Description

Technical Field

[0001] This application relates to the field of feeding equipment, and in particular to a feeding positioning table for cutting pump casing castings. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling, it is processed by subsequent means such as grinding to obtain an object with a certain shape, size and performance. During the casting production process, excess connecting parts need to be cut off.

[0003] Currently, when cutting excess parts of castings, a feeding positioning table is required. Some existing feeding positioning tables work by placing the casting on the positioning table, placing the two connecting rods on the casting in the grooves of the fixing block, and then using limiting plates to limit the casting and prevent it from moving. However, during use, the casting lacks fixation and is prone to shaking, which reduces stability. Utility Model Content

[0004] To address the aforementioned problems, this application provides a feeding and positioning platform for cutting pump casing castings.

[0005] The feeding and positioning platform for cutting pump casing castings provided in this application adopts the following technical solution:

[0006] A feeding positioning platform for cutting pump casing castings includes a positioning platform body and a casting body. The positioning platform body is provided with a pressing component to prevent the casting body from shaking. The pressing component includes multiple U-shaped fixing plates fixedly connected to the top of one side wall of the positioning platform body. The upper surface of the U-shaped fixing plates has placement grooves at both ends for placing the connecting rods of the casting body. Pressing plates are hinged to the upper surface of the U-shaped fixing plates on one side of the placement grooves. One end of the pressing plate is located above the placement groove. A receiving groove is formed on the upper surface of the U-shaped fixing plates below the pressing plates. A first connecting plate is hinged in the receiving groove. A second connecting plate is hinged to the lower surface of the pressing plate. The first connecting plate and the second connecting plate are hinged together. A spring is fixedly connected between the first connecting plate and the second connecting plate.

[0007] By adopting the above technical solution, during use, the pressure plate is pulled away from the placement groove, and then the casting body is placed into the U-shaped fixing plate, so that the connecting rods of the casting body are respectively located in the placement groove. Then, by releasing the pressure plate and pulling down the component, the pressure plate is brought closer to the placement groove and abuts against the connecting rods, fixing the casting body to the U-shaped fixing plate. This minimizes the problem of the casting lacking fixation during use, which can easily cause shaking and reduce stability.

[0008] Preferably, the pull-down assembly includes a plurality of receiving grooves formed on the upper surface of the U-shaped fixing plate and located below the pressure plate. A first connecting plate is hinged in the receiving groove. A second connecting plate is hinged to the end of the first connecting plate away from the receiving groove. The end of the second connecting plate away from the first connecting plate is hinged to the lower surface of the pressure plate. A spring is fixedly connected between the first connecting plate and the second connecting plate.

[0009] By adopting the above technical solution, when the pressure plate is pulled, the first connecting plate and the second connecting plate swing, which drives the spring to stretch. Then the pressure plate is released, and the spring rebounds, which can pull the pressure plate down and bring it close to the placement groove to abut against the connecting rod.

[0010] Preferably, the length of the pressure plate is greater than the length of the U-shaped fixing plate.

[0011] By adopting the above technical solution, when the pressure plate is attached to the U-shaped fixing plate, one end of the pressure plate can extend out to form the U-shaped fixing plate, preventing the pressure plate from being attached to the U-shaped fixing plate and making it difficult to pull the pressure plate.

[0012] Preferably, the upper surface of the positioning platform body has multiple mounting holes on all four sides, and the upper surface of the positioning platform body has multiple fixing bolts, the ends of the fixing bolts all passing through the mounting holes and forming a sliding arrangement.

[0013] By adopting the above technical solution, the positioning table body can be conveniently installed and fixed by passing the fixing bolt through the mounting hole and threading it to the external worktable.

[0014] Preferably, the upper surface of the positioning platform body has multiple receiving holes on all four sides for accommodating the nut ends of the fixing bolts.

[0015] By adopting the above technical solution, after the fixing bolt passes through the mounting hole, the nut end of the fixing bolt is located in the receiving hole, which can hide the fixing bolt and prevent the nut end of the fixing bolt from extending on the upper surface of the positioning table body and affecting its use.

[0016] Preferably, a rubber pad for increasing friction is fixedly connected to the lower surface of the pressure plate.

[0017] By adopting the above technical solution, when the pressure plate and the connecting rod abut against each other, the rubber pad abuts against the connecting rod, which can improve the stability of the pressure and prevent wear on the connecting rod.

[0018] Preferably, limiting plates are fixedly connected to the side walls of the U-shaped fixing plate, and the limiting plates are respectively located on one side of the placement groove.

[0019] By adopting the above technical solution, when the connecting rod is placed in the placement groove, one end of the connecting rod is made to fit with the limiting plate, which can prevent the connecting rod from sliding in the placement groove and improve the stability of the casting body installation.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application utilizes the cooperative arrangement of structures such as a U-shaped fixing plate, a placement groove, and a pressure plate. During use, by pulling the pressure plate away from the placement groove, the casting body is placed into the U-shaped fixing plate, so that the connecting rods of the casting body are respectively located in the placement groove. Then, by releasing the pressure plate and pulling down the assembly, the pressure plate is brought closer to the placement groove and abuts against the connecting rods, thus fixing the casting body onto the U-shaped fixing plate. This minimizes the problem of the casting lacking fixation during use, which can easily cause shaking and reduce stability.

