Description

Technical Field

[0001] The present application relates to the technical field of clamping tooling, and in particular to a continuous clamp. Background Art

[0002] A fixture usually consists of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, a tool guiding element (to determine the relative position of the tool and the workpiece or to guide the direction of the tool), an indexing device (to enable the workpiece to complete processing at several stations in one installation, which includes a rotary indexing device and a linear indexing device), a connecting element, and a clamping base (fixture base).

[0003] During the perforation process of the workpiece, in order to prevent the workpiece from shifting due to external force, it is generally necessary to fix the workpiece with a clamp. The existing workpiece cannot be punched at the clamping position after clamping, which makes the existing clamp very inconvenient to use. Utility Model Content

[0004] The utility model aims to solve or at least alleviate the problem that after the existing workpiece is clamped and fixed by the clamp, it is impossible to punch holes at the clamping position due to the shielding effect of the clamp, which makes the existing clamp very inconvenient to use.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A continuous clamp comprises a support plate with supporting and fixing functions, a first clamping assembly and a second clamping assembly are arranged above the support plate, the first clamping assembly comprises a plurality of first perforated seats fixedly connected to the upper surface of the middle section of the support plate, a workpiece to be perforated is placed on the top of the first perforated seat, a first cylinder is fixedly connected to the support plates on both sides of the first perforated seat, a first piston rod is installed on the top of the first cylinder, a first clamping plate arranged horizontally is fixedly connected to the end of the first piston rod away from the first cylinder, the second clamping assembly comprises second perforated seats fixedly connected to the two ends of the support plate, a second cylinder is fixedly connected to the support plate on the rear side of the second perforated seat, a second piston rod is installed on the top of the second cylinder, and a second clamping plate is fixedly connected to the end of the second piston rod away from the second cylinder.

[0007] By adopting the above technical solution, when using it, the user first places the workpiece to be punched on the top of the first punch seat, and starts the first cylinders on both sides of the first punch seat, and drives the first piston rod to contract through the first cylinder, thereby driving the first clamping plate to move downward, and utilizes the first clamping plates on both sides to cooperate with the first punch seat below to clamp the two ends of the workpiece, and then the middle section of the workpiece can be punched. When the middle section of the workpiece is punched, the workpiece can be removed from the first punch seat, and the workpiece can be turned over and placed on the second punch seat. At this time, the second cylinder is started to drive the second piston rod to contract, thereby causing the second clamping plate to move down and cooperate with the second punch seat to clamp the middle part of the workpiece, and then holes can be punched at both ends of the workpiece, which avoids the problem that the existing workpiece cannot be punched at the clamping position due to the blocking effect of the clamp after being clamped and fixed by the clamp, resulting in the existing clamp being very inconvenient to use.

[0008] Optionally, the connection places between the first cylinder and the second cylinder and the support plate are fixedly connected with a mounting seat, and bolts are passed through the circumference of the mounting seat. The bolts penetrate the mounting seat and are screwed to the support plate.

[0009] By adopting the above technical solution, a mounting seat is provided to improve the stability of the installation of the first cylinder and the second cylinder, and a bolted connection method is adopted, which not only ensures a stable connection, but also facilitates the user to install and disassemble the first cylinder and the second cylinder.

[0010] Optionally, the center of the upper surface of the workpiece protrudes upward to form a protrusion, and a positioning groove corresponding to the protrusion is opened at the center of the top end of the second perforated seat.

[0011] By adopting the above technical solution, when it is necessary to perforate both ends of the workpiece, the workpiece can be turned over and the protrusion formed on the workpiece can be embedded in the positioning groove opened at the top of the second perforating seat to achieve positioning of the workpiece and facilitate perforation of the workpiece.

[0012] Optionally, the tops of the first perforating seat and the second perforating seat are both provided with alignment holes corresponding to the perforating positions of the workpiece, and the inner diameter of the alignment holes is larger than the diameter of the holes to be perforated on the workpiece.

[0013] By adopting the above technical solution, a positioning hole with a hole diameter larger than the inner diameter of the workpiece hole is set so that the external punching tool can be accommodated in the positioning hole after penetrating the workpiece, thereby preventing the external punching tool from causing damage to the first punching seat and the second punching seat after punching.

