Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a metal product processing clamp. Background Art

[0002] Metal processing is a way of manufacturing modern objects. During processing, it is generally necessary to clamp and fix the metal parts to be processed by fixtures to avoid errors in processing accuracy or personal injuries caused by movement of the workpiece.

[0003] The existing Chinese patent application number: 202321336344.0 discloses a metal product processing fixture, including a bottom plate and a base. The top of the base is provided with an extrusion rod, a turntable is welded to the top of the extrusion rod, a sphere is provided at the bottom of the extrusion rod, the top of the sphere is fixedly connected to a threaded rod, the threaded rod is installed at the bottom of the extrusion rod, and an extrusion plate is welded to the bottom of the threaded rod.

[0004] When the clamp proposed by the above technology is in use, a base is set at both ends of the bottom plate, and four extrusion rods are set at the upper end of the base. Threaded rods are set at the ends of the four extrusion rods, which to a certain extent achieves the effect of clamping metal parts of different shapes. However, in actual use, it is time-consuming and labor-intensive to manually rotate the eight extrusion rods, and when replacing the sphere or the extrusion plate, the eight extrusion rods need to be twisted. As a result, the efficiency of personnel is low when performing large-scale metal processing production. Therefore, in order to solve the above technical problems, we propose a metal product processing clamp. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a metal product processing fixture.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Preferably, a placement groove is provided at the upper end of the mounting block and a magnetic sheet is provided on the bottom surface of the placement groove, and the lower end of the lower clamping head is adsorbed in the placement groove through the magnetic sheet.

[0013] Preferably, the pitch adjustment assembly includes left and right screw rods and a handwheel.

The middle parts of the two mounting frames are respectively connected to the two ends of the left and right screw rods through sliders, and the handwheels are installed at the two end ends of the left and right screw rods.

[0014] The utility model provides a metal product processing fixture, which has the following beneficial effects:

[0015] 1: In the utility model, the eight squeezing rods in the traditional scheme are replaced by the setting of the telescopic cylinder. That is, when the present scheme is used, the personnel only need to control the operation of the telescopic cylinder through the external operation button to clamp the workpiece quickly and firmly; at the same time, when the corresponding clamping head needs to be replaced, the upper clamping head or the lower clamping head is directly held and force is applied to it until the upper clamping head or the lower clamping head is pulled out from the linkage plate or the mounting block, and the personnel further re-adsorbs the new upper clamping head and the lower clamping head into the linkage plate or the mounting block through the cooperation of the magnetic suction block and the magnetic suction sheet, that is, the replacement process of the clamping head is completed at this time, that is, compared with the traditional scheme, when clamping the workpiece, the present scheme can clamp the workpiece quickly, and when replacing the contact part for clamping the workpiece, the present scheme can be directly pulled out, which effectively avoids the phenomenon that the eight threaded rods need to be rotated in sequence in the traditional scheme, thereby making the present scheme time-saving and labor-saving when used.

[0016] 2: The rectangular placement groove and the accommodating groove in the utility model are arranged to limit the upper clamping head and the lower clamping head, that is, to avoid the phenomenon that the two clamping heads rotate arbitrarily and cannot clamp the metal parts quickly and accurately, and because there are gaps between the magnetic block and the upper clamping head and between the magnetic sheet and the lower clamping head, the phenomenon that the magnetic block and the magnetic sheet are crushed can be avoided; the arrangement of the support frame makes the support frame not only limited and fixed by the upper mounting frame, but also supported by the support frame at the lower end, which improves the stability of the support frame during use; the arrangement of the distance adjustment component makes it easy to move the two mounting frames, so that the present scheme can be adapted to the length of the metal parts to be processed.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Example 1

[0026] Reference Figure 1-6 A metal product processing fixture includes a mounting base 1, the front side of the mounting base 1 is connected to two mounting frames 2 through a distance adjustment component, the front sides of the mounting frames 2 are each installed with a telescopic cylinder 3, the lower end of the telescopic cylinder 3 is installed with an upper clamping head 5 through a magnetic block 4, and the lower side of the mounting frames 2 is fixed with a supporting frame 6, the lower end of the supporting frame 6 is located below the upper clamping head 5 and is fixed with a mounting block 7, and the upper end of the mounting block 7 is inserted with a matching lower clamping head 8 corresponding to the upper clamping head 5.

