Description

Technical Field

[0001] This utility model belongs to the technical field of pressure testing tools, and specifically provides a synchronous pressure testing tool for compressor connecting rod bolts. Background Technology

[0002] The connecting rod of the compressor is connected to the crankshaft via connecting rod bolts. The preload of the connecting rod bolts directly affects the operating stability and service life of the compressor. Currently, the preload of connecting rod bolts is usually achieved using a hydraulic tensioner. This involves installing a pressure piston on the bolt, injecting high-pressure liquid to move the piston upward and stretch the bolt, tightening the nut while the bolt is stretched, and finally releasing the pressure to retract the bolt, thus creating a preload inside the bolt.

[0003] However, existing connecting rod bolt pressing tools have the following shortcomings in practical applications: Firstly, traditional pressure testing tools can usually only operate on a single bolt. For multiple bolts arranged in parallel on the compressor connecting rod, multiple pressure testing operations are required, which is not only inefficient, but also makes it difficult to ensure the consistency of the preload of each bolt, resulting in uneven force on the connecting rod and affecting the operating accuracy of the compressor. Secondly, because the spacing of the bolts on the compressor connecting rod varies depending on the model, the existing tools cannot flexibly adapt to bolts with different spacings, resulting in poor versatility. Third, when pressing multiple bolts, the operator needs to screw each pressure piston onto the corresponding bolt. The operation is cumbersome and it is difficult to ensure that the screwing progress of each pressure piston is synchronized, which further affects the uniformity of the pre-tightening effect.

[0004] Therefore, it is necessary to develop a tool that can simultaneously act on multiple bolts with adjustable spacing and can achieve synchronous bolting and synchronous pressure to improve the installation efficiency and pre-tightening quality of compressor connecting rod bolts. Utility Model Content

[0005] To solve the above problems, this utility model provides a synchronous pressing tool for compressor connecting rod bolts.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a synchronous pressing tool for compressor connecting rod bolts, comprising a pressing mounting body, a pressure body piston, and a piston adjusting assembly, wherein the two pressing mounting bodies are symmetrically distributed, and the lower ends of the two pressure body pistons are respectively assembled into the pressing mounting bodies; The piston adjustment assembly includes a housing, an adjusting component, a synchronous toothed belt, a bracket, and a drive gear. The two housings are symmetrically assembled on the two pressure mounting bodies. The adjusting component is movably assembled inside the housing, and the synchronous toothed belt is movably assembled on the inner wall of the adjusting component. A circular hole is opened on the upper surface of the housing, and the pressure body piston is rotatably assembled in the circular hole. A driven gear is integrally formed on the outer wall of the pressure body piston, and the driven gear meshes with the synchronous toothed belt. A bracket is assembled on the upper surface of the two housings, and a rotating shaft groove is opened on the upper surface of the bracket. The drive gear is located between the two driven gears and meshes with the synchronous toothed belt. A rotating shaft is fixedly installed on the upper end of the drive gear, and the rotating shaft is movably assembled in the rotating shaft groove. A handle is fixedly installed on the upper end of the rotating shaft.

[0007] Furthermore, the pressure mounting body includes a spacer ring and a pressure body. The pressure body is fixedly mounted on the spacer ring. A rectangular body is fixedly mounted on the outer wall of the pressure body. A connecting rod is inserted between the rectangular bodies of the two pressure mounting bodies. A slot is formed on the upper surface of the pressure body. A retaining strip is integrally formed on the lower surface of the housing and is inserted into the slot.

[0008] Furthermore, a pressure channel is formed on the upper surface of the pressure body piston, an annular cavity is formed at the lower end of the pressure body piston, and a connector is assembled at the upper end of the pressure channel.

[0009] Furthermore, the side wall of the housing is uniformly provided with lifting grooves, and the outer wall of the adjusting member is uniformly fixed with a lever plate corresponding to the lifting groove, and the lever plate is inserted into the lifting groove. The lower end of the inner wall of the housing is integrally formed with a base plate, and the lower end of the inner wall of the adjusting member is integrally formed with a support plate, and the support plate is placed on the base plate. The lower surface of the synchronous toothed belt is attached to the upper surface of the support plate.

