Description

Technical Field

[0001] This utility model relates to the field of internal combustion engine assembly technology, and specifically to an internal combustion engine body that is easy to assemble. Background Technology

[0002] An internal combustion engine is a type of power machinery that converts the heat energy released from the combustion of fuel inside the machine into power. The main function of the internal combustion engine block is to support the moving parts of the crankshaft and connecting rod mechanism and maintain their correct relative positions. Inside the cylinder block, there are many reinforcing ribs, cooling water jackets, and lubrication oil passages, which withstand the various forces generated during the operation of the internal combustion engine. The internal combustion engine block is usually divided into an upper part and a lower part. The upper part is where the cylinders are installed, and the lower part is the crankcase where the crankshaft is installed. The upper and lower parts of the internal combustion engine block are cast together as a whole.

[0003] A search revealed existing technology (publication number: CN217728554U), which describes "a high-strength, easily assembled internal combustion engine body, including a base plate, a rotary drive unit on the upper surface of the base plate, a placement part on the upper surface of the rotary drive unit, and an engine body on the upper surface of the placement part. The rotary drive unit includes a drive box mounted on the upper surface of the base plate, a rotating column rotatably connected to the inner bottom wall of the drive box, a turbine fixedly connected to the surface of the rotating column, and two support blocks fixedly connected to the inner bottom wall of the drive box. The two support blocks are rotatably connected to the same worm gear on their opposite faces. This invention uses the output end of a rotary motor to drive the worm gear to rotate, which in turn drives the turbine gear to rotate, which in turn drives the rotating column to rotate. The rotating column drives the placement part to rotate, thereby causing the engine body to turn, making it convenient for users to assemble various parts onto the engine body. Thus, this high-strength, easily assembled internal combustion engine body solves the problem of inconvenient assembly of internal combustion engine bodies in the prior art."

[0004] While existing assembly-friendly internal combustion engine blocks achieve the effect of facilitating internal combustion engine assembly, they still have some shortcomings: In the aforementioned patent documents, when using the assembly-friendly internal combustion engine block, the internal combustion engine is directly placed on the mounting plate. Because it is impossible to keep the internal combustion engine precisely centered on the mounting plate, the clamping plates on both sides cannot simultaneously contact the internal combustion engine. Therefore, one clamping plate inevitably pushes the internal combustion engine to slide on the mounting plate, generating friction between the internal combustion engine and the mounting plate. Since the internal combustion engine itself is heavy, this friction may adversely affect the contact surface between the internal combustion engine and the mounting plate. Secondly, the clamping force of the clamping plates cannot be determined, i.e., it is impossible to determine whether they provide a stable clamping effect on the internal combustion engine. Excessive clamping force will lead to an excessive load on the mounting motor. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, an internal combustion engine block that is easy to assemble is provided to solve the problems mentioned in the background.

[0006] To achieve the above objectives, an internal combustion engine block that is easy to assemble is provided, comprising: a base plate, a rotary drive unit connected to the upper end of the base plate, and a fixed plate rotatably connected to the upper end of the rotary drive unit; a guide rail provided at the upper end of the fixed plate, and a placement plate slidably connected to the upper end of the guide rail; an internal combustion engine body provided on the upper side of the placement plate; a clamping assembly provided on the upper side of the fixed plate and between the guide rails; the clamping assembly includes end plates fixed to both ends of the fixed plate; a motor is mounted on the outer wall of one end plate; a lead screw is rotatably connected between the end plates; a screw plate is screwed to the outer side of the lead screw; a guide rod is slidably connected inside the screw plate; an intermediate plate is connected to the inner end of the guide rod; a pressure sensor is connected to the inner end of the intermediate plate; and a clamping plate is connected to the inner end of the pressure sensor.

[0007] Furthermore, the clamping assembly also includes a guide groove on the upper end of the fixing plate, and the guide groove is parallel to the middle of the two guide rails, and the lower end of the screw plate is slidably connected inside the guide groove.

[0008] Furthermore, the outer end of the guide rod is connected to a limit block, and the guide rod has two parallel rods.

[0009] Furthermore, the pressure sensor is bolted between the intermediate plate and the clamping plate, and the pressure sensor is electrically connected to the motor via an external controller.

[0010] Furthermore, the inner end of the clamping plate is provided with a buffer pad, and the clamping plate and the screw plate are provided with two sets symmetrical about the center of the lead screw, and the clamping plate is higher than the upper end of the placement plate.

[0011] Furthermore, the upper end of the placement plate is provided with an anti-slip pad, and the lower end of the placement plate is provided with a track groove, and the guide rail is slidably connected inside the track groove.

[0012] Furthermore, the length of the fixing plate is greater than that of the guide rail, and the length of the guide rail is greater than that of the placement plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In use, first place the internal combustion engine body on the placement plate, then start the motor included in the clamping assembly, so that the motor drives the screw plate to move closer through the drive screw. At this time, no matter which side of the clamping plate contacts the internal combustion engine body first, a thrust will be applied to the internal combustion engine body. Then, through the sliding connection between the placement plate and the guide rail, the internal combustion engine body is pushed towards the other clamping plate until both clamping plates are in clamping contact with the internal combustion engine. Since the internal combustion engine body forms an overall movement effect with the placement plate through the anti-slip pad, and through the small area of ​​sliding contact between the guide rail and the placement plate, the sliding friction is reduced, which better protects the contact surface of the internal combustion engine body base and the placement plate.

