[0002] A thrust rod seat needs to mill one end face and drill five holes on the end face. The conventional clamping method is that in addition to the vertical support and clamping, the horizontal constraint is usually set with the two non-parallel side faces as the reference to set the limit plate, and then set the corresponding extrusion plate to fix the thrust rod seat. This method is generally suitable for a thrust rod seat of one specification. If the specification of the thrust rod seat changes, it is necessary to redesign and manufacture the fixture, or reset the installation reference when installing the fixture on the machine tool, which is troublesome.

[0005] Preferably, the distance between the top of the support plate and the top of the clamping plate is less than the thickness of the thrust rod seat, so that the upper surface of the thrust rod seat after clamping is higher than the clamping plate, avoiding interference during the processing of the upper surface.

[0006] Preferably, the two long screws are fixedly connected to the vertical plate via nuts welded to the vertical plate.

[0007] Preferably, after the thrust rod seat is clamped, the pressure head is coaxial with the guide rod.

[0008] Preferably, a round steel pad is provided between the movable plate and the side surface of the support plate.

[0009] The beneficial effects of the utility model are as follows: a thrust rod seat adaptable clamp, which includes a bottom plate, a vertical plate and two support plates perpendicular to the vertical plate are fixed to the bottom plate, the vertical plate is slidably connected to a card plate through two guide rods, the card plate is in a "〔" shape, a screw rod penetrating the card plate and the vertical plate is arranged between the card plate and the vertical plate, the screw rod is sleeved with a spring whose two ends abut against the vertical plate and the card plate, the vertical plate is fixed with two long screw rods, the two long screw rods are slidably connected to a movable plate, and the movable plate is pressed toward the vertical plate by nuts on the long screw rods, and the movable plate is provided with two pressure heads; when clamping the thrust rod seat, the pressure head and the guide rod respectively abut against two opposite sides of the thrust rod seat. The utility model adopts the elastically connected and replaceable card plate to position the thrust rod seat, can quickly clamp the thrust rod seat, improve production efficiency, can adapt to thrust rod seats of different specifications, and can achieve rapid installation without resetting the benchmark when installing the clamp.

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0015] like Figures 1-2 As shown, a thrust rod seat adapter clamp of the present embodiment includes a base plate 1, to which a vertical plate 2 and two support plates 3 perpendicular to the vertical plate 2 are fixed, the vertical plate 2 is slidably connected to a clamping plate 5 through two guide rods 4, the clamping plate 5 is in a "〔" shape, a screw rod 6 penetrating the clamping plate 5 and the vertical plate 2 is arranged between the clamping plate 5 and the vertical plate 2, the screw rod 6 is sleeved with a spring 7 whose two ends abut against the vertical plate 2 and the clamping plate 5, the vertical plate 2 is fixed with two long screw rods 8, the two long screw rods 8 are slidably connected to a movable plate 9, and the movable plate 9 is pressed toward the vertical plate 2 by the nuts on the long screw rods 8, and the movable plate 9 is provided with two pressing heads 10; when clamping the thrust rod seat, the pressing head 9 and the guide rod 4 respectively abut against two opposite sides of the thrust rod seat.

[0016] During operation, the thrust rod seat is placed on the support plate 3, and the front and rear surfaces of the thrust rod seat are engaged with the clamping plate 5, so that the thrust rod seat is automatically centered in the front and rear directions; then the movable plate 9 is slid to make the pressure head 10 contact the right side of the thrust rod seat, and the nut is locked so that the left and right sides of the thrust rod seat are respectively pressed by the front end of the guide rod 4 and the pressure head 10, thereby fixing the thrust rod seat. The fixture has a simple structure, is convenient for clamping the thrust rod seat, and the clamping plate 5 can be easily replaced, so that it can adapt to thrust rod seats of different specifications and sizes; in addition, the positioning and clamping of the thrust rod seat by the fixture is a centering positioning method, and the positioning references of thrust rod seats of different specifications are the same when positioning and clamping, so that when the fixture needs to process thrust rod seats of different specifications, there is no need to reset the positioning reference, which means that no matter what specifications of thrust rod seats are processed, when the fixture is replaced, there is no need to reset the installation reference on the machine tool.

[0017] A round steel pad 11 is provided between the bottom of the movable plate 9 and the side of the support plate 3. The diameter of the round steel pad 11 can be changed at any time, so that the movable plate 9 will not conflict with the support plate 3 when clamping for thrust rod seats of different widths.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, and for the convenience of describing the technical solution, the front, rear, left, right, top, middle, and bottom directions adopted are based on the settings in the accompanying drawings, rather than limiting the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