[0010] Furthermore, the inner wall of the adjusting member is provided with a limiting groove, and the outer wall of the synchronous toothed belt is uniformly fixedly installed with limiting sliders, and the limiting sliders are moved and assembled in the limiting groove.

[0011] Furthermore, an upright plate is integrally formed on the inner side of the upper surface of the housing, and a transmission plate is fixedly installed on the inner wall of the upright plate. The transmission plate is in the shape of a right trapezoid, and the inclined surface of the transmission plate is in contact with the rotating shaft.

[0012] Furthermore, the bracket has a cross-shaped structure, and the rotating shaft groove is vertically opened in the middle of the bracket. The upper surface of the bracket is symmetrically provided with transverse grooves. An auxiliary connecting plate is movably assembled between the rear ends of the two upright plates of the housing. A rectangular frame is fitted on the outer wall of the auxiliary connecting plate. The rear end of the bracket is fixedly installed on the upper surface of the rectangular frame. A transverse slider is integrally formed on the front end of the upper surface of the upright plate, and the transverse slider is inserted into the transverse groove.

[0013] Furthermore, a column is fixedly installed on the upper front surface of the bracket, and a tension spring is fixedly installed between the column and the rotating shaft.

[0014] The beneficial effects of using this utility model are: This invention utilizes a synchronous toothed belt, a driving gear, and a driven gear integrally formed with the pressure body piston. When the handle is turned, the driving gear drives the two driven gears and the pressure body piston to rotate synchronously via the synchronous toothed belt. This enables the two pressure body pistons to be synchronously screwed onto the bolts under the same operation, significantly shortening the installation time. At the same time, it ensures that the screwing progress of the two bolts is completely consistent, creating conditions for subsequent synchronous pressure testing and effectively avoiding the problem of uneven preload caused by sequential screwing.

[0015] This utility model achieves stepless adjustment of the distance between the two pressure body pistons by sliding the shaft of the drive gear into the shaft groove of the bracket. When the shaft moves along the shaft groove, the drive gear drives the synchronous toothed belt to deform, which in turn drives the housing, the pressure mounting body and the pressure body piston to move inward or outward synchronously. This allows the same tool to be flexibly adapted to bolts with different spacings on the compressor connecting rod, significantly improving the tool's versatility and applicability.

[0016] This invention features a lifting groove on the side wall of the housing and a lever on the outer wall of the adjusting component. When the lever is pushed upward, the adjusting component and the synchronous toothed belt rise synchronously, causing the synchronous toothed belt to disengage from the driven gear on the pressure body piston. At this point, the two pressure body pistons no longer rotate synchronously. The operator can independently fine-tune a single pressure body piston as needed to compensate for inconsistent bolt thread lengths or installation position deviations, thereby further improving the tool's adaptability and operational flexibility.

[0026] 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.

[0027] Reference Figures 1 to 8 A synchronous pressing tool for compressor connecting rod bolts includes a pressing mounting body 1, a pressure body piston 2, and a piston adjusting assembly. The two pressing mounting bodies 1 are symmetrically distributed, and the lower ends of the two pressure body pistons 2 are respectively assembled in the pressing mounting body 1.

[0028] This pressure-pressurizing tool consists of two pressure-pressurizing mounting bodies 1. The distance between the two pressure-pressurizing mounting bodies 1 is adjustable, making it suitable for bolts with different spacing on the compressor connecting rod. The two pressure body pistons 2 are respectively rotatably mounted on the piston adjustment assembly. The piston adjustment assembly enables the synchronous rotation of the two pressure body pistons 2, and the pressure body pistons 2 can be finely adjusted after operation.

[0029] Adjust the positions of the two pressure-pressing mounting bodies 1 according to the bolt spacing, and then put the two pressure-pressing mounting bodies 1 onto the bolts respectively, with the nuts located inside the spacer ring 11. Then, place the two pressure body pistons 2 into the two pressure-pressing mounting bodies 1 respectively, and use the piston adjustment assembly to synchronously rotate the two pressure body pistons 2 and screw them onto the bolts, thus completing the installation of the two pressure body pistons 2 in this pressure-pressing tool in one operation.

