Description

Technical Field

[0001] This invention relates to the field of bench vise technology, specifically a steel bench vise with a mortise and tenon structure. Background Technology

[0002] Bench vises can be traced back to ancient metalworking techniques. In order to improve work efficiency and ensure machining accuracy, craftsmen began to use simple clamps to fix workpieces. These early clamps were mostly handmade, with simple structures and single functions, and could only be used for some simple metalworking operations.

[0003] With the advent of the Industrial Revolution, machining technology developed rapidly, and the requirements for fixtures became increasingly stringent. Bench vise design gradually became standardized and serialized. From the late 19th to the early 20th century, metal cutting machine tools became widespread, and bench vise design focused on clamping force, stability, and versatility. Significant improvements were made in structure and materials, and cast iron or cast steel began to be used for manufacturing, with the introduction of standard parts such as springs and nuts.

[0004] After World War II, with the development of automation and precision machining technologies, bench vises have become more focused on lightweight design, high precision, and multifunctionality. They can not only meet the needs of various metal cutting processes but also adapt to the processing of non-metallic materials. Their structural designs have also become more diversified, with various types such as V-type, C-type, and U-type emerging to meet the needs of different workpieces and processing conditions.

[0005] Entering the 21st century, with the transformation and upgrading of the manufacturing industry, the bench vise industry has ushered in a new round of development opportunities. On the one hand, enterprises have increased their research and application of new materials and processes to improve product performance; on the other hand, by introducing advanced foreign technologies and equipment, their technological level has achieved leapfrog development. At the same time, bench vise processing technology is developing towards automation and intelligence, such as bench vises with automatic clamping and loosening functions, as well as intelligent bench vises that can be controlled by computer programs, further improving processing efficiency and precision.

[0006] A bench vise mainly consists of a vise body, clamping mechanism, jaws, base, and spring mechanism. The working principle of a bench vise is based on screw drive and inclined plane friction. When the handle is turned clockwise, the lead screw rotates in the guide nut. Since the lead screw cannot move axially, its rotational motion is converted into axial movement of the movable jaw relative to the fixed jaw, causing the movable jaw to move closer to the fixed jaw, thus clamping the workpiece. Conversely, turning the handle counterclockwise reverses the lead screw, causing the movable jaw to move away from the fixed jaw, releasing the workpiece. The cross-hatching on the jaws increases the friction with the workpiece surface, making it less prone to slippage when clamped, ensuring workpiece stability during processing. Bench vises are mainly used in machining, metalworking, repair and maintenance, and woodworking fields.

[0007] The announcement number is CN111283564A, which discloses a bench vise, including a base. A moving mechanism is provided on the upper surface of the base. A driving mechanism is fixedly connected to the opposite edges of the upper surface of the base. A clamping mechanism is fixedly connected to the opposing sidewalls of the driving mechanism and the moving mechanism. A pressing mechanism is provided on the driving mechanism. A positioning mechanism is provided on the driving mechanism at the position corresponding to the pressing mechanism. In use, the support plate is supported and limited by the T-shaped slide and the T-shaped slider. When the lead screw rotates, it can drive the support plate to move through the cooperation of the lead screw nut, and drive the two clamping blocks and the locking block to clamp the workpiece. Then, under the action of the spring, the fixing block drives the retaining ring to descend through the connecting rod, and the retaining ring engages with the toothed ring, so that the lead screw cannot rotate, thereby avoiding loosening during bench vise clamping.

[0008] The existing technologies described above still cannot solve the following technical problems: First, how to quickly and accurately clamp the workpiece to be processed; second, the damage to the surface integrity of the workpiece caused by excessive or insufficient clamping force when using a bench vise manually, which affects the quality of the workpiece; and finally, the problem of the vise malfunctioning due to incorrect assembly during factory assembly or disassembly for work purposes.

[0024] Specifically, the clamping body transmission mechanism 21 is beneficial for continuously supplying the optimal clamping force to the workpiece to be processed, ensuring the stability of the processed workpiece, improving the processing quality of the workpiece, and realizing the rapid release of clamping force after the workpiece is processed, thereby indirectly improving the workpiece processing efficiency.