[0014] Optionally, rubber pads for improving clamping stability are bonded to the lower surfaces at both ends of the first clamping plate and the lower surface of a section of the second clamping plate located above the second perforated seat.

[0015] By adopting the above technical solution, the rubber pad is provided to improve the clamping stability, and at the same time, the first clamping plate and the second clamping plate can be prevented from being hard squeezed with the workpiece during the clamping process, resulting in deformation and damage of the workpiece.

[0016] Optionally, two guide plates are symmetrically arranged at the bottom of the rubber pad installed on the lower surface of the first clamping plate, and a slope is provided on the side of the guide plate away from the first piston rod. The distance between the top ends of the two guide plates installed on two adjacent first piston rods is equal to the length of the workpiece.

[0017] By adopting the above technical solution, when the first clamping plate moves downward under the traction of the first piston rod, the inclined surface of the guide plate can push the workpiece to move, thereby guiding and positioning the workpiece.

[0018] Optionally, the second perforated seat extends outward from one side close to the second piston rod to form a joint, and the joint is sleeved on the top of the second piston rod and welded to the top end of the second piston rod.

[0019] By adopting the above technical solution, a joint is provided to fix the second clamping plate on the top end of the second piston rod through the joint, so that the second clamping plate can be driven to move up and down when the second piston rod is extended or retracted, thereby achieving the clamping of the workpiece.

[0020] In summary, the beneficial effects of this application are as follows:

[0021] The present application cooperates with the first punching seat, the first clamping plate, the second punching seat and the second clamping plate to allow the user to place the workpiece on the first punching seat when punching the middle section of the workpiece, and use the first clamping plate to clamp and fix the two ends of the workpiece. When it is necessary to punch holes at both ends of the workpiece, the workpiece can be removed and placed on the second punching seat, and the middle section of the workpiece can be punched using the second clamping plate and the second punching seat, thereby avoiding as much as possible the problem that after the workpiece is clamped and fixed by the clamp, the clamping position cannot be punched due to the obstruction of the clamp, which makes the use of the existing clamp very inconvenient.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] See also Figure 1-3 The continuous clamp includes a support plate 1 with supporting and fixing functions. A first clamping assembly and a second clamping assembly are arranged above the support plate 1. The first clamping assembly and the second clamping assembly are respectively used to clamp different positions of the product that needs to be perforated, and cooperate with each other to facilitate the perforation work on various parts of the product.

[0028] The first clamping assembly includes a plurality of first perforating seats 2 fixedly connected to the upper surface of the middle section of the support plate 1 , and the workpiece 3 to be perforated is placed on the top of the first perforating seat 2 .

[0029] The support plates 1 on both sides of the first perforating seat 2 are fixedly connected with the first cylinder 5, and the top of the first cylinder 5 is installed with a first piston rod 6. The end of the first piston rod 6 away from the first cylinder 5 is fixedly connected with a horizontally arranged first clamping plate 7. When it is necessary to perforate the middle section of the workpiece 3, the first cylinders 5 on both sides of the first perforating seat 2 can be started, and the first piston rod 6 can be driven to contract by the first cylinder 5, thereby driving the first clamping plate 7 to move downward. The first clamping plates 7 on both sides are used to cooperate with the first perforating seat 2 below to clamp the two ends of the workpiece 3, so as to facilitate the perforation of the middle section of the workpiece 3.

[0030] The second clamping assembly includes a second perforating seat 10 fixedly connected to both ends of the support plate 1. When the middle section of the workpiece 3 is perforated, the user can remove the workpiece 3 from the first perforating seat 2, flip the workpiece 3, and place the workpiece 3 on the second perforating seat 10.

[0031] A second cylinder 13 is fixedly connected to the support plate 1 at the rear side of the second perforating seat 10, a second piston rod 14 is installed at the top of the second cylinder 13, and a second clamping plate 15 corresponding to the middle position of the second perforating seat 10 is fixedly connected to the end of the second piston rod 14 away from the second cylinder 13. The user can start the second cylinder 13 to drive the second piston rod 14 to contract, so that the second clamping plate 15 moves down to cooperate with the second perforating seat 10 to clamp the middle part of the workpiece 3, so as to facilitate the perforation of both ends of the workpiece 3.