[0030] The piston adjustment assembly includes a housing 4, an adjusting component 5, a synchronous toothed belt 6, a bracket 7, and a drive gear 8. Two housings 4 are symmetrically assembled on two pressure mounting bodies 1. The adjusting component 5 is movably assembled inside the housing 4. The synchronous toothed belt 6 is movably assembled on the inner wall of the adjusting component 5. A circular hole is opened on the upper surface of the housing 4, and the pressure body piston 2 is rotatably assembled in the circular hole. A driven gear 21 is integrally formed on the outer wall of the pressure body piston 2, and the driven gear 21 meshes with the synchronous toothed belt 6. A bracket 7 is assembled on the upper surface of the two housings 4. A rotating shaft groove 72 is opened on the upper surface of the bracket 7. The drive gear 8 is located between the two driven gears 21 and meshes with the synchronous toothed belt 6. A rotating shaft 81 is fixedly installed on the upper end of the drive gear 8, and the rotating shaft 81 is movably assembled in the rotating shaft groove 72. A handle 82 is fixedly installed on the upper end of the rotating shaft 81.

[0031] pass Figure 5 It can be seen that the shape of shell 4 is composed of three parts. Figure 5 The upper part is a horizontal straight line segment, the middle part is an arc segment, and the lower part is an inclined straight line segment sloping downwards; the shaft groove 72 is located between the inclined straight lines of the two housings 4. When the drive gear 8 moves forward along the shaft groove 72, it will drive the synchronous toothed belt 6 to bulge forward. The inclined straight line segment provides space for the deformation of the synchronous toothed belt 6.

[0032] The contour shape of the adjusting member 5 is the same as that of the housing 4. The function of the adjusting member 5 is to support and limit the synchronous toothed belt 6.

[0033] The bracket 7 is mainly used to limit and guide the position of the rotating shaft 81, so that the rotating shaft 81 and the drive gear 8 are located on the symmetrical plane of the two housings 4, and can only move forward and backward.

[0034] By rotating the handle 82, the drive gear 8 can be driven to rotate, which in turn drives the synchronous toothed belt 6 to move, and finally drives the driven gear 21 and the pressure body piston 2 to rotate, completing the screw connection of the pressure body piston 2 on the bolt, and completing the installation of the pressure body piston 2 on the pressure mounting body 1.

[0035] like Figure 5As shown, the two pressure body pistons 2 are at their furthest point. The rotating shaft 81 is located at the rearmost position of the rotating shaft groove 72. The overall shape of the synchronous toothed belt 6 is a ring-shaped racetrack. At this time, the driving gear meshes with the synchronous toothed belt 6. When the rotating shaft 81 moves forward, the driving gear 8 moves forward and drives the shape of the synchronous toothed belt 6 to change. The front section of the synchronous toothed belt 6 protrudes forward, and at the same time, it moves its two sides inward, which in turn drives the housing 4 and the pressure body pistons 2 to move inward, thus completing the adjustment of the distance between the two pressure body pistons 2. This is suitable for bolts with different spacing on the compressor connecting rod. When the shape of the synchronous toothed belt 6 changes, the pressure body pistons 2 and the driven gear 21 will deflect with the change of the synchronous toothed belt 6, and always remain meshed.

[0036] Specifically, such as Figure 1 and Figure 3 As shown, the pressure mounting body 1 includes a spacer ring 11 and a pressure body 12. The pressure body 12 is fixedly mounted on the spacer ring 11. A rectangular body 13 is fixedly mounted on the outer wall of the pressure body 12. A connecting rod 14 is inserted between the rectangular bodies 13 of the two pressure mounting bodies 1. A slot 121 is opened on the upper surface of the pressure body 12. A retaining strip 45 is integrally formed on the lower surface of the housing 4, and the retaining strip 45 is inserted into the slot 121.

[0037] Spacer 11 is fitted onto nut, and grooves are provided on the side wall of spacer 11 to facilitate the rotation and tightening of nut after pressurization; pressure body 12 is used to assemble pressure body piston 2.

