Detailed Description

For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings and examples. It is to be understood that the examples are illustrative of the invention only and are not limiting.

Example 1

As shown in fig. 1 and fig. 2, the embodiment provides a machine tool casting tapping positioning fixture, which includes a base 110, a first mounting plate 121 and a second mounting plate 122 that are arranged in parallel on the base 110, a screw 130 is threaded through the first mounting plate 121, a connecting rod 140 is fixedly connected to the inner side of the second mounting plate 122, mounting blocks 150 are respectively rotatably connected to the inner ends of the screw 130 and the connecting rod 140, a clamping plate 160 is fixedly connected to the inner end of any mounting block 150, and the clamping plate 160 is in an arc shape.

The screw 130 rotates on the first mounting plate 121, and the screw 130 can be adjusted inside and outside, so that the clamp plate 160 connected with the screw 130 can be adjusted inside and outside, and the other clamp plate 160 is connected to the second mounting plate 122 through the connecting rod 140, so that the casting can be clamped through the adjustment of the screw 130. Because an installation piece 150 rotates with screw rod 130 to be connected, another installation piece 150 rotates with connecting rod 140 to be connected, so, when screw rod 130 rotated, splint 160 can not rotate along with screw rod 130, and splint 160 also can rotate to suitable angle and clip the foundry goods, and like this, splint 160 just can clip the foundry goods in the position of preferred, and the location accuracy is good, and stability is good, and the axiality is higher, and it is high to attack the screw success rate, and moreover, the work piece dismouting is very convenient. The clamping plate 160 is arc-shaped, which enables the clamping plate 160 to better clamp the casting and improve stability.

In this embodiment, a rubber pad 161 is disposed on the inner side of the clamping plate 160.

The rubber pad 161 provides cushioning to prevent the clamp plate 160 from pinching the casting.

In this embodiment, the bottom ends of the first mounting plate 121 and the second mounting plate 122 both extend downward and penetrate through the base 110, a plurality of screw holes 170 are respectively formed on the outer sides of the first mounting plate 121 and the second mounting plate 122, screws 180 are arranged on the side surfaces of the base 110 in a penetrating manner, and the screws 180 are correspondingly matched with the screw holes 170.

The screw 180 can be inserted into the screw holes 170 at different positions, so that the heights of the first mounting plate 121 and the second mounting plate 122 can be adjusted, and thus, the height of the clamping plate 160 can be conveniently adjusted, thereby enabling the positioning of the casting to be more stable.

The plurality of screw holes 170 are divided into two groups, each group of screw holes 170 is vertically arranged, the number of the screws 180 is two, one screw 180 corresponds to one group of screw holes 170, and when one screw 180 is inserted into different screw holes 170, the first mounting plate 121 or the second mounting plate 122 realizes height adjustment.

In this embodiment, a hand wheel 131 is disposed outside the screw 130.

The provision of the handwheel 131 facilitates rotation of the screw 130.

In this embodiment, a circular cavity 151 is formed in the mounting block 150, a rotatable round head 190 is formed in the circular cavity 151, and the round head 190 penetrates out of the circular cavity 151 and then is fixedly connected with the corresponding screw 130 or the corresponding connecting rod 140.

Through the cooperation of the round head 190 and the round cavity 151, the round head 190 can conveniently rotate in the round cavity 151, and therefore, the clamping plate 160 can flexibly rotate on the screw rod 130 or the connecting rod 140.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
