[0024] The clamping unit with a positioning detection mechanism according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Example:

[0026] Figure 1 This diagram shows a three-dimensional structural schematic of a clamping unit with a positioning detection mechanism provided in an embodiment of the present invention. Figure 2 The image shows a front view of a clamping unit with a positioning detection mechanism provided in an embodiment of the present invention; Figure 3 This illustration shows another perspective structural diagram of the clamping unit with a positioning detection mechanism provided in an embodiment of the present invention; Figure 4 A three-dimensional structural schematic diagram of the detection component provided in an embodiment of the present invention is shown; Figure 5 This diagram illustrates a three-dimensional structure of a clamping unit with a positioning detection mechanism and a workpiece status, according to an embodiment of the present invention. Figures 1 to 5As shown, this utility model embodiment provides a clamping unit with a positioning detection mechanism, which is used to detect the clamping state of a workpiece, adapting to both automation and manual intervention needs, and achieving accurate control of the clamping force. The clamping unit with a positioning detection mechanism provided in this utility model embodiment includes: a fixed base 1, a drive mechanism 2, a detection component 3, a sensing component 4, and a clamping component 5. The fixed base 1 has a mounting plate 11 on its upper part, which is used to install and fix various components on the clamping unit. The fixed base 1 is generally fixed to a workbench to achieve the installation and fixation of the entire clamping unit. The clamping component 5 is mounted on the mounting plate 11 and mechanically connected to it for mechanical fixation. The drive mechanism 2 is mounted on the mounting plate 11... The side of the mounting plate 11 is hinged to the mounting plate 11 to realize the installation and fixation of the drive mechanism 2. The drive mechanism 2 is driven to connect with the clamping assembly 5 to realize the switching of opening and clamping actions of the clamping assembly 5 to clamp or release the workpiece. The sensing assembly 4 is set on the drive mechanism 2. The detection assembly 3 is driven to connect with the drive mechanism 2 to realize the mechanical contact connection with the sensing assembly 4 under the action of the drive mechanism 2 to realize the state detection of the clamping assembly 5. The motion state detection of the detection assembly 3 is realized by mechanically connecting the limit blocks on the detection assembly 3 with the limit switches at the corresponding parts of the sensing assembly 4. Furthermore, the motion association between the detection assembly 3 and the clamping assembly 5 is realized through the piston rod 22 on the drive mechanism 2, thereby realizing the clamping state detection of the clamping assembly 5.

[0027] In the clamping unit with positioning detection mechanism provided in this embodiment of the utility model, the driving mechanism 2 further includes a driving cylinder 21 and a piston rod 22. The piston rod 22 is driven by the driving cylinder 21 to realize the reciprocating linear motion of the piston rod 22. The driving cylinder 21 is hinged to the side of the mounting plate 11 to realize the fixing and posture adjustment of the driving cylinder 21. The hinge method is used here to prevent over-positioning problems when the driving mechanism 2 moves due to the linkage mechanism formed with the mounting plate 11 and the pressure rod 51. The sensing component 4 includes an upper limit switch 41, a lower limit switch 42, and a limit bracket 43. The upper limit switch 41 and the lower limit switch 42 are mechanically connected to the drive cylinder 21 through the limit bracket 43 to sense changes in the movement position of the detection component 3. The limit bracket 43 is fixed on the drive cylinder 21, which can detect the relative position changes of the upper limit switch 41, the lower limit switch 42, and the detection component 3. The detection component 3 moves linearly along the piston rod 22, so that the positions of the detection component 3 and the sensing component 4 can be kept relatively fixed overall, while isolating the movement interference of other moving parts to the detection component 3 and the sensing component 4.

[0028] More specifically, in the clamping unit with positioning detection mechanism provided in this embodiment of the utility model, the detection component 3 includes: a detection rod 31, an upper limit block 32, a lower limit block 33, and a detection bracket 34. The detection rod 31 is mechanically connected to the piston rod 22 through the detection bracket 34 to realize the synchronous linear reciprocating motion of the detection rod 31 and the piston rod 22. The detection rod 31 and the piston rod 22 are arranged in parallel. The upper limit block 32 and the lower limit block 33 are respectively arranged at the upper and lower parts of the detection rod 31. During operation, when the piston rod 22 moves downward linearly under the drive of the drive cylinder 21, the piston rod 22 drives the detection rod 31 and its upper limit block 32 and lower limit block 33 to move downward linearly together via the detection bracket 34. At this time, the upper limit block 32 is mechanically connected to the upper limit switch 41 to detect one state of the detection rod 31 and / or the clamping assembly 5 (corresponding to the retracted state of the piston rod 22 or the open state of the clamping assembly 5). Meanwhile, the lower limit block 33 is disengaged from the lower limit switch 42. The upper limit block 32 presses the upper limit switch 41, causing the upper limit switch 41 to output an electrical signal, which is then transmitted to the external... The control system collects and judges the output electrical signal of the upper limit switch 41, and then controls the gas supply to the drive cylinder 21 through the air circuit, thereby further realizing the action control of the clamping assembly 5. Correspondingly, when the piston rod 22 moves upward linearly under the drive of the drive cylinder 21, the piston rod 22 drives the detection rod 31 and its upper limit block 32 and lower limit block 33 to move upward linearly together through the detection bracket 34. At this time, the lower limit block 33 makes mechanical contact with the lower limit switch 42 to realize another state of the detection rod 31 and / or the clamping assembly 5 (corresponding to the extended state of the piston rod 22 or the clamping state of the clamping assembly 5, such as...). Figure 1 The detection is performed in the state shown in the figure. At this time, the upper limit block 32 is disengaged from the upper limit switch 41. The lower limit block 33 squeezes the lower limit switch 42, causing the lower limit switch 42 to output an electrical signal. The external control system collects and judges the output electrical signal of the lower limit switch 42, and then controls the gas supply to the drive cylinder 21 through the air circuit, so as to further realize the action and clamping force control of the clamping component 5.