[0028] In a preferred embodiment, the fast workpiece clamping auxiliary motor 11 has a built-in reduction gear set. The speed and direction of the fast workpiece clamping auxiliary motor 11 are controlled by the workpiece clamping control module 14 to improve the correction and assistance effect of manually clamping the workpiece. The addition of the reduction gear set achieves the effect of speed reduction and distance increase.

[0029] In a preferred embodiment, the power supply 15 is a small storage battery, which ensures the portability and removability of the device.

[0030] Specifically, the workpiece clamping control module 14 calls the preset MAX clamping force bearing point A0 of the workpiece to be processed in the preset data storage unit 20, and monitors the surface of the workpiece to be processed with multiple sets of tracking workpiece clamping point position sensors 8, and accurately monitors the actual MAX clamping force bearing point A1 of the workpiece to be processed. Then: If A0 > A1, then the data comparison unit 17 in the workpiece clamping control module 14 determines it to be the first tracking and positioning working mode; If A0 < A1, then the data comparison unit 17 in the workpiece clamping control module 14 determines it to be the second tracking and positioning mode.

[0031] Specifically, the multiple sets of eight tracking workpiece clamping point sensors monitor the surface depth of the workpiece to be processed at multiple points, ensuring the quality of the workpiece monitoring data and laying a practical data foundation for accurately determining the MAX clamping force bearing point of the actual workpiece to be processed. Through the precise, intelligent and efficient judgment of the workpiece clamping control module 14, various types of workpieces to be processed can be replaced efficiently, preventing workpiece surface damage and affecting workpiece quality due to excessive or insufficient clamping force.

[0032] Specifically, if the data comparison unit 17 in the workpiece clamping control module 14 determines that the first tracking and positioning mode is enabled, then the data correction unit 18 in the workpiece clamping control module 14 determines that the first tracking and positioning correction mode is enabled, and the correction coefficient Q1 is: Q1= A Wherein, A represents the volume of the workpiece to be processed monitored by the tracking workpiece clamping point sensor 8. The data comparison unit 17 in the workpiece clamping control module 14 filters and matches preset data vector values. If the data comparison unit 17 in the workpiece clamping control module 14 determines that the second tracking and positioning mode is selected, then the data correction unit 18 in the workpiece clamping control module 14 determines that the second tracking and positioning correction mode is selected, and the correction coefficient Q2 is: Q2= .

[0033] Specifically, based on the first tracking and positioning correction method or the second tracking and positioning correction method, the MAX clamping force point of various workpieces to be processed is accurately positioned as the optimal clamping positioning point. At the same time, the fast workpiece clamping auxiliary motor 11 is used to achieve the effect of fast clamping, thereby improving processing efficiency.

[0034] Specifically, the workpiece clamping control module 14 calls the preset rapid workpiece clamping torque Z0 in the preset data storage unit 20, and the multiple sets of crank handle angular velocity sensors 10 accurately monitor the actual rapid workpiece clamping torque Z1 of the clamp body transmission mechanism 21, then: If Z0 > Z1, then the data comparison unit 17 in the workpiece clamping control module 14 determines it to be the first workpiece clamping working mode. If Z0 < Z1, then the data comparison unit 17 in the workpiece clamping control module 14 determines it to be the second workpiece clamping working mode.

[0035] Specifically, the workpiece clamping control module 14 determines whether the device is in the first workpiece clamping working mode or the second workpiece clamping working mode. On the one hand, this helps to improve the clamping efficiency of the device and meet the optimal clamping torque for clamping various types of workpieces to be processed, thus protecting the surface of the workpieces to be processed. On the other hand, when changing workpieces to be processed, the device can quickly release the clamping torque, thereby improving processing efficiency.

