Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular, to a lathe and a special clamping fixture for the main housing of a metering pump. Background Technology

[0002] like Figure 1 and Figure 2 The diagram shows the structure of the metering pump main housing 1. Currently, the connecting surface 10 of the main housing 1 needs to be machined. A lathe 2 is used to machine the main housing 1. However, because the main housing 1 has an irregular shape, the three-jaw chuck cannot stably clamp it. Therefore, how to stably fix the main housing 1 on the lathe 2 is a problem that urgently needs to be solved. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a special clamping fixture for a lathe and its metering pump main housing, so as to facilitate the clamping of the metering pump main housing.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a special clamping fixture for the main body of a metering pump, including a support plate connected to a transition plate of a lathe, a raised block connected to the support plate for abutting against the end face of the main body, a positioning plate fixedly connected to the raised block, the positioning plate for embedding into the end hole of the main body, a positioning post connected to the support plate, a pressure plate provided on the positioning post, a locking sleeve threadedly connected to the positioning post for abutting against the side of the pressure plate opposite to the main body, the pressure plate abutting against the side of the main body opposite to the raised block, an extension tube connected to the positioning plate, the end of the extension tube having a slot, the slot for cooperating with the reinforcing rib of the main body to restrict the rotation of the main body.

[0005] To achieve the above technical solution, the support plate is fixed on the lathe, and the end face of the metering pump main housing faces the shim block, so that the end face abuts against the shim block, making the support of the main housing suspended. The positioning plate is embedded in the end hole to restrict the movement of the main housing. At the same time, the slot on the extension tube is fitted onto the outer wall of the reinforcing rib, thereby restricting the rotation of the main housing. At this time, the connecting surface of the main housing remains positioned. Then, the pressure plate is slidably connected to the positioning post, so that the pressure plate abuts against the main housing. Finally, the locking sleeve is threadedly connected to the positioning post, so that the locking sleeve abuts against the pressure plate. The pressure plate applies pressure to the main housing, so that the main housing cannot be separated from the shim block, thereby achieving clamping and fixing of the main housing, which is convenient for installation. When the support plate rotates, the lathe tool can machine the connecting surface.

[0006] As a preferred embodiment of this utility model, the support plate includes a fixed plate, a horizontal plate, and a counterweight. The fixed plate is fixed to the transition plate of the lathe, the horizontal plate is vertically fixed to the fixed plate and is used to support the main housing, the counterweight is connected to the fixed plate, and the counterweight and the horizontal plate are located on both sides of the main housing.

[0007] To achieve the above technical solution, the fixing plate is fixed on the transition plate of the lathe. Since the shim supports the main housing, the axis of the connecting surface can be parallel to the axis of the transition plate. When the transition plate rotates, the main housing is more stable on the horizontal plate. In addition, the counterweight rotates synchronously with the fixing plate to make the dynamic balance of the fixing plate more stable, so that the main housing is more stable when it rotates with the transition plate.

[0008] As a preferred embodiment of this utility model, the pressure plate has a placement groove on the side facing the main body, and a protective pad for abutting against the outer wall of the main body is connected in the placement groove.

[0009] By implementing the above technical solution, the protective pad can enhance the protection of the outer wall of the main enclosure and reduce the occurrence of scratches on the outer wall of the main enclosure.

[0010] As a preferred embodiment of this utility model, the end of the extension tube is provided with a guide slope, and the guide slope is connected to the slot.

[0011] To achieve the above technical solution, the extension tube extends into the main housing, and the guiding effect of the guide slope facilitates the placement of the reinforcing rib in the slot, thereby improving the connection efficiency between the extension tube and the reinforcing rib.

[0012] As a preferred embodiment of this utility model, a placement recess is provided on the side wall of the positioning plate, an anti-detachment plate is slidably connected in the placement recess, a connecting inclined surface is provided on the anti-detachment plate, an elastic element is connected between the inner wall of the placement recess and the anti-detachment plate, and the side of the anti-detachment plate away from the placement recess is used to abut against the inner wall of the end hole of the main body.

[0013] To achieve the above technical solution, the positioning plate is aligned with the end hole, the inner wall of the end hole moves along the side wall of the positioning plate, and the connecting inclined surface abuts against the opening of the end hole. Through the guiding action of the connecting inclined surface, the anti-detachment plate is completely pressed into the placement recess. When the positioning plate is placed in the end hole, the elastic force of the elastic element makes the anti-detachment plate abut against the inner wall of the end hole, and the resulting friction makes the main body more stable on the support plate.

[0014] As a preferred embodiment of this utility model, an anti-slip pad is fixedly connected to the side of the anti-detachment plate away from the placement recess.

[0015] The above technical solution enables the anti-slip pad to contact the inner wall of the end hole, increasing friction and making the main body more stable on the support plate.

[0016] In a preferred embodiment of this utility model, the locking sleeve is integrally connected to a contact ring on the side facing the pressure plate. The cross-sectional area of ​​the contact ring is larger than that of the locking sleeve, and the contact ring abuts against the pressure plate.

[0017] To achieve the above technical solution, the contact ring increases the contact area between the locking sleeve and the pressure plate to increase friction, thereby making the connection between the pressure plate and the main housing more stable.

[0018] This utility model also discloses a lathe, including a special clamping fixture for the main body of a metering pump and a transition plate, wherein the support plate is fixed on the transition plate.

