detailed description

The foregoing and other features of the present invention will become apparent from the following description, with reference to the accompanying drawings. In the description and accompanying drawings, specific embodiments of the utility model are specifically disclosed, which shows some implementations in which the principle of the utility model can be adopted. It should be understood that the utility model is not limited to the described embodiments, but rather It is intended to include all modifications and equivalents falling within the scope of the appended claims.

In the following description of the present utility model, for the convenience of explanation, the direction parallel to the clamping rod is defined as the "up and down direction", wherein, the direction that the clamping rod points to the clamping seat is the "downward direction", which is the same as the "downward direction". The direction opposite to "direction" is "upward direction".

The embodiments of the present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.

Embodiment one

This embodiment provides an adjustable copper male fixture, please refer to Figure 1, the utility model embodiment provides an adjustable copper male fixture, including:

The fixing block 10, whose specific structure is not limited, is fixed on the main shaft of the electric discharge machine tool, and is mainly used to provide a good fixing function for the clamping rod 11 .

The clamping rod 11 is fixedly assembled on the lower end of the fixed block 10 for connecting and fixing the clamping seat 12 .

Wherein, the clamping seat 12 is provided with fastening screws 13 for fixing the copper male 14 .

Each institution is described in detail below:

Please refer to FIG. 2 , in this embodiment, two adjustment openings 121 are opened on the clamping base 12 . In order to maintain the stability of the device, the clamping rod 11 is installed at the center of the clamping base 12, and two adjustment openings 121 are arranged oppositely on both sides of the clamping rod 12, and the two adjustment openings 121 are located on the same straight line.

Wherein, the adjusting opening 121 is provided with fastening screws 13 , preferably, in order to save cost and ensure the balance of the copper male 14 , two fastening screws 13 are provided.

Since the main function of the adjustment opening 121 is to flexibly adjust the position of the fastening screw 13 , the fastening screw 13 needs to be able to move relative to the clamping seat 12 . In order to meet the aforementioned requirements, the head of the fastening screw 13 is clamped at the upper opening of the adjustment opening 121, and the diameter of the tail of the fastening screw 13 is smaller than the width of the adjustment opening 121, so that the fastening screw 13 can be adjusted in the adjustment opening 121. The center moves along the adjustment opening 121 , so that the fastening screw 13 is movably connected with the clamping seat 12 .

In this embodiment, by moving the fastening screws 13 in the adjustment opening 121, the distance between the fastening screws 13 matches the width of the clamped copper male 14, and then the lower ends of the fastening screws 13 are screwed into the copper male 14 Screw holes on the top, to achieve the purpose of clamping the copper male 14.

Please refer to Fig. 3, in order to facilitate the installation of the fastening screw 13, based on the above features of this embodiment, another implementation of this embodiment is:

Openings are provided at opposite ends of the two adjustment openings 121 , through which fastening screws 13 can be inserted into the adjustment openings 121 .

Embodiment two

In the above-mentioned embodiment of the utility model, since the clamping rod 11 is installed in the center of the clamping seat 12, the two adjustment openings are oppositely arranged on both sides of the clamping rod 12, when the width of the copper male 14 is less than or When equal to the diameter of clamping rod 11, this device is not applicable.

For this reason, this embodiment two has carried out the following improvement on the basis of embodiment one:

Referring to FIG. 4 , one adjustment opening 121 is provided, and two clamping rods 11 are provided. In order to ensure the stability of the device, two clamping rods 11 are respectively installed on both sides of the adjustment opening 121 .

In this embodiment, since the clamping rod 11 is arranged as two pieces on both sides of the adjustment opening 121, which can accommodate the copper male 14 whose width is less than or equal to the diameter of the clamping rod 11, it is more advantageous than the first embodiment. .

Embodiment three:

When the size and weight of the copper male 14 are relatively large, the implementation methods of the first and second embodiments above cannot reduce the stress on the copper male 14, which may easily damage the copper male 14. Therefore, the present embodiment three has carried out the following improvements on the basis of embodiment one and embodiment two:

Please refer to FIG. 5 , in this embodiment, two adjustment openings 121 are arranged in parallel, and the two adjustment openings 121 are installed on both sides of the clamping rod 11 respectively. Wherein, the two adjustment openings 121 are located on different straight lines. Each adjustment opening 121 is provided with a fastening screw 13 , and the heads of the two fastening screws 13 are respectively clamped at the upper opening of the adjustment opening 121 and can move in the adjustment opening 121 .

Based on the improvement of this embodiment, when the copper male 14 is relatively large, or the length and width of the cross-section of the copper male 14 are not much different, the two fastening screws 13 can be adjusted by adjusting the positions of the two fastening screws 13. Located on the diagonal of the copper male 14, then the fastening screw 13 is screwed into the screw hole on the copper male 14, so that the fastening screw 13 and the copper male 14 are threaded, so that the copper male 14 is clamped and fixed.

Since the fastening screw 13 is fixed on the opposite corner of the copper male 14, even when the size and weight of the copper male 14 are large, the design of this embodiment can also balance the force of the copper male 14, thereby prolonging the use of the copper male 14 life.

Embodiment four:

In the above-mentioned embodiment, since the fastening screw 13 can freely slide in the adjustment opening 121, when the fastening screw 13 is fixed to the copper male 14, the copper male 14 will slide along the direction of the adjustment opening 121, which is not conducive to the electrical adjustment. The work of the spark machine.

In order to solve the above defects, the fourth embodiment makes the following improvements based on the above embodiments:

An anti-slip pad is provided on the edge of the adjustment opening 121 on the clamping seat 12 , or an elastic positioning block is provided in the adjustment opening 121 to increase the friction between the fastening screw 13 and the clamping seat 12 .

In this embodiment, the relative movement between the copper pin 14 and the clamping base 12 is controlled by controlling the relative movement between the fastening screw 13 and the clamping base 12, thereby ensuring the stability of the device.