[0029] In the clamping unit with positioning detection mechanism provided in this embodiment of the utility model, as a further design improvement, the clamping assembly 5 includes: a pressure rod 51, a hinge seat 52, an upper clamping block 53, and a lower clamping block 54. The lower clamping block 54 and the hinge seat 52 are mechanically fixed to the mounting plate 11. The pressure rod 51 is hinged to the hinge seat 52, using the hinge seat 52 as the fulcrum when the pressure rod 51 performs lever movement. One end of the pressure rod 51 (i.e....) Figure 2The right end of the middle pressure rod 51 is hinged to the piston rod 22 to realize the lever movement of the pressure rod 51. The upper clamping block 53 is located above the lower clamping block 54 and is mechanically fixed to the other end of the pressure rod 51 (i.e., Figure 2 The left end of the middle pressure rod 51 is used to clamp the workpiece. The workpiece is installed between the upper clamping block 53 and the lower clamping block 54, so that it can be clamped under the drive of the piston rod 22. In this way, the piston rod 22 can simultaneously drive the pressure rod 51 and the detection rod 31 to move synchronously, realizing the motion association between the detection component 3 and the pressure rod 51. Thus, the output signal of the detection sensing component 4 can obtain the motion state change information of the pressure rod 51 in the clamping component 5, thereby judging whether the clamping component 5 is clamped in place and controlling the magnitude of the clamping force, realizing more precise control of the clamping component 5, and preventing some easily deformable or thin plate workpieces with limited load-bearing capacity from being subjected to large force deformation.

[0030] In the clamping unit with positioning detection mechanism provided in this embodiment of the utility model, as a further design improvement, the clamping assembly 5 also includes: a positioning block 55, and the pressure rod 51 is positioned and contacted with the mounting plate 11 through the positioning block 55 to realize the limiting of the pressure rod 51. The positioning block 55 can prevent the pressure rod 51 from continuing to apply excessive stress after it has clamped the workpiece into place, so as to effectively protect the workpiece. At the same time, it can limit the left and right swaying of the pressure rod 51, prevent the upper clamping block 53 from deviating from the point of action of the workpiece, and improve the positioning accuracy.

[0031] In the clamping unit with positioning detection mechanism provided in this embodiment of the present invention, as a further design improvement, the clamping assembly 5 further includes an operating lever 56, which is mechanically fixed above the other end of the pressure rod 51 for manual intervention. By setting the operating lever 56, manual operation of opening and clamping of the clamping assembly 5 can be achieved. Thus, the clamping unit with positioning detection mechanism provided in this embodiment of the present invention can not only be used in unmanned automated production, but also in non-automated production lines, suitable for small-batch trial production, further improving the versatility and applicability of the present invention.

[0032] In the clamping unit with positioning detection mechanism provided in this embodiment of the utility model, as a further design improvement, the clamping assembly 5 further includes: a first positioning block 57 and a second positioning block 58. Here, the first positioning block 57 and the second positioning block 58 are respectively arranged on the left and right sides of the pressure rod 51 to realize the positioning of the workpiece. When the pressure rod 51 is long or it is necessary to use the positioning points on the workpiece for positioning, the first positioning block 57 and the second positioning block 58 can be added to further improve the positioning accuracy. By setting positioning pins on the first positioning block 57 and the second positioning block 58 and pinning them to the positioning holes of the corresponding parts on the workpiece, accurate and reliable positioning of the workpiece can be achieved.

[0033] Compared with the prior art, the clamping unit with positioning detection mechanism involved in this utility model has a reasonable structural design. By setting the detection component 3 and the sensing component 4, the positioning detection and control of the workpiece clamping state are realized, which improves the adaptability of the clamping unit and realizes accurate control of the clamping force. It can be applied to automated and non-automated production lines, has good adaptability, and provides accurate and reliable positioning and clamping, thus meeting the specific needs of users.