[0019] To achieve the above technical solution, the three-jaw chuck is removed from the transition plate, and then the support plate is fixed on the transition plate. The main housing is raised by shims so that the axis of the end hole of the main housing is parallel to the axis of the transition plate. Attached Figure Description

Detailed Implementation

[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0029] Example 1: A special clamping fixture for the main body of a metering pump includes a support plate 3. The three-jaw chuck on the lathe 2 is removed from the transition plate 21 of the lathe 2, and the support plate 3 is connected to the transition plate 21.

[0030] The support plate 3 includes a fixed plate 31, a horizontal plate 32, and a counterweight 33. The fixed plate 31 is disc-shaped and fixed to the transition plate 21 of the lathe 2, with the fixed plate 31 and the transition plate 21 coaxially arranged. The horizontal plate 32 is vertically fixed to the fixed plate 31 and supports the main housing 1, with the horizontal plate 32 located near the edge of the fixed plate 31. The counterweight 33 is connected to the fixed plate 31, and the counterweight 33 and the horizontal plate 32 are located on opposite sides of the main housing 1 to balance its weight.

[0031] A shim 4 is connected to the horizontal plate 32 to abut against the end face 12 of the main housing 1. The shim 4 provides support, allowing the extended axis of the fixing plate 31 to pass through the axis of the connecting surface 10 on the main housing 1, while simultaneously suspending the support 11 of the main housing 1. A disc-shaped positioning plate 41 is fixedly connected to the shim 4, and the positioning plate 41 is used to embed into the end hole 13 of the main housing 1. At this time, the main housing 1 can rotate along the axis of the end hole 13.

[0032] To ensure a more stable connection between the positioning plate 41 and the end hole 13, a square-section recess 42 is provided on the side wall of the positioning plate 41. An anti-detachment plate 43 is slidably connected within the recess 42, and a connecting inclined surface 44 is provided on the anti-detachment plate 43. An elastic element 45 connects the inner wall of the recess 42 and the anti-detachment plate 43. The side of the anti-detachment plate 43 away from the recess 42 is used to abut against the inner wall of the end hole 13 of the main housing 1. This prevents the main housing 1 from rotating along the axis of the end hole 13. The elastic element 45 is a spring.

[0033] Place the horizontal plate 32 horizontally, and move the main box 1 from top to bottom towards the support block 4. Align the positioning plate 41 with the end hole 13. The inner wall of the end hole 13 moves along the side wall of the positioning plate 41. The connecting inclined surface 44 abuts against the opening of the end hole 13. Through the guiding action of the connecting inclined surface 44, the anti-detachment plate 43 is completely pressed into the placement recess 42. When the positioning plate 41 is placed in the end hole 13, the elastic force of the elastic element 45 makes the anti-detachment plate 43 abut against the inner wall of the end hole 13. The resulting friction makes the main box 1 more stable on the support plate 3. Then, continue to move the main box 1 down so that the end face 12 abuts against the upper surface of the support block 4.

[0034] An anti-slip pad 46 is fixedly connected to the side of the anti-slip plate 43 away from the placement recess 42. The anti-slip pad 46 is made of rubber.

[0035] An extension tube 5 is connected to the positioning plate 41. The end of the extension tube 5 is provided with a slot 51. The slot 51 is used to cooperate with the reinforcing rib 14 of the main box 1 to restrict the rotation of the main box 1.

[0036] A guide slope 52 is provided at the end of the extension tube 5, and the guide slope 52 is connected to the slot 51.

[0037] After the anti-detachment plate 43 aligns with the inner wall of the end hole 13, the main box 1 is moved further down so that the end face 12 abuts against the upper surface of the shim block 4, and the reinforcing rib 14 is placed in the slot 51 to restrict the main box 1 from rotating along the axis of the end hole 13 on the support plate 3.

[0038] Positioning posts 6 are vertically fixed to the support plate 3. There are two positioning posts 6, located on both sides of the main housing 1. A pressure plate 7 is provided on the positioning post 6. The pressure plate 7 has round holes at both ends. The positioning posts 6 pass through the round holes. Under the action of gravity, the pressure plate 7 presses against the upper surface of the main housing 1. A locking sleeve 8 is threadedly connected to the positioning post 6 to abut against the side of the pressure plate 7 opposite to the main housing 1. The pressure plate 7 abuts against the main housing 1. By tightening the locking sleeve 8, the pressure plate 7 applies a clamping force to the main housing 1, thereby completely fixing the main housing 1.

[0039] A contact ring 81 is integrally connected to the side of the locking sleeve 8 facing the pressure plate 7. The cross-sectional area of ​​the contact ring 81 is larger than that of the locking sleeve 8, and the contact ring 81 abuts against the pressure plate 7.

[0040] A placement groove 9 is provided on the side of the pressure plate 7 facing the main housing 1, and a protective pad 91 for abutting against the outer wall of the main housing 1 is fixedly connected in the placement groove 9. The protective pad 91 is made of rubber.

[0041] Example 2: A lathe, including a metering pump main housing special clamping fixture and a transition plate 21 as described in Example 1, wherein a fixing plate 31 is fixed to the transition plate 21 by bolts, and the fixing plate 31 and the transition plate 21 are coaxially arranged.

[0042] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
