Description

Technical Field

[0001] The utility model relates to the technical field of cylinder skirt frame installation, in particular to a group frame pressing pipe fixture. Background Art

[0002] The cylinder block skirt is a component used in internal combustion engines. Its primary function is to be fixed to the lower surface of the cylinder block. It connects to the cylinder block bottom surface through a sealing structure, and is connected to the oil collector and oil pan below. It also connects to the oil pump and rear oil seal cover assembly to form an integral whole. This design is intended to improve the efficiency and performance of the internal combustion engine.

[0003] During installation, a hydraulic structure is generally used to connect and install the cylinder skirt with the cylinder shell, and multiple structures can be installed simultaneously. However, when the hydraulic structure is conventionally used to operate it, manual auxiliary operation is generally used to connect the structures, and the hydraulic device is manually used to connect and install it, which can easily cause improper installation or pressure leakage.

[0004] Therefore, in view of this, the existing structure and defects were studied and improved, and a group frame pipe pressing fixture was proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a group frame pipe pressing fixture to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a group-frame pipe pressing jig, comprising a jig assembly and a jig frame assembly, a first hydraulic cylinder being symmetrically installed at the bottom of the jig assembly, a pipe pressing assembly being installed directly above the first hydraulic cylinder, and a second hydraulic cylinder being vertically installed in the middle of the top of the pipe pressing assembly, the jig frame assembly being connected to the end of the second hydraulic cylinder away from the pipe pressing assembly, the jig frame assembly comprising a main frame body, guide rails, a servo motor, a bidirectional screw rod and a guide pile, a guide rail being symmetrically installed at one side of the main frame body close to the jig assembly, a servo motor being installed at the upper ends of the left and right sides of the main frame body, and a bidirectional screw rod being vertically installed at the bottom power output end of the servo motor through a coupling, and guide piles being installed at both upper and lower ends of the bidirectional screw rod.

[0007] Furthermore, the jig assembly includes a jig table, a first limit block, a second limit block and a third limit block. The first limit block is installed on the front edge of the top surface of the jig table, and the second limit block is installed on the rear edge of the top surface of the jig table, and the third limit block is installed on one side edge of the top surface of the jig table.

[0008] Furthermore, the fixture assembly includes a support frame, a movable frame and a first slider. The support frame is symmetrically installed on the bottom of the fixture table, and the movable frame is installed on the bottom of the support frame, and the first slider is installed on one end of the movable frame.

[0009] Furthermore, the first slider is installed on a side of the mobile frame close to the jig frame assembly, and the first slider is slidably connected to the guide rail, and the guide pile and the first slider are fixedly connected to each other.

[0010] Furthermore, the upper end of the first hydraulic cylinder is fixedly connected to the bottom of the fixture table, and the lower end of the first hydraulic cylinder is fixedly connected to the lower end of the main frame.

[0011] Furthermore, the tube pressing assembly includes a pressing block, a connecting frame, a stabilizing frame and a second slider. The connecting frame is installed in the top center of the pressing block, and the stabilizing frames are symmetrically installed on the left and right sides of the top of the connecting frame, and the second slider is installed on the side of the stabilizing frame close to the jig frame assembly.

[0012] Furthermore, the side of the second sliding block away from the stabilizing frame is connected and fixed to the guide pile, and the second sliding block is in sliding connection with the guide rail.

[0013] Furthermore, the lower end of the second hydraulic cylinder is fixedly connected to the top of the connecting frame, and the upper end of the second hydraulic cylinder is fixedly connected to the upper end of the main frame.

[0014] The utility model provides a group frame pipe pressing fixture, which has the following beneficial effects:

[0015] 1. The utility model is characterized in that a movable frame is installed at the bottom of the support frame, and then a first slider on one side of the movable frame is slidably connected to the guide rail, and at the same time a group of guide piles are connected to the first slider, and a second slider on one side of the stabilizing frame is also slidably connected to the guide rail, and a group of guide piles are connected to the first slider. Therefore, under the operation of the servo motor, the bidirectional screw rod connected thereto will rotate vertically axially, thereby driving the guide piles at both ends to perform vertical lifting and translation, and then driving the jig assembly and the pressing pipe assembly connected thereto to be able to translate synchronously. By using the above structure, it is possible to ensure as much as possible that the jig assembly and the pressing pipe assembly can maintain sufficient structural stability during the movement, so as to ensure that the jig assembly and the pressing pipe assembly can avoid pressure leakage during the pressing of the steel pipe when pressing the group frame, so as to ensure the effectiveness and quality of processing, and at the same time ensure the flexibility of the device structure.

[0016] 2. The utility model installs a first limit block, a second limit block and a third limit block of different structures on the top edge of the jig table respectively, and utilizes a structural setting in which the edges of the three components can fit together with the edges of the group frame, and cooperates with the use of bolts to fix the first limit block, the second limit block and the third limit block respectively at the three edge positions of the top surface of the jig table, so that the structure of the group frame can be fixed and play a quick limiting structural role, which can effectively avoid the situation where the product is not put in place during the processing, thereby improving the processing quality. In addition, the main frame is used in conjunction with the structure of the first hydraulic cylinder and the second hydraulic cylinder. While providing stable structural support for the jig assembly and the pressing pipe assembly, it can also provide a smooth structural thrust to ensure that there is sufficient force in the pressing process to meet the processing needs.

Therefore, under the operation of the servo motor 503, the bidirectional screw rod 504 connected thereto will rotate vertically axially, thereby driving the guide piles 505 at both ends to perform vertical lifting and translation, and then driving the fixture assembly 1 and the pressure pipe assembly 3 connected thereto to be synchronously translated.

[0024] like Figures 1 to 4As shown, the jig assembly 1 includes a jig table 101, a first limit block 102, a second limit block 103 and a third limit block 104. The first limit block 102 is installed on the front edge of the top surface of the jig table 101, and the second limit block 103 is installed on the rear edge of the top surface of the jig table 101. In addition, the third limit block 104 is installed on one side edge of the top surface of the jig table 101. The jig assembly 1 includes a support frame 105, a movable frame 106 and a first slider 107.
