Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0017] Specific implementation case:

[0018] For example, Figure 1As shown, a kind of anti-deviation clamp for fixing seat machining, including bottom plate 1, the clamping plate 2 is installed at the center of the bottom plate 1, the lateral positioning mechanism 3 is slidably installed on the bottom plate 1, the lateral positioning mechanism 3 is installed on the both sides of clamping plate 2, the lateral positioning mechanism 3 is symmetrically provided with two groups with the clamping plate 2 as center, the pressure holding mechanism 5 is slidably installed on the bottom plate 1, the pressure holding mechanism 5 is installed on the top side of clamping plate 2;

[0019] The anti-deviation clamp in working, first operator will be fixed seat along clamping plate 2 and enter two lateral positioning mechanisms 3, the position correction and preliminary clamping positioning of fixed seat side edge are carried out, continue to advance fixed seat top end into pressure holding mechanism 5, the position correction and preliminary clamping positioning of fixed seat top end side edge are carried out, then after position correction, operator again with bolt and nut will be fixed seat fixed on clamping plate 2, then carry out processing, the combination of lateral positioning mechanism 3 and pressure holding mechanism 5 is self-adapting anti-deviation mechanism, and the fixed seat of different sizes can be prevented from deviating and positioned, and lateral positioning mechanism 3 and pressure holding mechanism 5 still maintain a working state when processing, so that fixed seat is still in side edge positioning and pressure holding state when processing.

[0020] Lateral positioning mechanism 3 includes fixed plate 31, the fixed plate 31 is fixedly connected with bottom plate 1, two groups of telescopic rods 321 are symmetrically installed on the fixed plate 31, first spring 32 is installed outside telescopic rod 321, the first spring 32 is fixedly connected with fixed plate 31, push plate 33 is slidably installed on telescopic rod 321, the push plate 33 is fixedly connected with first spring 32, longitudinal positioning mechanism 4 is installed on push plate 33, transmission block 6 is slidably installed on push plate 33, and transmission block 6 is installed below longitudinal positioning mechanism 4;

[0021] Pressure holding mechanism 5 includes middle end pressure holding block 51, the middle end pressure holding block 51 is fixedly connected with longitudinal positioning mechanism 4, and the middle end pressure holding block 51 is slidably connected with push plate 33;

[0022] Longitudinal positioning mechanism 4 includes connecting frame 41, the connecting frame 41 is fixedly connected with push plate 33, transmission rod 42 is slidably installed on the connecting frame 41, second spring 43 is arranged on transmission rod 42, the second spring 43 is fixedly connected with connecting frame 41, the second spring 43 is fixedly connected with push plate 33, and lateral pressure holding block 44 is installed below transmission rod 42;

[0023] Second spring 43 is installed at the connection of transmission block 6 and push plate 33;

[0024] Downwardly open slope (not marked in the figure) is arranged on the lateral pressure holding block 44, outwardly open slope is arranged on transmission block 6, and downwardly open slope is arranged on the front surface of middle end pressure holding block 51.

[0025] When the operator pushes the fixed seat along the clamping plate 2 into the two lateral positioning mechanisms 3, the top edge of the fixed seat first contacts the downwardly open slope on the lateral pressing block 44, and in the process of continuous pushing, the lateral pressing block 44 is pushed upward along the transmission rod 42, and the second spring 43 is compressed. At the same time, the side edge of the fixed shaft contacts the outwardly open slope on the transmission block 6, and in the process of continuous pushing, the transmission block 6 is pushed into the push plate 33, and the second spring 43 installed therein is compressed. Until the bottom surface of the lateral pressing block 44 contacts the top surface of the fixed seat, the side surface of the transmission block 6 contacts the side surface of the fixed seat, and the second spring 43 provides clamping force for clamping. The working principle of the lateral positioning mechanism 3 on the other side of the clamping plate 2 is the same as described above, and will not be described again. This process completes the clamping and positioning of the side edges of the fixed seat by the lateral positioning mechanism 3.

[0026] After the clamping of the lateral positioning mechanism 3 is completed, the fixed block continues to push, and the top edge contacts the downwardly open slope on the middle-end pressing block 51. In the process of continuous pushing, the middle-end pressing block 51 is pushed upward along the transmission rod 42, and the second spring 43 is compressed. Until the lower end of the middle-end pressing block 51 contacts the upper end surface of the fixed seat, and finally the front side surface of the fixed seat contacts the front end surface of the push plate 33 on the pressing mechanism 5. The mutual clamping and positioning of the lateral positioning mechanism 3 and the pressing mechanism 5 fix the position of the fixed seat. Then, the operator uses the clamping method of the universal clamp to clamp the fixed seat. During machining, the anti-deviation mechanism still acts on the fixed seat, so that the position of the fixed seat is not affected by machining.

[0027] In summary, by pushing the fixed seat into the two lateral positioning mechanisms 3 by the operator, the top edge of the fixed seat first contacts the downwardly open slope on the lateral pressing block 44, and until the bottom surface of the lateral pressing block 44 contacts the top surface of the fixed seat. At the same time, the side edge of the fixed shaft contacts the outwardly open slope on the transmission block 6, and until the side surface of the transmission block 6 contacts the side surface of the fixed seat. The other side of the lateral positioning mechanism 3 has already performed this work. After the clamping of the lateral positioning mechanism 3 is completed, the fixed block continues to push, and the top edge contacts the downwardly open slope on the middle-end pressing block 51. Until the lower end of the middle-end pressing block 51 contacts the upper end surface of the fixed seat, and finally the front side surface of the fixed seat contacts the front end surface of the push plate 33 on the pressing mechanism 5. The mutual clamping and positioning of the lateral positioning mechanism 3 and the pressing mechanism 5 realize the cooperation of the universal clamp during machining, so that the position of the fixed seat is not affected by machining.
