Problems solved by technology

[0003] The invention provides an auxiliary device for hole processing of a pump head. By pre-setting an auxiliary processing hole with high dimensional accuracy on the auxiliary device, and then positioning the workpiece on the auxiliary device, it is possible to avoid looking for a reference, Steps such as scribing can directly identify the auxiliary machining hole and process the precise hole on one side of the pump head, which not only saves time but also improves the dimensional accuracy, and solves the problem of complex and low precision in the previous pump head hole processing process

Embodiment 1

[0019] Such as figure 1 , figure 2 The hole processing auxiliary device for the pump head shown includes an upper fixture 2 and a lower fixture 4, the upper fixture 2 and the lower fixture 4 are connected by a connecting rod 5, and a pump head installation cavity is left between the upper fixture 2 and the lower fixture 4 3. The upper end surface of the upper fixture 2 is provided with a plurality of vertical auxiliary holes 1 passing through the upper fixture 2 .

[0020] In the application of this embodiment, the pump head is directly placed in the pump head installation cavity 3, the upper fixture 2 and the lower fixture 4 are connected through the connecting rod 5, and the distance between the upper fixture 2 and the lower fixture 4 is adjusted to place the pump head Clamp and position, and then fix the upper fixture 2 and the lower fixture 4 through the external fixing device to drill the hole. When drilling, the drill bit passes through the vertical auxiliary hole 1 so...

Embodiment 2

[0022] This embodiment optimizes the upper fixture on the basis of Example 1, specifically: the upper fixture 2 includes an upper fixture square plate 9, and the left side of the upper fixture square plate 9 is located at two corners. The fixture positioning part 8, the upper fixture positioning part 8 is provided with a vertical through hole 7, and the lower end surface of the upper fixture square plate 9 is provided with a concave positioning groove.

[0023] In this embodiment, the vertical through hole 7 of the upper fixture 2 cooperates with the connecting rod 5 to realize the connection between the upper fixture (2) and the lower fixture (4) and clamp the pump head. The upper end surface of the pump head can be clamped on the square of the upper fixture In the positioning groove of the lower end face of the plate 9, the positioning is strengthened.

Embodiment 3

[0025] This embodiment adds the following structure on the basis of embodiment 2: the front and rear sides of the upper end surface of the square plate 9 of the upper fixture are provided with locking grooves 10 .

[0026] The clamping groove 10 of this embodiment can be used for an external fixture to compress the square plate 9 of the upper fixture, so as to avoid accidents such as drilling errors and drill stuck due to displacement of the square plate 9 of the upper fixture during drilling, and improve safety.

Abstract

The invention discloses a hole machining auxiliary device for a pump head. The hole machining auxiliary device comprises an upper fixture (2) and a lower fixture (4) which are connected through a connecting rod (5), a pump head mounting cavity (3) is reserved between the upper fixture (2) and the lower fixture (4), and a plurality of vertical auxiliary holes (1) penetrating the upper fixture (2) are formed in the upper end face of the upper fixture (2). The hole machining auxiliary device for the high-pressure pump head can be used for rapidly machining through holes in a single face of the pump head in batch, and is simple and convenient to operate and high in machining efficiency and hole machining dimensional precision.

Description

technical field [0001] The invention relates to a hole processing auxiliary device, more specifically relates to a hole processing auxiliary device of a pump head. Background technique [0002] There are multiple through-holes for gas or liquid circulation on the high-pressure pump head, such as through-holes such as discharge holes, shunt holes, and pressure-reducing holes. In order to meet the needs of assembly and use, these through-holes need to meet the mutual The size requirements include the hole diameter, the distance between the hole and the edge, and the distance between the hole and the hole. The center of each hole is marked out with multiple reference lines, and then the center of the marked hole is used to process the hole. The process is not only complicated, but also when there is a small deviation in the marking line, there will be a large error in the processing size, so that the size The workpiece with large error is scrapped, and the machining accuracy i...