[0027] Example 2

[0028] Reference Figure 1-6 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0029] A placement groove is provided at the upper end of the mounting block 7 and a magnetic sheet 9 is provided on the bottom surface of the placement groove. The lower end of the lower clamping head 8 is adsorbed in the placement groove through the magnetic sheet 9. The setting of the magnetic sheet 9 can keep the lower clamping head 8 and the mounting block 7 stable; there is a 0.2MM gap between the magnetic sheet 9 and the lower surface of the lower clamping head 8, the placement groove is rectangular, a linkage plate 10 is fixed to the output end of the telescopic cylinder 3, and a receiving groove is provided on the lower surface of the linkage plate 10. The magnetic block 4 is installed inside the receiving groove, and the upper end of the upper clamping head 5 is adsorbed in the placement groove through the magnetic sheet 9. The block 4 is adsorbed in the receiving groove. The rectangular placement groove and the receiving groove are set to facilitate the limiting of the upper clamping head 5 and the lower clamping head 8, that is, to avoid the two clamping heads from rotating at will, resulting in the inability to quickly and accurately clamp the metal parts. In addition, since there is a gap between the magnetic block 4 and the upper clamping head 5 and between the magnetic sheet 9 and the lower clamping head 8, the magnetic block 4 and the magnetic sheet 9 can be avoided from being crushed; there is a 0.2MM gap between the magnetic block 4 and the upper surface of the upper clamping head 5, and the receiving groove is rectangular.

[0030] A support frame 11 is fixed to both ends of the mounting seat 1, and the inner bottom surface of the support frame 11 is in contact with the lower surface of the support frame 6. The setting of the support frame 11 makes the support frame 6 not only limited and fixed by the upper mounting frame 2, but also supported by the support frame 11 at its lower end, which improves the stability of the support frame 6 when in use; the force-bearing distance-adjusting component includes left and right screw rods 12 and a handwheel 13. The left and right screw rods 12 are mounted on the front side of the mounting seat 1 through bearings and bearing seats. The middle parts of the two mounting frames 2 are connected to the two ends of the left and right screw rods 12 through sliders 14 respectively, and the handwheel 13 is installed at the two end ends of the left and right screw rods 12. The setting of the distance-adjusting component facilitates the movement of the two mounting frames 2, thereby facilitating the adaptation of the present scheme to the length of the metal parts to be processed.

[0031] Principle and advantages of use: During the use of the utility model, since the support frame 6 and the mounting frame 2 are fixedly connected, that is, when processing metal parts, the personnel first lift the upper clamping head 5 upwards through the telescopic cylinder 3, so that there is a larger gap between the upper clamping head 5 and the lower clamping head 8, and then the personnel place the two ends of the metal part to be processed between the two upper clamping heads 5 and the lower clamping head 8. At this time, the personnel pushes the upper clamping head 5 downward through the telescopic cylinder 3, and finally the workpiece is firmly clamped between the upper clamping head 5 and the lower clamping head 8. Therefore, the setting of the telescopic cylinder 3 replaces the eight extrusion rods in the traditional scheme, that is, when this scheme is used, the personnel only needs to control the operation of the telescopic cylinder 3 through external operation buttons to quickly and firmly clamp the workpiece.

[0032] At the same time, when processing workpieces of different shapes, if the corresponding clamping head needs to be replaced, the upper clamping head 5 and the lower clamping head 8 are first controlled to separate by the telescopic cylinder 3, and then the personnel directly hold the upper clamping head 5 or the lower clamping head 8 and apply force to it until the upper clamping head 5 or the lower clamping head 8 is pulled out of the linkage plate 10 or the mounting block 7. Further, the personnel re-adsorb the new upper clamping head 5 and the lower clamping head 8 into the linkage plate 10 or the mounting block 7 through the cooperation of the magnetic block 4 and the magnetic sheet 9. At this time, the replacement process of the clamping head is completed.

[0033] It should be further explained that the upper clamping head 5 and the lower clamping head 8 can be set in several groups according to the shape of the metal parts to be processed, such as common cylindrical parts, angle irons, square tubes, plates, etc. The specific shape of the clamping head is not described in detail in this scheme. It is only necessary to replace the clamping head of the corresponding shape according to the shape of the workpiece during processing. The telescopic cylinder 3 is a common part with a telescopic effect, such as an electric cylinder, a hydraulic cylinder, a pneumatic cylinder, etc., which is no longer described in detail in this scheme. When using it, the corresponding electric cylinder, pneumatic cylinder or hydraulic cylinder can be selected according to its own economy and processing needs; the setting of the rectangular placement groove and the accommodating groove is convenient for the upper clamping head 5 and the lower clamping head to be aligned. The holding head 8 is limited, that is, the two clamping heads are prevented from rotating at will, which makes it impossible to clamp the metal parts quickly and accurately. In addition, since there is a gap between the magnetic block 4 and the upper clamping head 5 and between the magnetic sheet 9 and the lower clamping head 8, the magnetic block 4 and the magnetic sheet 9 can be prevented from being crushed. The setting of the support frame 11 makes the support frame 6 not only limited and fixed by the upper mounting frame 2, but also supported by the support frame 11 at the lower end, which improves the stability of the support frame 6 during use. The setting of the distance adjustment component facilitates the movement of the two mounting frames 2, so that the present scheme can be adapted to the length of the metal parts to be processed.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
