Description

Technical Field

[0001] This invention relates to the field of spraying tooling technology, specifically to a tooling for improving the spraying efficiency of armature frames. Background Technology

[0002] Armature-type products are used in pressure reducing valves in the hydrogen supply systems of hydrogen fuel cell vehicles. Located in the engine compartment, these valves reduce the inlet pressure to a desired outlet pressure by adjusting the valve opening. They rely on the energy of the medium itself to automatically maintain a stable outlet pressure. Armature failure directly leads to pressure reducing valve failure, resulting in hydrogen leakage and fuel cell instability, affecting driving safety. Armature-type products have a very broad development prospect and huge future production capacity. However, in the process of applying adhesive to the frame, each frame needs to be precisely positioned for application, and current production efficiency is not high.

[0003] The existing spraying fixtures have the following shortcomings: 1. The spraying position needs to be accurately positioned before spraying each skeleton, resulting in low efficiency of applying adhesive to the skeleton; 2. The existing rubber fixtures are for single use, which increases the spraying cost.

[0004] To address the aforementioned shortcomings, a technical solution is provided. Summary of the Invention

[0005] The technical problem to be solved by this invention is as follows:

[0006] Existing spraying fixtures have problems such as requiring precise positioning of the spraying position before spraying each skeleton, resulting in low efficiency of applying adhesive to the skeleton; and existing rubber fixtures are disposable, which increases the spraying cost.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A tooling for improving the coating efficiency of armature frames includes an upper tooling plate and a lower tooling plate. The upper tooling plate is located above the lower tooling plate. A plurality of locking devices are provided between the upper and lower tooling plates, and the locking devices are arranged in a circular array on the sides of the upper and lower tooling plates. The upper and lower tooling plates are connected by the locking devices. A plurality of mold cores are provided at the bottom of the upper tooling plate, and the mold cores are arranged in a rectangular array at the bottom of the upper tooling plate. A receiving cavity is provided through the middle of each mold core, and a frame body is provided inside the receiving cavity. The size of the frame body is adapted to the inner diameter of the receiving cavity. A plurality of positioning components for positioning the frame body are provided at the top of the lower tooling plate, and the positioning components are adapted to the corresponding mold cores.

[0009] Furthermore, a number of support columns are fixedly installed on the top of the upper tooling plate, and the support columns are respectively fixedly installed at the four corners of the top of the upper tooling plate.

[0010] Furthermore, the bottom of the upper tooling plate is provided with several mounting grooves, the inner surface of the mounting grooves is provided with internal threads, the outer surface of the mold core is provided with external threads, and the mold core and the mounting grooves are connected by internal and external threads.

[0011] Furthermore, the top of the upper tooling plate is provided with a plurality of spray holes, and the plurality of spray holes correspond one-to-one with a plurality of mounting grooves, with one end of the spray hole extending into the corresponding mounting groove.

[0012] Furthermore, the locking device includes a locking shaft fixedly mounted on the top of the lower tooling plate, a locking handle sleeved on the outer side of the locking shaft, an external thread on the outer surface of the locking shaft, an internal thread on the inner surface of the locking handle, and the locking shaft and the locking handle are threadedly connected by the external thread and the internal thread.

[0013] Furthermore, the locking device also includes a locking hole through which the upper tooling plate is formed, the locking hole being adapted to a corresponding locking shaft.

[0014] Furthermore, the positioning component includes a positioning groove formed on the top of the lower tooling plate, a positioning seat slidably disposed in the positioning groove, a positioning plate fixedly disposed on the top of the positioning seat, and a positioning spring fixedly disposed between the positioning seat and the positioning groove.

[0015] Furthermore, the diameter of the positioning plate is smaller than the inner diameter of the mounting groove.

[0016] The beneficial effects of this invention are:

[0017] In this invention, the locking device and detachable mold core enable precise positioning of the frame body in both the horizontal and vertical directions. Each mold core is independently fixed on the upper tooling plate, ensuring that the positioning of each frame body does not affect each other and there is no cumulative error. This allows for the large-scale and efficient spraying of armature frames that require precise positioning of the spraying surface.

[0018] By setting up mounting slots, the mold core can be quickly assembled and disassembled on the upper tooling plate, making it easy to replace mold cores with different cavity diameters, thereby meeting the synchronous spraying requirements of different specifications of skeleton bodies.

