Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a clamping tooling with adjustable pressing position. Background Art

[0002] The shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determine the quality of these products. Due to the different materials, appearances, specifications and uses of various products, molds are divided into non-plastic molds such as casting molds, forging molds, die-casting molds, stamping molds, and plastic molds. The ejector plate and ejector fixing plate are important components of the mold and are also part of the early mold base. The ejector plate or ejector fixing plate needs to be drilled on the side wall. At present, the ejector plate is placed against the side wall of the workbench of the drilling machine and then clamped with an F clamp. However, since the F clamp is basically stuck and does not move, the position of the ejector plate or ejector fixing plate needs to be adjusted in time. Different sizes of specifications still need to move the F clamp to avoid not being able to clamp on both sides. If the position is not pressed well, it is necessary to move the ejector plate to adapt to the screw on the F clamp, but the heavy ejector plate is not only difficult to move, but also easy to collide with the F clamp during the movement, causing damage. Summary of the invention

[0003] In view of this, the purpose of the utility model is to overcome the deficiencies in the prior art and provide a clamping tool with an adjustable clamping position.

[0004] The utility model provides a clamping tool with adjustable clamping position, which is installed on a workbench 1 and includes guide rods 2 that are symmetrically arranged on the left and right. The guide rods 2 are clamped in the T-slots at the upper end of the workbench 1. The guide rods 2 are slidably provided with movable arms 3. The lower sides of the front ends of the two movable arms 3 are horizontally provided with connecting rods 4. The connecting rods 4 are slidably provided with sliders 5 that can move left and right. The upper and lower ends of the sliders 5 are longitudinally screwed with screws 6.

[0005] Furthermore, the movable arm 3 is composed of an upper inclined section connected to a lower extending section, and the inclined section is slidably fitted on the guide rod 2 .

[0006] Furthermore, adjustment holes 4.1 are symmetrically and transversely opened on the left and right sides of the connecting rod 4, and the connecting rod 4 is locked to the moving arm 3 by a locking bolt passing through the adjusting hole 4.1.

[0007] Furthermore, the two screw rods 6 are vertically symmetrical along the cross section of the connecting rod 4 .

[0008] Furthermore, a pressure plate is provided at the end of the screw rod 6 , and a rotating rod 7 is passed through the front end of the screw rod 6 .

[0009] The utility model has the advantages that: the clamping position can be adjusted by moving the slider left and right without moving the ejector plate or the ejector fixing plate, and the operation is convenient and reliable; the appropriate clamping position can be selected by moving the slider left and right; the movable arm is composed of an upper inclined section connected to a lower extension section; when the guide rod is moved left and right, the left and right position of the connecting rod can be adjusted to adapt to the change of the guide rod; the screw rod is symmetrically arranged up and down, and the force can be balancedly fed back to the connecting rod to prevent the connecting rod and the slider from deforming.

[0014] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0015] See also Figures 1 to 4 The utility model provides a clamping tool with adjustable clamping position, which is installed on a workbench 1, and includes a guide rod 2 symmetrically arranged on the left and right, the guide rod 2 is clamped in a T-shaped slot at the upper end of the workbench 1, and a movable arm 3 is provided on the guide rod 2. The movable arm is a modification of the existing F clamp, and a connecting rod 4 is horizontally arranged on the lower side of the front end of the two movable arms 3, and a slider 5 is provided at the connecting rod 4 for sliding movement to the left and right. The appropriate clamping position is selected by the slider moving to the left and right, and the upper and lower ends of the slider 5 are longitudinally screwed with a screw 6, and a pressure plate is arranged at the end of the screw 6, and a rotating rod 7 is penetrated at the front end of the screw 6. The ejector plate or ejector fixing plate can be lowered from between the two guide rods without timely adjusting the position, and the ejector plate or ejector fixing plate of different sizes is applicable, leaning against the side wall of the workbench and padded with a pad, moving the slider to the left and right to the appropriate position, rotating the screw through the rotating rod, so that the screw moves backward to press the ejector plate or ejector fixing plate, and the drilling machine will drill a hole on the upper end surface of the ejector plate or ejector fixing plate.

[0016] The movable arm 3 is composed of an upper inclined section connected to a lower extending section, and the inclined section is slidably fitted on the guide rod 2 .

[0017] See also Figure 1 , Figure 2The connecting rod 4 has adjustment holes 4.1 symmetrically and transversely opened on the left and right sides. The connecting rod 4 is locked to the moving arm 3 by a locking bolt passing through the adjustment hole 4.1. When the guide rod is moved left and right, the left and right position of the connecting rod can be adjusted by loosening the locking bolt, and then the locking bolt is tightened to lock the connecting rod to adapt to the change of the guide rod.

[0018] The two screw rods 6 are symmetrical up and down along the cross section of the connecting rod 4. The symmetrical arrangement of the screw rods up and down can feedback the force to the connecting rod in a balanced manner to prevent the connecting rod and the slider from deforming.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