[0022] 2. By passing the fixing bolt through the mounting hole and threading it to the external worktable, the positioning table body can be easily installed and fixed. After passing the fixing bolt through the mounting hole, the nut end of the fixing bolt is located in the receiving hole, which can hide the fixing bolt and prevent the nut end of the fixing bolt from extending on the upper surface of the positioning table body and affecting its use.

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0029] This application discloses a feeding and positioning platform for cutting pump casing castings.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A feeding positioning platform for cutting pump casing castings includes a positioning platform body 1 and a casting body 2. The positioning platform body 1 is provided with a pressing component to prevent the casting body 2 from shaking. The pressing component includes a U-shaped fixing plate 3, a placement groove 4 and a pressing plate 5.

[0031] Multiple U-shaped fixing plates 3 are provided, all of which are fixedly connected to the top of one side wall of the positioning platform body 1. Multiple placement slots 4 are provided, which are respectively opened at both ends of the upper surface of the U-shaped fixing plate 3 for placing the connecting rod of the casting body 2. Multiple pressure plates 5 are provided, which are respectively hinged to the upper surface of the U-shaped fixing plate 3 and located on one side of the placement slot 4. One end of the pressure plate 5 is located above the placement slot 4. The U-shaped fixing plate 3 is provided with a pull-down assembly for pulling the pressure plate 5.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The pull-down assembly includes multiple receiving slots 6 formed on the upper surface of the U-shaped fixed plate 3 and located below the pressure plate 5. A first connecting plate 7 is hinged in the receiving slot 6. A second connecting plate 8 is hinged to the end of the first connecting plate 7 away from the receiving slot 6. The end of the second connecting plate 8 away from the first connecting plate 7 is hinged to the lower surface of the pressure plate 5. A spring 9 is fixedly connected between the first connecting plate 7 and the second connecting plate 8. When the pressure plate 5 is pulled, the first connecting plate 7 and the second connecting plate 8 swing, causing the spring 9 to stretch. Then the pressure plate 5 is released, and the spring 9 rebounds, allowing the pressure plate 5 to be pulled down and brought close to the placement slot 4 to abut against the connecting rod.

[0033] Reference Figure 3 The length of the pressure plate 5 is greater than the length of the U-shaped fixing plate 3. When the pressure plate 5 is attached to the U-shaped fixing plate 3, one end of the pressure plate 5 can extend out of the U-shaped fixing plate 3 to prevent the pressure plate 5 from being attached to the U-shaped fixing plate 3 and making it difficult to pull the pressure plate 5.

[0034] Reference Figure 1 and Figure 4 The upper surface of the positioning platform body 1 has multiple mounting holes 10 on all four sides. The upper surface of the positioning platform body 1 has multiple fixing bolts 11. The screw ends of the fixing bolts 11 all pass through the mounting holes 10 and form a sliding setting. By passing the fixing bolts 11 through the mounting holes 10, they are threadedly connected to the external worktable, which facilitates the installation and fixing of the positioning platform body 1.

[0035] Reference Figure 1 and Figure 4The upper surface of the positioning platform body 1 has multiple receiving holes 12 on all four sides for accommodating the nut end of the fixing bolt 11. After the fixing bolt 11 is passed through the mounting hole 10, the nut end of the fixing bolt 11 is located in the receiving hole 12, which can hide the fixing bolt 11 and prevent the nut end of the fixing bolt 11 from extending on the upper surface of the positioning platform body 1 and affecting its use.

[0036] Reference Figure 3 A rubber pad 13 for increasing friction is fixedly connected to the lower surface of the pressure plate 5. When the pressure plate 5 abuts against the connecting rod, the rubber pad 13 abuts against the connecting rod, which can improve the stability of the pressure and prevent wear on the connecting rod.

[0037] Reference Figure 1 and Figure 2 Limiting plates 14 are fixedly connected to the two side walls of the U-shaped fixing plate 3. The limiting plates 14 are located on one side of the placement groove 4. When the connecting rod is placed in the placement groove 4, one end of the connecting rod is in contact with the limiting plate 14, which can prevent the connecting rod from sliding in the placement groove 4 and improve the stability of the casting body 2 installation.

[0038] The implementation principle of a feeding positioning platform for cutting pump casing castings according to an embodiment of this application is as follows: In use, by pulling the pressure plate 5 away from the placement groove 4, the casting body 2 is placed into the U-shaped fixing plate 3, so that the connecting rods of the casting body 2 are respectively located in the placement groove 4. When the pressure plate 5 is pulled, the first connecting plate 7 and the second connecting plate 8 swing, which drives the spring 9 to stretch. Then the pressure plate 5 is released, and the spring 9 rebounds, which can pull down the pressure plate 5, bringing the pressure plate 5 close to the placement groove 4 and abutting against the connecting rods, thus fixing the casting body 2 on the U-shaped fixing plate 3. This avoids the problem of the casting being unstable and prone to shaking during use due to lack of fixation.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