[0032] Reference Figure 1The connection between the first cylinder 5 and the second cylinder 13 and the support plate 1 is fixedly connected with a mounting seat, and bolts are provided on the periphery of the mounting seat, and the bolts penetrate the mounting seat and are screwed to the support plate 1. The mounting seat is provided to improve the stability of the installation of the first cylinder 5 and the second cylinder 13. The bolted connection is not only stable, but also convenient for users to install and remove the first cylinder 5 and the second cylinder 13.

[0033] Reference Figure 1 The center of the upper surface of the workpiece 3 protrudes upward to form a protrusion 4, and a positioning groove 11 corresponding to the protrusion 4 is provided at the center of the top of the second perforating seat 10. When it is necessary to perforate both ends of the workpiece 3, the workpiece 3 can be turned over, and the protrusion 4 formed on the workpiece 3 can be embedded in the positioning groove 11 provided at the top of the second perforating seat 10 to achieve positioning of the workpiece 3, which is convenient for perforating the workpiece 3.

[0034] Reference Figure 1 The first punching seat 2 and the second punching seat 10 are both provided with alignment holes 12 corresponding to the punching positions of the workpiece 3, and the inner diameter of the alignment hole 12 is larger than the hole diameter to be punched on the workpiece 3. The alignment hole 12 having a hole diameter larger than the inner diameter of the workpiece punching hole is provided so that the external punching tool can be accommodated in the alignment hole 12 after penetrating the workpiece 3, thereby preventing the external punching tool from causing damage to the first punching seat 2 and the second punching seat 10 after punching.

[0035] Reference Figure 2 and Figure 3 The lower surfaces of both ends of the first clamping plate 7 and the lower surface of a section of the second clamping plate 15 above the second perforated seat 10 are both bonded with rubber pads 8 for improving the clamping stability. The rubber pads 8 are provided to improve the clamping stability and can avoid the first clamping plate 7 and the second clamping plate 15 from being rigidly squeezed with the workpiece 3 during the clamping process, thereby causing the workpiece 3 to be deformed and damaged.

[0036] Reference Figure 2 The rubber pad 8 installed on the lower surface of the first clamping plate 7 has two guide plates 9 symmetrically arranged at the bottom, and a slope is arranged on the side of the guide plate 9 away from the first piston rod 6, and the distance between the top ends of the two guide plates 9 installed on two adjacent first piston rods 6 is equal to the length of the workpiece 3. When the first clamping plate 7 moves downward under the traction of the first piston rod 6, the slope of the guide plate 9 can push the workpiece 3 to move, so as to guide and position the workpiece 3.

[0037] Reference Figure 3The second perforated seat 10 extends outward from one side close to the second piston rod 14 to form a joint 16, which is sleeved on the top of the second piston rod 14 and welded to the top of the second piston rod 14. The joint 16 is used to fix the second clamping plate 15 on the top of the second piston rod 14 through the joint 16, so that the second clamping plate 15 can be driven to move up and down when the second piston rod 14 is extended and retracted, thereby clamping the workpiece 3.

[0038] The implementation principle of the present application is as follows: when in use, the user first places the workpiece 3 to be perforated on the top of the first perforated seat 2, and starts the first cylinders 5 on both sides of the first perforated seat 2, and drives the first piston rod 6 to contract through the first cylinder 5, thereby driving the first clamping plate 7 to move downward, and uses the first clamping plates 7 on both sides to cooperate with the first perforated seat 2 below to clamp the two ends of the workpiece 3. At this time, the middle section of the workpiece 3 can be perforated. When the middle section of the workpiece 3 is perforated, the workpiece 3 can be removed from the first perforated seat 2, and the workpiece 3 can be turned over and placed on the second perforated seat 10. At this time, the second cylinder 13 is started to drive the second piston rod 14 to contract, so that the second clamping plate 15 moves down and cooperates with the second perforated seat 10 to clamp the middle part of the workpiece 3, so that the two ends of the workpiece 3 can be perforated, and the problem of the existing workpiece 3 being unable to punch the clamping position after being clamped and fixed by the clamp is avoided as much as possible.