[0015] 2. When the two sets of clamping plates maintain pressure contact with the internal combustion engine, the clamping force is detected by the pressure sensors on both sides. When the clamping force on both sides reaches the set threshold, the motor is stopped by the external controller, which makes it easier to determine the clamping force and ensures a stable clamping effect on the internal combustion engine body.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1 to 4As shown, this utility model provides an internal combustion engine body that is easy to assemble, including: a base plate 1, a rotary drive unit 2 connected to the upper end of the base plate 1, and a fixed plate 3 rotatably connected to the upper end of the rotary drive unit 2, a guide rail 4 provided at the upper end of the fixed plate 3, a placement plate 5 slidably connected to the upper end of the guide rail 4, and an internal combustion engine body 6 provided on the upper side of the placement plate 5, a clamping assembly 7 provided on the upper side of the fixed plate 3 and between the guide rails 4, and the clamping assembly 7 includes end plates fixed to both ends of the fixed plate 3, and a motor 71 is installed on the outer wall of one of the end plates, while a lead screw 72 is rotatably connected between the end plates, a screw plate 77 is screwed to the outer side of the lead screw 72, and a guide rod 78 is slidably connected inside the screw plate 77, and an intermediate plate 76 is connected to the inner end of the guide rod 78, a pressure sensor 75 is connected to the inner end of the intermediate plate 76, and a clamping plate 74 is connected to the inner end of the pressure sensor 75.

[0023] In this embodiment, the base plate 1, the rotary drive unit 2, the fixing plate 3, the guide rail 4, the placement plate 5, and the clamping assembly 7 constitute the main body structure of the internal combustion engine body that is easy to assemble as described in this application.

[0024] It should be noted that the internal combustion engine body structure involved in this application is actually a body structure for internal combustion engine assembly, rather than the internal combustion engine body itself. It is mainly used to adjust the angle and position of the internal combustion engine during the assembly process in order to improve assembly efficiency.

[0025] The base plate 1 and the rotary drive unit 2 involved adopt the same structure as those described in the prior art document, and their structure and principle have been fully disclosed in the prior art document. That is, the base plate 1 realizes the linear movement of the internal combustion engine, and the rotary drive unit 2 realizes the rotary movement of the internal combustion engine.

[0026] like Figures 1 to 4 In the clamping assembly 7, a guide groove 73 is opened at the upper end of the fixed plate 3, and the guide groove 73 is parallel to the middle of the two guide rails 4. The lower end of the screw plate 77 is slidably connected inside the guide groove 73. The outer end of the guide rod 78 is connected to the limit block 79, and the guide rod 78 has two parallel rods. The pressure sensor 75 is bolted between the intermediate plate 76 and the clamping plate 74, and the pressure sensor 75 is electrically connected to the motor 71 through an external controller. The inner end of the clamping plate 74 is provided with a buffer pad, and the clamping plate 74 and the screw plate 77 are provided with two sets of symmetrical about the center of the lead screw 72. The clamping plate 74 is higher than the upper end of the placement plate 5. The upper end of the placement plate 5 is provided with an anti-slip pad 51, and the lower end of the placement plate 5 is provided with a track groove 52. The guide rail 4 is slidably connected inside the track groove 52. The length of the fixed plate 3 is greater than that of the guide rail 4, and the length of the guide rail 4 is greater than that of the placement plate 5.

[0027] As a preferred implementation, by setting a limiting block 79, when the clamping plate 74 releases the internal combustion engine body 6, it can contact the limiting block 79 when the bolt plate 77 moves outward, and then the clamping plate 74 is moved outward by the limiting block 79 and the guide rod 78.

[0028] Specifically, after the pressure sensor 75 is set with a threshold by an external controller, it is electrically connected to the start-stop circuit of the motor 71. When the pressure sensors 75 on both sides of the internal combustion engine body 6 reach the set threshold, they simultaneously send a signal to control the motor 71 to stop.

[0029] It should be noted that the threshold setting of the pressure sensor 75 is greater than the thrust when the clamp 74 on one side comes into contact with the internal combustion engine body 6. That is, when the internal combustion engine body 6 is pushed and glided, the thrust generated will not control the motor 71 to stop.

[0030] Specifically, the inner wall of the track groove 52 is provided with ball bearings, which enable rolling connection with the guide rail 4, thereby making the static friction between the internal combustion engine body 6 and the anti-slip pad 51 greater than the rolling friction between the placement plate 5 and the guide rail 4.

[0031] In use, the internal combustion engine body is first placed on the placement plate. Then, the motor included in the clamping assembly is started, causing the motor to drive the screw plate to move closer via the drive screw. At this point, regardless of which side of the clamping plate contacts the internal combustion engine body first, a thrust will be applied to the internal combustion engine body. Then, through the sliding connection between the placement plate and the guide rail, the internal combustion engine body is pushed towards the other clamping plate until both clamping plates are in contact with the internal combustion engine. Because the internal combustion engine body forms an overall movement effect with the placement plate through the anti-slip pad, and through the small-area sliding contact between the guide rail and the placement plate, the sliding friction is reduced, better protecting the contact surface of the internal combustion engine body base and the placement plate. When the two sets of clamping plates maintain pressure contact with the internal combustion engine, the clamping force is detected by the pressure sensors on both sides. When the clamping force on both sides reaches the set threshold, the motor is stopped by the external controller, which facilitates the determination of the clamping force and ensures a stable clamping effect on the internal combustion engine body.

[0032] The easily assembled internal combustion engine body of this utility model can effectively solve the problems mentioned in the background art. Based on the existing easily assembled internal combustion engine body technology, it has a protective effect during the clamping process of the internal combustion engine, and has the effect of detecting the clamping force and achieving stable clamping.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