[0038] Specifically, such as Figure 6 As shown, a pressure channel 22 is provided on the upper surface of the pressure body piston 2, an annular cavity 23 is provided at the lower end of the pressure body piston 2, and a connector 3 is assembled at the upper end of the pressure channel 22.

[0039] The two connectors 3 can be connected in series to the same hydraulic pump to ensure that the two pressure body pistons 2 perform the stretching, pressure holding and pressure release processes simultaneously, which greatly improves work efficiency.

[0040] Sealing structures are installed on the pressure body piston 2 and inside the pressure body 12 respectively; the annular cavity 23 forms a pressure chamber with the inner end face of the pressure body 12 and the stepped surface of the pressure body piston 2; after the pressure body piston 2 is screwed onto the bolt and tightly placed inside the pressure body 12, pressurized fluid is injected through the connector 3. The pressurized fluid flows through the pressure channel 22 to the annular cavity 23 and the pressure chamber, slowly pressurizing and driving the pressure body piston 2 to move upward, thereby stretching the bolt. After reaching the predetermined pressure, the pressurization stops, and then the nut is turned to tighten. Finally, the pressure is released and the pressurization tool is disassembled; this pressurization tool can simultaneously pressurize two bolts, which is simple to operate and improves work efficiency.

[0041] Specifically, such as Figure 1 , Figure 7 and Figure 8 As shown, the side wall of the housing 4 is evenly provided with lifting grooves 41, and the outer wall of the adjusting member 5 is evenly fixed with a lever 53 corresponding to the lifting groove 41, and the lever 53 is inserted into the lifting groove 41. The lower end of the inner wall of the housing 4 is integrally formed with a base plate, and the lower end of the inner wall of the adjusting member 5 is integrally formed with a support plate 52, and the support plate 52 is placed on the base plate. The lower surface of the synchronous toothed belt 6 is attached to the upper surface of the support plate 52.

[0042] For the base plate and the support plate 52, the width of the part located in the horizontal straight section of the housing 4 is narrower, and the width of the part located in the inclined straight section is wider. The purpose is that when the synchronous toothed belt 6 is in the shape of a circular runway, the support plate 52 can still support the synchronous toothed belt 6.

[0043] For the pressure body piston 2, after it is fully installed on the pressure body 12, a part of it is located on the outside of the pressure body. For this part, the lower section is equipped with a driven gear 21, the middle section is a smooth cylindrical surface, and the outer diameter of the cylindrical surface is the same as the root circle diameter of the driven gear 21. An annular groove is opened on the cylindrical surface. The pressure body piston 2 is installed in the circular hole on the housing 4 through the annular groove. An annular structure is installed on the upper outer wall of the pressure body piston 2, and the outer diameter of the annular structure is equal to the outer diameter of the cylindrical surface. The figure shows it as an integral piece, but in reality, it can be installed by spline connection.

[0044] By pushing the dial 53 upward, the height of the adjusting piece 5 in the housing 4 can be adjusted, thereby adjusting the height of the synchronous toothed belt 6. When the synchronous toothed belt 6 moves to the smooth cylindrical surface of the pressure body piston 2, the two pressure body pistons 2 no longer rotate synchronously. At this time, the pressure body piston 2 can be finely adjusted in the pressure body 12 by rotating the ring structure, increasing the adaptability of this pressure tool.

[0045] Regarding the driven gear 21 and the synchronous toothed belt 6, in order to facilitate the synchronous toothed belt 6 to move down and mesh with the driven gear 21, chamfers can be provided on the upper side of the tooth profile of the driven gear 21 and the lower side of the tooth profile of the synchronous toothed belt 6 to facilitate docking; at the same time, during the docking process, the driving gear 8 can be rotated to ensure that the tooth profiles of the driven gear 21 and the synchronous toothed belt 6 can be effectively docked.

[0046] The tooth width of the driving gear 8 is twice that of the driven gear 21, so it will still mesh with the driving gear 8 after the synchronous toothed belt 6 moves upward.

[0047] The lifting slide 41 can be set to an isosceles trapezoidal shape. When the pallet 52 moves upward, the lifting slide 41 will gradually increase the clamping force on the pallet 52 to ensure that the pallet 52 will not be reset under the action of gravity after it moves upward, and to prevent the pallet 52 at the bottom from moving upward due to vibration, thus ensuring the stability of the transmission.