[0019] By setting up a locking device and positioning components, several locking shafts pass through corresponding locking holes. By rotating the locking handle, the shafts move until they abut against the top of the upper tooling plate, ensuring a tight connection between the upper and lower tooling plates and guaranteeing the stability of the connection. The positioning spring compresses the positioning seat, causing it to slide within the positioning groove. This, in turn, pushes the positioning plate against the bottom of the skeleton body, ensuring that the skeleton body is properly installed within the mold core. The lower tooling plate and positioning components facilitate vertical positioning of the skeleton body, improving stability and accuracy during the painting process. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 The present invention provides a technical solution:

[0032] A tooling for improving the efficiency of armature frame spraying includes an upper tooling plate 1 and a lower tooling plate 2. The upper tooling plate 1 is located above the lower tooling plate 2. A plurality of locking devices 3 are provided between the upper tooling plate 1 and the lower tooling plate 2. The plurality of locking devices 3 are arranged in a circular array on the sides of the upper tooling plate 1 and the lower tooling plate 2. The upper tooling plate 1 and the lower tooling plate 2 are connected by the locking devices 3. A plurality of mold cores 4 are provided at the bottom of the upper tooling plate 1. The plurality of mold cores 4 are arranged in a rectangular array at the bottom of the upper tooling plate 1. A receiving cavity is provided through the middle of the mold core 4. A frame body 5 is provided inside the receiving cavity. The size of the frame body 5 is adapted to the inner diameter of the receiving cavity, so that the frame body 5 is precisely locked in the corresponding receiving cavity, completing the horizontal positioning of the frame body 5. A plurality of positioning components 6 are provided at the top of the lower tooling plate 2 for positioning the frame body 5. The plurality of positioning components 6 are adapted to the corresponding mold cores 4.

[0033] A number of support columns 101 are fixedly installed on the top of the upper tooling plate 1. The support columns 101 are respectively fixedly installed at the four corners of the top of the upper tooling plate 1 to facilitate the support of the tooling as a whole.

[0034] The bottom of the upper tooling plate 1 is provided with a plurality of mounting grooves 401. The inner surface of the mounting grooves 401 is provided with internal threads, and the outer surface of the mold core 4 is provided with external threads. The mold core 4 and the mounting grooves 401 are connected by internal and external threads.

[0035] The cavity of the mold core 4 can have different diameters to meet the positioning requirements of different specifications of the skeleton body 5. By setting the mounting groove 401, the mold core 4 can be quickly disassembled and assembled on the upper tooling plate 1, which facilitates the replacement of mold cores 4 with different cavity diameters, thereby meeting the synchronous spraying requirements of different specifications of the skeleton body 5.

[0036] The top of the upper tooling plate 1 is provided with a plurality of spray holes 102, and the plurality of spray holes 102 correspond one-to-one with a plurality of mounting grooves 401, with one end of the spray hole 102 extending into the interior of the corresponding mounting groove 401.

[0037] The locking device 3 includes a locking shaft 301 fixedly mounted on the top of the lower tooling plate 2. A locking handle 302 is sleeved on the outer side of the locking shaft 301. The outer surface of the locking shaft 301 is provided with an external thread, and the inner surface of the locking handle 302 is provided with an internal thread. The locking shaft 301 and the locking handle 302 are threadedly connected by the external thread and the internal thread.

[0038] The locking device 3 also includes a locking hole 303 that passes through the upper tooling plate 1, and the locking hole 303 is adapted to the corresponding locking shaft 301. By setting the locking device 3, several locking shafts 301 pass through the corresponding locking holes 303, and by rotating the locking handle 302, they move on the locking shafts 301 until they abut against the top of the upper tooling plate 1, thus ensuring a tight connection between the upper tooling plate 1 and the lower tooling plate 2 and guaranteeing the stability of the connection.

[0039] The positioning component 6 includes a positioning groove 601 formed on the top of the lower tooling plate 2, a positioning seat 602 slidably disposed in the positioning groove 601, a positioning plate 603 fixedly disposed on the top of the positioning seat 602, and a positioning spring 604 fixedly disposed between the positioning seat 602 and the positioning groove 601.

[0040] The diameter of the positioning plate 603 is smaller than the inner diameter of the mounting groove 401, allowing the positioning plate 603 to extend into the mounting groove 401 and thus position the skeleton body 5. The positioning component 6 causes the positioning spring 604 to press against the positioning seat 602, causing the positioning seat 602 to slide within the positioning groove 601. This, in turn, pushes the bottom of the skeleton body 5 with the positioning plate 603, ensuring the skeleton body 5 is properly installed within the mold core 4. The lower tooling plate 2 and the positioning component 6 facilitate vertical positioning of the skeleton body 5, improving stability and accuracy during the painting process.

[0041] Working principle:

[0042] In use, according to the specifications of the skeleton body 5, different mold cores 4 are replaced in the mounting groove 401, and the skeleton body 5 is placed in the placement cavity of the corresponding mold core 4. Several locking shafts 301 are passed through the corresponding locking holes 303, and the locking handle 302 is rotated to move it on the locking shaft 301 until it abuts against the top of the upper tooling plate 1, so that the upper tooling plate 1 and the lower tooling plate 2 are tightly connected. The positioning spring 604 squeezes the positioning seat 602, causing the positioning seat 602 to slide in the positioning groove 601, and causing the positioning plate 603 to push the bottom of the skeleton body 5, thereby ensuring that the skeleton body 5 is installed in the mold core 4. Then, the adhesive is sprayed on the skeleton body 5 through the spraying hole 102.

[0043] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
