Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an economical high temperature resistant clamping mechanism. Background Art

[0002] In the field of mechanical automation, especially in the high-temperature processing of various electronic products, glass products and metal parts (such as drying process and hot bending process), there are high requirements for the high-temperature resistance and stability of the carrier clamping mechanism. The existing clamping mechanism may have problems such as complex structure, high cost and low efficiency. In addition, under long-term high-temperature working environment, some parts of the mechanism are easily deformed or damaged by heat, affecting their service life and precision.

[0003] Deficiencies of existing technology:

[0004] 1. The traditional clamping mechanism design may use slide rails and other methods to control the opening and closing action of the clamping jaws. This type of design not only increases the complexity of the mechanism and increases the production cost, but also under long-term high-temperature working conditions, the slide rails are prone to increased wear due to thermal expansion, affecting the stability and accuracy of the mechanism.

[0005] 2. Some high-temperature clamping devices on the market may not fully consider economy and durability, lack an effective reset mechanism, and cannot ensure that the clamping jaws return to their initial position in a timely and reliable manner after the power source is released, thus affecting the efficiency of continuous operation and the processing quality of the product.

[0006] Therefore, the prior art has deficiencies and needs further improvement. Utility Model Content

[0007] In view of the problems existing in the prior art, the utility model provides an economical high temperature resistant clamping mechanism.

[0008] To achieve the above purpose, the specific scheme of the utility model is as follows:

[0009] The utility model provides an economical high temperature resistant clamping mechanism, comprising:

[0010] A clamping assembly is provided with a pair of clamping jaws, which are used to realize the release and clamping functions by opening and closing the clamping jaws;

[0011] A power assembly, used for opening and closing the traction clamp;

[0012] A reset assembly, connected to the clamping assembly, and used for resetting the clamping assembly after the power assembly releases the traction force;

[0013] The clamping assembly comprises: a clamping claw, a mounting plate, a supporting seat, a first rotating shaft, a second rotating shaft, a first cam, a second cam, and a connecting rod;

[0014] Two support seats are arranged on the left and right sides of the mounting plate, the first rotating shaft is installed on the two support seats on the left side, and the second rotating shaft is installed on the two support seats on the right side, and a clamping claw is installed at both ends of the first rotating shaft and the second rotating shaft respectively;

[0015] A first cam is disposed on the upper side of the first rotating shaft, and a second cam is disposed on the lower side of the second rotating shaft;

[0016] The first cam is rotatably connected to the left end of the connecting rod, and the second cam is rotatably connected to the right end of the connecting rod;

[0017] The connecting rod is used to drive the first rotating shaft to rotate counterclockwise and clockwise by moving leftward and rightward, and at the same time drive the second rotating shaft to rotate clockwise and counterclockwise, so as to allow the clamping claws installed at both ends of the first rotating shaft and the second rotating shaft to clamp and release.

[0018] Furthermore, the power assembly includes: a steel wire, a fixing block, a zipper pressing block, and a pulley;

[0019] The fixing block is mounted on the upper side of the right end of the connecting rod;

[0020] The zipper pressing block is installed on the left side of the mounting plate and is also located on the left side of the first rotating shaft;

[0021] One end of the steel wire is fixed on the fixed block, bypasses the zipper pressing block, turns back, passes through the pulley, and is connected to an external cylinder;

[0022] The external cylinder is used to drive the steel wire to move to the right. After the steel wire passes around the zipper pressure block, it drives the pull rod to move to the left. The first rotating shaft rotates counterclockwise and the second rotating shaft rotates clockwise, which is used to drive the clamping claws installed on the first rotating shaft and the second rotating shaft to approach each other for clamping.

[0023] Furthermore, the reset assembly includes a reset spring and an eccentric block;

[0024] The eccentric block is mounted on the second rotating shaft, one end of the return spring is mounted on the eccentric block, and the other end is fixed on the mounting plate;

[0025] The reset spring is used to drive the second rotating shaft to reset through elastic force when the external cylinder releases the pulling force on the steel wire, and the second rotating shaft drives the first rotating shaft to reset through the connecting rod.

[0026] Furthermore, a mounting frame is respectively provided on the front side and the rear side of the mounting plate.

[0027] Further, two lateral support bearings are arranged downwardly on the lower side of the mounting frame;

[0028] The mounting frame is provided with two longitudinal support bearings in the horizontal direction.

[0029] Furthermore, a limit rod is respectively installed on the first rotating shaft and the second rotating shaft, and a limit block is set on the mounting plate at a position corresponding to the limit rod. The limit rod rotates with the first rotating shaft and the second rotating shaft and stops when it abuts against the limit block, so as to prevent the first rotating shaft and the second rotating shaft from continuing to rotate.