[0048] Specifically, such as Figure 3 and Figure 8 As shown, the inner wall of the adjusting member 5 is provided with a limiting groove 51, and the outer wall of the synchronous toothed belt 6 is uniformly fixedly installed with a limiting slider 61, and the limiting slider 61 is movably assembled in the limiting groove 51.

[0049] The cooperation between the limiting slide groove 51 and the limiting slider 61 ensures the stability of the synchronous toothed belt 6 movement and also plays an auxiliary limiting role.

[0050] Specifically, such as Figure 2 and Figure 5 As shown, an upright plate 42 is integrally formed on the inner side of the upper surface of the housing 4, and a transmission plate 43 is fixedly installed on the inner wall of the upright plate 42. The transmission plate 43 is in the shape of a right trapezoid, and the inclined surface of the transmission plate 43 is in contact with the rotating shaft 81.

[0051] The transmission plates 43 of the two housings 4 are combined to form a V-shaped groove structure. The inclined surface of the transmission plate 43 is designed by calculation, and the specific shape is adjusted according to the actual application. It can be an inclined surface or a curved surface. The purpose is to ensure that when the rotating shaft 81 moves, the inclined surface of the transmission plate 43 always fits against the outer wall of the rotating shaft 81.

[0052] When the pressure tool is in its initial state, the rotating shaft 81 is located at the foremost position of the rotating shaft groove 72. At this time, the two housings 4 and the pressure body piston 2 are in the closest position, the transmission plate 43 has the largest overlapping area and the inclined surface is attached to the outer wall of the rotating shaft 81, and the two rectangular bodies 13 are attached. When it is necessary to adjust the distance between the two pressure body pistons 2, the rotating shaft 81 is pushed backward. The rotating shaft 81 will push the two transmission plates 43 to move to both sides, and then push the housings 4 and the pressure body pistons 2 to move to both sides, thus completing the operation of increasing the distance. At the same time, the synchronous toothed belt 6 also deforms.

[0053] The position of the rotating shaft 81 can also be defined by the two transmission plates 43.

[0054] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the bracket 7 has a cross-shaped structure, and the rotating shaft groove 72 is vertically opened in the middle of the bracket 7. The upper surface of the bracket 7 is symmetrically provided with transverse grooves 73. An auxiliary connecting plate 46 is movably assembled between the rear ends of the upright plates 42 of the two housings 4. A rectangular frame 71 is fitted on the outer wall of the auxiliary connecting plate 46. The rear end of the bracket 7 is fixedly installed on the upper surface of the rectangular frame 71. A transverse slider 44 is integrally formed on the front end of the upper surface of the upright plate 42, and the transverse slider 44 is inserted into the transverse groove 73.

[0055] The bracket 7 is installed on the housing 4 through the cooperation of the rectangular frame 71, two transverse sliding grooves 73 and transverse slider 44. Since the transmission plate 43 limits the position of the rotating shaft 81, the position of the bracket 7 is relatively fixed. When the rotating shaft 81 moves, the two housings 4 move laterally relative to the transverse sliding grooves 73.

[0056] Specifically, such as Figure 1 As shown, a column 74 is fixedly installed on the upper front surface of the bracket 7, and a tension spring 9 is fixedly installed between the column 74 and the rotating shaft 81.

[0057] The tension spring 9 is always in a stretched state. That is, when the rotating shaft 81 is at the front end of the rotating shaft groove 72, the tension spring 9 still applies tension to the rotating shaft. Therefore, when the piston adjustment assembly is removed after the pressing work is completed, the tension of the tension spring 9 will cause the rotating shaft 81 to move to the front end and cause the housing 4 and the pressure body piston 2 to move inward for reset. In use, after pushing the rotating shaft 81 backward to adjust the spacing, the pressure body piston 2 is placed in the pressure body 12 and screwed onto the bolt. At this time, the pressure body piston 2 is accurately positioned by pressing the mounting body 1 and the bolt.

[0058] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of this utility model. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this utility model.
