DETAILED DESCRIPTION

[0020] In order to more clearly understand the technical means of the utility model, and can be implemented according to the content of the specification, the specific embodiments of the utility model are further described in detail below, the following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0021] Referring to the accompanying drawings Figures 1-4As shown, the machining jig of the vehicle heating converter pump body of the first embodiment comprises a base 1; a fixing mechanism arranged on the base 1 and capable of fixing the pump body; a pressing mechanism for multi-directional auxiliary fixing of the pump body; and an inner support mechanism arranged on the base 1 and used for supporting the interior of the pump body.

[0022] After the pump body is placed on the base 1, the pump body can be fixed by the fixing mechanism and then pressed by the pressing mechanism at multiple points, thereby improving the firmness of the pump body after being fixed and preventing the pump body from being deviated during subsequent work. The inner support mechanism can support the interior of the pump body, and the pump body is more stable when being pressed in cooperation with the pressing mechanism and the fixing mechanism.

[0023] The inner support mechanism comprises a vertical column 4 arranged vertically on the base 1, an inner support 41 arranged on the vertical column 4 and capable of adjusting the height, and a contact block 42 arranged at the top of the inner support 41 and used for contacting the interior shell of the pump body.

[0024] The vertical column 4 can adjust the height of the contact block 42, so that the contact block 42 can contact the top end of the interior of the pump body and support it. Since the height of the inner support 41 is adjustable, the height of the contact block 42 can be adjusted to adapt to pump bodies with different internal heights, thereby improving the practicability. Since the contact block 42 is detachably arranged, it can be maintained and replaced when its service life is over. The material of the contact block 42 is preferably rubber, which can increase the friction and can also be used for buffering.

[0025] Further, an inner thread 43 is vertically arranged in the interior of the vertical column 4, and an outer thread 44 is arranged on the outer wall of the inner support 41 and is adapted to the inner thread 43.

[0026] When the inner support 41 is rotated, the outer thread 44 can be threadedly connected with the inner thread 43, thereby installing the inner support 41 and adjusting the height position by the thread.

[0027] Further, a clamping sleeve 45 for installing the contact block 42 is arranged in the interior of the inner support 41, a connecting sleeve 46 is embedded in the bottom of the inner support 41, and a screw rod 47 is arranged in the interior of the inner support 41 and penetrates the clamping sleeve 45 and the connecting sleeve 46, and the screw rod 47 is threadedly connected with the connecting sleeve 46 and the clamping sleeve 45, respectively.

[0028] When it is necessary to replace the clamping sleeve 45 and install a larger contact block 42 or a smaller contact block 42, the screw rod 47 is rotated by a screwdriver to be separated from the thread connection with the connecting sleeve 46, so that the clamping sleeve 45 can be removed, and vice versa.

[0029] Further, the vertical column 4 is fixed to the base 1 by a long tube screw.

[0030] Further, the fixing mechanism comprises a fixing block 2, an electric telescopic rod 21 fixed on the fixing block 2, and a pressing piece 22 arranged at an output end of the electric telescopic rod 21.

[0031] The electric telescopic rod 21 can drive the pressing piece 22 to descend in operation, so that the shell can be fixed by the pressing pressing piece 22.

[0032] Further, one end of the pressing piece 22 is threadedly connected with a bolt 23, and the bolt 23 is threadedly connected with a nut 24.

[0033] Since one end of the pressing piece 22 is threadedly connected with the bolt 23, the bolt 23 can adjust the pressing height in a threaded manner, improve the applicability, and the nut 24 can increase the pressing area, increase the stability, and facilitate the fixation of the bolt 23.

[0034] Further, the pressing mechanism comprises a cylinder 3 mounted on the base 1, a connecting seat 31 arranged on the cylinder 3, and an extruding piece 32 rotatably arranged on an output shaft of the cylinder 3, and the extruding piece 32 is rotatably connected with the connecting seat 31.

[0035] The cylinder 3 can drive the extruding piece 32 to descend in operation, since the extruding piece 32 is rotatably connected with the connecting seat 31 and the extruding piece 32 is rotatably connected with the cylinder 3, the cylinder 3 can drive the other end of the extruding piece 32 to descend while the output end of the cylinder 3 rises in operation, so that the extruding piece 32 is extruded and fixed.

[0036] Further, the base 1 is provided with a positioning rod 11 for positioning the pump body, and the base 1 is further provided with a bottom pad 12 for supporting the pump body.

[0037] The positioning rod 11 facilitates the guiding and positioning of the preliminary placement of the pump body, and the bottom pad 12 can avoid the direct contact of the pump body with the base 1, and when the bottom pad 12 is soft, the pump body can be effectively protected.

[0038] The above only describes preferred embodiments of the present application, and is not used to limit the present application, and it should be pointed out that, for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection scope of the present application.