[0030] Furthermore, a circular hollow hole is provided on the mounting plate at the intersection of two diagonals.

[0031] The technical solution of the utility model has the following beneficial effects:

[0032] 1. Simplified structural design: By cleverly using the connecting rod and cam structure to control the opening and closing action of the clamping jaws, not only the overall structure is more simple and compact, reducing the production cost, but also it can still maintain efficient and stable working performance in high temperature environment.

[0033] 2. Improve production efficiency and reduce costs: Bearing supports are used to replace traditional slide rail designs. The bearings have low running resistance and less wear, which can effectively improve equipment operating efficiency, reduce maintenance costs, and maintain good working conditions in high temperature environments.

[0034] 3. Accurate and reliable clamping function: The cylinder in the power assembly drives the connecting rod through the wire transmission system, and then accurately adjusts the rotation direction of the first and second shafts to achieve the tightening and release of the clamping jaws. This indirect drive method not only ensures the accuracy and consistency of the clamping action, but also avoids the high temperature impact problem that may be caused by direct drive.

[0035] 4. Automatic reset mechanism: Equipped with a special reset component. When the external cylinder releases the tension on the steel wire, the reset spring will automatically drive the second shaft to reset, and then drive the first shaft to reset through the connecting rod, ensuring that the clamping mechanism can quickly return to its initial state after completing a clamping or release, which is conducive to continuous operation and improving work efficiency.

[0036] 5. Safety limit design: Limit rods and corresponding limit blocks are set on the first rotating shaft and the second rotating shaft to prevent excessive rotation of the rotating shaft from causing damage to the clamping jaws or other safety hazards, thereby enhancing the safety and service life of the entire device.

A limiting rod 501 is provided on each of the first rotating shaft 104 and the second rotating shaft 105. A limiting block 502 is provided on the mounting plate 102 at a position corresponding to the limiting rod 501.

A circular hollow hole is also provided on the mounting plate 102 at the intersection of two diagonal lines.

[0054] The principle of this utility model is as follows:

[0055] Power transmission and clamping action: The external cylinder is driven by a power assembly consisting of a steel wire 201, a fixed block 202, a zipper pressing block 203 and a pulley 204. When the cylinder is working, the steel wire 201 is pulled to move to the right. After passing through the zipper pressing block 203 and the pulley 204, the steel wire 201 acts on the right end of the connecting rod 108, causing the connecting rod 108 to move to the left. The connecting rod 108 is rotatably connected to the first cam 106 on the first rotating shaft 104 and the second cam 107 on the second rotating shaft 105, respectively. Therefore, the movement of the connecting rod 108 will drive the first rotating shaft 104 to rotate counterclockwise, while the second rotating shaft 105 rotates clockwise. This relative rotation makes the paired clamping claws 101 installed at both ends of the first rotating shaft 104 and the second rotating shaft 105 approach each other, realizing the clamping function.

[0056] Clamping mechanism reset mechanism: When the external cylinder releases the tension on the steel wire 201, the reset spring 301 in the reset assembly starts to work. One end of the reset spring 301 is mounted on the eccentric block 302 on the second rotating shaft 105, and the other end is fixed on the mounting plate 102. Under the action of the spring force, the second rotating shaft 105 is driven back to the initial position, and the first rotating shaft 104 is reset together through the connecting rod 108, so that the clamping jaws 101 are restored from the clamping state to the open state, ready for the next clamping operation.

[0057] Structural support and limit design: The mechanism uses bearings as the main support structure, replacing traditional slide rails, which improves movement efficiency and reduces costs. The mounting frames 401 on the front and rear sides of the mounting plate 102 are provided with transverse and longitudinal support bearings 403 to ensure the smooth rotation of the shaft. In addition, in order to prevent the excessive rotation of the shaft from causing the jaws 101 to open and close too much or be damaged, limit rods 501 are installed on the first shaft 104 and the second shaft 105, and limit blocks 502 are set at corresponding positions on the mounting plate 102. When the shaft rotates until the limit rod 501 abuts the limit block 502, the mechanism stops further rotation to ensure safe and reliable operation.

[0058] In summary, this economical high-temperature resistant clamping mechanism utilizes the cylinder, steel wire 201, connecting rod 108, cam and other components to work together to achieve precise opening and closing control of the clamping jaws 101 in a high-temperature environment, and has good self-resetting ability and safety assurance. It is suitable for carrier clamping operations of electronic products, glass products and metal parts in high-temperature processes such as drying and hot bending.
