Description

Technical Field

[0001] This utility model belongs to the field of spraying technology, and in particular relates to a spraying displacement device for high-pressure pump housing. Background Technology

[0002] As the core pressure-bearing component of the hydraulic system, the high-pressure pump housing is usually made of high-strength ductile iron or precipitation-hardening stainless steel through precision casting and five-axis machining. Its interior needs to be constructed with a sealed chamber that can withstand extreme pressure. The dynamic sealing of the piston assembly is ensured through high-precision mating surfaces, and the geometric stability is maintained under continuous pulsating impact, media corrosion and thermal load (ΔT>150℃) environment, thereby ensuring a maintenance-free operating life of more than ten years for the hydraulic system.

[0003] Currently, high-pressure pump housing spraying production lines generally adopt a fixed single-station design, meaning that each spraying system can only perform the entire process of sandblasting pretreatment → preheating → functional layer spraying (such as HVOF deposition of WC-10Co-4Cr) → cooling → inspection on a single housing in sequence. Although this mode can cover complex surfaces through multi-axis linkage of robotic arms, the repeated clamping of the housing at a single station in related technologies has resulted in a long-term low overall utilization rate of the equipment and the inability to achieve continuous production. Utility Model Content

[0004] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A spraying displacement device for a high-pressure pump housing includes an operating table, two mounting plates, two transfer mechanisms, two housing clamping mechanisms, two support plates, two drive mechanisms, and two staggered telescopic mechanisms.

[0007] The two transfer mechanisms are symmetrically arranged on the operating table;

[0008] The moving end of each transfer mechanism is slidably connected to the corresponding support plate, and a housing clamping mechanism is fixedly provided on the upper end surface of the support plate.

[0009] The outer end of each support plate is slidably connected to the operating table surface through an interlaced telescopic mechanism;

[0010] The two drive mechanisms are symmetrically arranged on the lower end surface of the operating table, and the output end of each drive mechanism is connected to the corresponding transfer mechanism.

[0011] The two mounting plates are symmetrically fixed at the left and right ends of the operating table.

[0012] Furthermore, the transfer mechanism includes a linear slide rail, a transfer support structure, and a horizontal plate. The operating table is provided with a sliding groove, and the transfer support structure is slidably disposed in the sliding groove. The transfer support structure is slidably engaged with the upper end surface of the operating table via the linear slide rail. The horizontal plate is disposed on the top of the transfer support structure, and the upper end surface of the horizontal plate is slidably engaged with the lower end surface of the support plate via a guide structure.

[0013] Furthermore, the transfer support structure includes a sliding base, a support rod, and a drive plate. The horizontal plate is provided on the top of the sliding base, the bottom of the sliding base is slidably engaged with the linear slide rail, the side of the sliding base is fixedly connected to the top of the support rod, the drive plate is provided at the bottom of the support rod, and the drive plate is connected to the output end of the drive mechanism.

[0014] Furthermore, the guide structure includes two parallel guide rails, both of which are disposed on the upper surface of the horizontal plate, and the support plate slides in cooperation with the two guide rails.

[0015] Furthermore, the housing clamping mechanism includes a fixed plate, two fixed bases, a fastening rod, two guide slide rods and fastening rods, two guide slide rods and two clamping bases;

[0016] The fixing plate is fixedly mounted on the upper end face of the support plate;

[0017] Two fixed bases are symmetrically fixed on the upper surface of the fixed plate;

[0018] Two guide slides are arranged side by side between two fixed bases, and the two ends of each guide slide are fixedly connected to the corresponding fixed base;

[0019] The fastening rod is rotatably connected to two fixed bases;

[0020] Two clamping bases are symmetrically arranged on the fastening rod, and the fastening rod drives the two clamping bases to move towards each other and away from each other along the guide slide rod through opposite threaded structures;

[0021] Each clamping base is slidably engaged with two guide rods.

[0022] Furthermore, the staggered telescopic mechanism includes a positioning rod and a stroke hole;

[0023] The top of the positioning rod is fixedly connected to the support plate;

[0024] The bottom of the positioning rod is slidably connected to the stroke hole;

[0025] The travel hole consists of two straight hole segments and an arched hole segment connecting the two straight hole segments;

[0026] When the middle arched section of the travel hole engages with the positioning rod, it causes the positioning rod to shift radially, thus moving the support plate outward.

