realizes the relative movement between the wedge block 340 and the guide slide 310 through the linear abutment force, ultimately causing the clamping assembly to fully reset.
[0063] Through the above technical solution, this application achieves the automatic reset function when the clamping mechanism is released, solving the problem that moving parts cannot return to their original position due to friction or gravity. The linear rebound force of the reset spring 350 acts directly on the movement direction of the wedge block 340, ensuring a smooth and reliable reset process. The cavity of the guide slide 310 constrains the spring, preventing the elastic element from shifting and improving the stability of the mechanism's operation. This design integrates power transmission and reset functions within a limited space, meeting the compact layout requirements of confined working environments.
[0064] In some of these embodiments, such as Figure 1 and Figure 2 As shown, this application further proposes that the lateral clamping assembly 300 also includes a buffer pad 360, which is disposed between the inner sidewall of the upper end of the wedge block 340 and the rear end sidewall of the T-slider 320 and the pressure block 330. The buffer pad 360 refers to an elastic element disposed between the contact surfaces of the moving parts, specifically made of polyurethane or rubber material, with a thickness of, for example, 0.5-2 mm, which absorbs impact energy through elastic deformation. This element is arranged in the assembly gap between the wedge block 340 and the T-slider 320 and pressure block 330, and can disperse contact stress through the compressive deformation of the material itself during the clamping process.
[0065] Combination Figures 1 to 4 As shown, the compact wedge clamping mechanism provided in this application operates on the following principle: After the parts are assembled, the drive cylinder 210 drives the cylinder connector 211 and the inclined push rod 220 to rise. The inclined surface of the inclined push rod 220 pushes the wedge block 340, buffer pad 360, T-shaped slider 320 and pressure block 330 to slide to the left at the position shown in the figure to clamp the product. At this time, the buffer spring 350 is compressed. When retracting, the drive cylinder 210 retracts, driving the cylinder connector 211 and the inclined push rod 220 to retract. The wedge block 340, buffer pad 360, T-shaped slider 320 and pressure block 330 rebound through the buffer spring 350 and retract to the position in contact with the inclined push rod 220. This structure realizes the conversion of up-and-down movement into left-and-right movement.
[0066] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