[0036] Specifically, if the data comparison unit 17 in the workpiece clamping control module 14 determines it to be the first workpiece clamping working mode, then the data correction unit 18 in the workpiece clamping control module 14 determines it to be the first workpiece clamping torque correction mode, and the correction coefficient V1 is: V1= in, Human torque value, The torque value of the fast workpiece clamping auxiliary motor 11; If the data comparison unit 17 in the workpiece clamping control module 14 determines that it is the second workpiece clamping working mode, then the data correction unit 18 in the workpiece clamping control module 14 determines that it is the second workpiece clamping torque correction mode, and the correction coefficient V2 is: V2= .

[0037] Specifically, based on either the first workpiece clamping torque correction method or the second workpiece clamping torque correction method, the second clamping body 4 achieves rapid axial movement; this improves the precision control of the clamping torque of the second clamping body 4 and enables... The clamping torque is increased, improving the speed of changing workpieces and increasing work efficiency.

[0038] Specifically, the workpiece clamping control module 14 calls the preset magnetization amount P0 of the first strong magnetic contact group 12 and the second strong magnetic contact group 13 in the preset data storage unit 20, and compares it with the actual magnetization amount P1 of the first strong magnetic contact group 12 and the second strong magnetic contact group 13. Then: If P0 > P1, then the data comparison unit 17 in the workpiece clamping control module 14 determines it to be the first disassembly and positioning method; If P0 < P1, then the data comparison unit 17 in the workpiece clamping control module 14 determines it to be the second disassembly and positioning method.

[0039] Specifically, based on the first or second disassembly and positioning method, when disassembling and assembling the equipment, it assists workers in quickly and accurately disassembling and assembling parts, indirectly improving the disassembly speed and assembly accuracy of the equipment.

[0040] Working principle and usage process of this invention: Operating Condition 1: When the base 1 is assembled with the clamp body transmission mechanism 21, the data comparison unit 17 in the workpiece clamping control module 14 determines whether it is the first or the second disassembly and positioning method. If it is the first disassembly and positioning method, the base 1 and the clamp body transmission mechanism 21 are disassembled and positioned. Then the data correction unit 18 reduces the magnetization amount P0 of the first strong magnetic contact group 12 and the magnetization amount P1 of the second strong magnetic contact group 13 to achieve the purpose of assisting quick disassembly. If the second disassembly and positioning method is used to perform the assembly and positioning process of the base 1 and the clamp transmission mechanism 21, the data correction unit 18 increases the magnetization amount P0 of the first strong magnetic contact group 12 and the magnetization amount P1 of the second strong magnetic contact group 13 to achieve the purpose of rapid auxiliary identification and assembly positioning.

[0041] Working Condition 2: The workpiece to be processed is placed between the first clamp 3 and the second clamp 4. The multiple sets of tracking workpiece clamping point sensors 8 monitor the workpiece and the surfaces of the workpiece to be processed in real time and comprehensively. The monitoring data is transmitted in real time through the data input unit 16 to the data comparison unit 17 in the workpiece clamping control module 14. The data model analysis results are processed by the data correction unit 18 and the judgment processing signal is transmitted through the data output unit 19 to the fast workpiece clamping auxiliary motor 11 to correct the torque and direction of the second clamp transmission rod 5. Finally, the second clamp 4 moves quickly towards the first clamp 3 to achieve the purpose of fast clamping of the workpiece.

[0042] Working Condition 3: When the crank handle 6 is manually operated to clamp the workpiece, the angular velocity data of the second clamp body transmission rod 5 is monitored by the crank handle angular velocity sensor 10 and transmitted in real time through the data input unit 16 to the workpiece clamping control module 14. The data comparison unit 17 and the preset data storage unit 20 analyze the data model results, which are then processed by the data correction unit 18. The judgment and processing signal is then transmitted through the data output unit 19 to the rapid workpiece clamping auxiliary motor 11. The rapid workpiece clamping auxiliary motor 11 applies a positive or negative torque to the second clamp body transmission rod 5 to adjust the clamping force caused by manual operation of the crank handle. This adjusts the clamping force, which may be too large or too small, resulting in insufficient clamping force on the workpiece or damage to the workpiece surface due to excessive clamping force, thus affecting the workpiece quality.

[0043] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