[0027] Furthermore, the drive mechanism includes a threaded rod, a servo motor, and two fixed support plates;

[0028] Two fixed support plates are symmetrically arranged on the lower end face of the operating table;

[0029] The threaded rod is rotatably mounted on two fixed support plates;

[0030] The output shaft of the servo motor is fixedly connected to the threaded rod coaxially.

[0031] The threaded rod is threadedly connected to the drive plate of the transplanting mechanism.

[0032] Compared with the prior art, the spray positioning device for high-pressure pump housing described in this utility model has the following advantages:

[0033] 1. Through the symmetrical layout of the dual-station collaborative mechanism, the spraying process and the workpiece loading and unloading process can be carried out in parallel, eliminating the waiting time of the robotic arm in the single-station mode, thereby improving the effective operating rate of the high-pressure pump housing spraying line. It is especially suitable for multi-process long-cycle production scenarios of sandblasting pretreatment → functional layer deposition → inspection.

[0034] 2. Based on the forced displacement design of the arched section of the stroke hole, the radial offset motion of the support plate is superimposed during the linear retraction of the transfer mechanism, so that the workpiece completes the workstation exchange during the reset stage. This avoids the need for additional transfer tables or robotic arm gripping actions in traditional production lines, and enables the high-pressure pump housing to be transferred without interruption in the continuous production flow, shortening the single-piece production cycle of the original mode.

[0047] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] A spraying positioning device for high-pressure pump housings addresses the technical shortcomings of current fixed single-station spraying lines, namely low equipment utilization and inability to achieve continuous production, by constructing a dual-station collaborative positioning system. Its core structure includes a horizontally positioned operating table 100, with symmetrically fixed mounting plates 110 at the left and right ends of the operating table 100 for integration into the production line.

[0049] Two transplanting mechanisms are mirror-distributed on the upper surface of the operating table 100. Each transplanting mechanism consists of a linear slide rail 310, a sliding base, a vertical support rod, and a top horizontal plate 200. The sliding base is nested in the sliding slot of the operating table 100 and moves back and forth along the linear slide rail 310. The bottom of the support rod extends to the bottom of the operating table 100 and is fixed to the drive plate. Two parallel guide slide rails 210 are provided on the upper surface of the top horizontal plate 200.

[0050] Two support plates 400 are slidably connected to the corresponding transplanting mechanism via guide slide rails 210. The upper end face of the support plate 400 is fixed to the housing clamping mechanism 500. The clamping mechanism includes a fixed plate 510, two fixed bases 520 symmetrically fixed to the fixed plate 510, two guide slide rods connecting the two bases, a rotatable fastening rod 530 penetrating the base, and two clamping bases 540 symmetrically sleeved on the fastening rod 530. The fastening rod 530 is designed with a reverse thread structure to drive the clamping bases 540 to move synchronously towards or away from each other along the guide slide rods.

[0051] The outer end of each support plate 400 is linked to the operating table 100 through an interleaved telescopic mechanism 600. The interleaved telescopic mechanism 600 consists of a positioning rod 610 fixed to the support plate 400 and a stroke hole 620 opened in the operating table 100. The stroke hole 620 is composed of two straight hole sections and a central arched hole section connected together. The bottom end of the positioning rod 610 is slidably engaged with the stroke hole 620. Two sets of drive mechanisms are symmetrically arranged on the lower end face of the operating table 100. Each set of drive mechanisms includes a servo motor and a threaded rod rotatably supported by two fixed support plates. The output shaft of the servo motor is coaxially fixed to the threaded rod, and the threaded rod and the drive plate of the transplanting mechanism form a threaded transmission pair.

[0052] How this example works

[0053] Step 1: Alternating spraying and loading / unloading at dual workstations: When the left housing clamping mechanism 500 clamps the workpiece to perform the spraying process, the right drive mechanism pushes the corresponding transfer mechanism forward through the threaded rod, so that the right housing clamping mechanism 500 enters the loading / unloading station;

[0054] Step 2, displacement superposition during workstation switching: After the left side is sprayed, the drive mechanism on this side rotates the threaded rod in the opposite direction to retract the transfer mechanism, and the positioning rod 610 moves along the straight section of the stroke hole 620; when the positioning rod 610 enters the arched hole section, it generates radial offset, forcing the support plate 400 to slide outward, so that the workpiece on the left side is moved out of the spraying area.

[0055] Step 3, Continuous Production Connection: The right-side transfer mechanism moves forward synchronously, and its positioning rod 610 slides along the arched hole section to push the support plate 400 back to the spraying center, realizing the exchange of spatial positions of the workpieces in the two stations, and at the same time, the new workpiece enters the spraying process.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
